d50084a299 [PATCH] uml: Formatting changes
This patch makes a bunch of non-functional changes -
    return(foo); becomes return foo;
    some statements are broken across lines for readability
    some trailing whitespace is cleaned up
    open_one_chan took four arguments, three of which could be
       deduced from the first.  Accordingly, they were eliminated.
    some examples of "} else {" had a newline added
    some whitespace cleanup in the indentation
    lines_init got some control flow cleanup
    some long lines were broken
    removed another emacs-specific C formatting comment

1b57e9c278 [PATCH] uml: non-void functions should return something
There are a few functions which are declared to return something, but don't.
These are actually infinite loops which are forced to be declared as non-void.
 This makes them all return 0.

970d6e3a34 [PATCH] uml: use kstrdup
There were a bunch of calls to uml_strdup dating from before kstrdup was
introduced.  This changes those calls.  It doesn't eliminate the definition
since there is still a couple of calls in userspace code (which should
probably call the libc strdup).

76865c3f87 [PATCH] i386: ioapic virtual wire mode fix
o Currently, during kexec reboot, IOAPIC is re-programmed back to virtual
  wire mode if there was an i8259 connected to it. This enables getting
  timer interrupts in second kernel in legacy mode.

o After putting into virtual wire mode, IOAPIC delivers the i8259 interrupts
  to CPU0. This works well for kexec but not for kdump as we might crash
  on a different CPU and second kernel will not see timer interrupts.

o This patch modifies the redirection table entry to deliver the timer
  interrupts to the cpu we are rebooting (instead of hardcoding to zero).
  This ensures that second kernel receives timer interrupts even on a
  non-boot cpu.

f8af095d3a [PATCH] x86: change_page_attr() fix
The 'make rodata read-only' patch in -mm exposes a latent bug in the 32-bit
change_page_attr() function, which causes certain CPUs (Those with NX
basically) to reboot instantly after pages are marked read-only.

The same bug got fixed a while back on x86-64, but never got propagated to
i386.

Stuart Hayes from Dell also picked up on this last June, but it never got
fixed, as the only thing affected by it aparently was the nvidia driver.

Blatantly stealing description from his post..

"It doesn't appear to be fixed (in the i386 arch).  The
 change_page_attr()/split_large_page() code will still still set all the
 4K PTEs to PAGE_KERNEL (setting the _PAGE_NX bit) when a large page
 needs to be split.

 This wouldn't be a problem for the bulk of the kernel memory, but there
 are pages in the lower 4MB of memory that's free, and are part of large
 executable pages that also contain kernel code.  If change_page_attr()
 is called on these, it will set the _PAGE_NX bit on the whole 2MB region
 that was covered by the large page, causing a large chunk of kernel code
 to be non-executable."

Allow SPARSEMEM to be enabled on non-numa x86 systems.  This is made

The plan is to have no options and no selector as normal when
!EXPERIMENTAL.  When EXPERIMENTAL we enable the FLATMEM and SPARSEMEM
options for X86_PC whilst maintaining DISCONTIGMEM and SPARSEMEM for NUMA.

c728252c7a [PATCH] x86/x86_64: mark rodata section read only: generic x86-64 bugfix
Bug fix required for the .rodata work on x86-64:

when change_page_attr() and friends need to break up a 2Mb page into 4Kb
pages, it always set the NX bit on the PMD, which causes the cpu to consider
the entire 2Mb region to be NX regardless of the actual PTE perms.  This is
fine in general, with one big exception: the 2Mb page that covers the last
part of the kernel .text!  The fix is to not invent a new permission for the
new PMD entry, but to just inherit the existing one minus the PSE bit.

5fe9fe3c6f [PATCH] x86: Pnp byte granularity
The one remaining caller of set_limit, the PnP BIOS code, calls into the PnP
BIOS, passing kernel parameters in and out.  These parameteres may be passed
from arbitrary kernel virtual memory, so they deserve strict protection to
stop a bad BIOS from smashing beyond the object size.

Unfortunately, the use of set_limit was badly botching this by setting the
limit in terms of pages, when it really should have byte granularity.

When doing this, I discovered my BIOS had the buggy code during the "get
system device node" call:

 mov ax, es:[bx]

Which is harmless, but has a trivial workaround.

3012d2d209 [PATCH] x86: Always relax segments
APM BIOSes have many bugs regarding proper representation of the appropriate
segment limits for calling the BIOS.  By default, APM_RELAX_SEGMENTS is always
turned on to support running the APM BIOS on these buggy machines.  Keeping
64k limits poses very little danger to the kernel, because the pages where the
APM BIOS is located will always be in low physical memory BIOS areas, which
should already be marked reserved, and only buggy BIOSes would possibly
overstep the segment bounds with writes to data anyway.

Since forcing stricter limits breaks many machines and is not default
behavior, it seems reasonable to deprecate the older code which may cause APM
BIOS to fault.

If you really have a badly enough broken APM BIOS that you have to turn off
APM_RELAX_SEGMENTS, seems like the best recourse here would be to disable the
APM BIOS and / or not compile it into your kernel to begin with, and / or add
your system to the known bad list.

The reason I want to deprecate this code is there is underlying brokenness
with the set_limit macros, and getting rid of many of the call sites rather
than rewriting them seems to be the simplest and most correct course of
action.

e43d674f44 [PATCH] i386: don't blindly enable interrupts in die()
Rather than blindly re-enabling interrupts in die(), save their state
upon entry and then restore that state.

If the kernel is in really bad condition and faults with interrupts disabled,
re-enabling them in die() may cause even more trouble, implying more chances
of data corruption.

7c4cb60e5b [PATCH] x86: GDT alignment fix
Make GDT page aligned and page padded to support running inside of a
hypervisor.  This prevents false sharing of the GDT page with other hot
data, which is not allowed in Xen, and causes performance problems in
VMware.

Rather than go back to the old method of statically allocating the GDT
(which wastes unneded space for non-present CPUs), the GDT for APs is
allocated dynamically.

fef2b580eb [PATCH] frv: improve signal handling
The attached patch improves the signal handling:

 (1) It makes do_signal() static as it isn't called from anywhere outside of
     the arch code.

 (2) It removes the regs argument to all the static functions within that file,
     using __frame instead (which is the same thing held in a global register).

8efc0ab50e [PATCH] frv: fix signal handling
The attached patch makes FRV signal handling work properly:

 (1) After do_notify_resume() has been called, the work flags must be checked
     again (there may be another signal to deliver or the process might require
     rescheduling for instance).

 (2) After the signal frame is set up on the userspace stack, ptrace() should
     be given an opportunity to single-step into the signal handler.

 (3) The error state from setting up a signal frame should be passed back up
     the call chain.

 (4) The segfault handler shouldn't be preemptively reset in the arch if we
     fail to deliver a SEGV signal: force_sig() will take care of that.

54e269ead6 [ARM] 3226/1: IXP4xx runtime expansion bus window size configuration
Patch from Deepak Saxena

The expansion bus on the IXP46x NPU can be configured for either 32MiB or
16MiB windows and changing the configuration causes the base address for
each chip select for each region to change. Because of this, we cannot
hardcode the physical base as we currently do. This patch checks the
expansion bus configuration registers at runtime to determine the
appropriate window size. Note that this requires that the bootloader
already configured the device sizes appropriately, but I feel that is
valid assumption to make as the bootloader must configure and access
the flash window, the output display (LCD, LEDs, etc) window, and
other expansion bus devices.

3145d8a6cc [ARM] 3215/1: Iomega NAS 100d (MACH_NAS100D) machine support
Patch from Rod Whitby

This patch adds support for a new arm/ixp4xx machine - the Iomega NAS 100d network attached storage product.  The NAS100D is a consumer device containing a 266MHz Intel IXP420 processor, 16MB of flash, 64MB of RAM, a 160Gb internal IDE hard disk, and 802.11b/g wireless on an Atheros mini-PCI card.

Work on porting the latest 2.6.x kernel to this device is being done by
the NSLU2-Linux project (the same team who maintains the port to the
Linksys NSLU2 device).  In particular, the majority of this patch was
authored by Alessandro Zummo, based on the work done for MACH_NSLU2
support by the NSLU2-Linux core team of developers.

MACH_NAS100D (as implemented by this patch) can be enabled in jumbo
ixp4xx kernels without any affect on the other machines supported by
that kernel.

This patch applies cleanly against 2.6.15-rc7 and should be trivial to
apply to later kernel versions. It does not depend upon any other
patches.

f7e8bbb820 [ARM] 3192/1: Remove gpio_isr_line_clear() API from IXP4xx
Patch from Deepak Saxena

Other than interrupt masking purposes, this API is only used when
configuring interrupt lines and this patch moves that functionality
directly into the ixp4xx_set_irq_type() implementation as board level
PCI code should not need to worry about those details.

516949480d [PATCH] uml: fix random segfaults at bootup
Don't use printk() where "current_thread_info()" is crap.

Until when we switch to running on init_stack, current_thread_info() evaluates
to crap. Printk uses "current" at times (in detail, &current is evaluated with
CONFIG_DEBUG_SPINLOCK to check the spinlock owner task).

And this leads to random segmentation faults.

Exactly, what happens is that &current = *(current_thread_info()), i.e. round
down $esp and dereference the value. I.e. access the stack below $esp, which
causes SIGSEGV on a VM_GROWSDOWN vma (see arch/i386/mm/fault.c).

8b1af56b29 powerpc: Fix i8259 cascade on pSeries with XICS interrupt controller
It turns out that commit f9bd170a87
broke the cascade from XICS to i8259 on pSeries machines; specifically
we ended up not ever doing the EOI on the XICS for the cascade.  The
result was that interrupts from the serial ports (and presumably any
other devices using ISA interrupts) didn't get through.  This fixes
it and also simplifies the code, by doing the EOI on the XICS in the
xics_get_irq routine after reading and acking the interrupt on the
i8259.

7c612bfd4e [ARM] 3210/1: add missing memory barrier helper for NPTL support
Patch from Nicolas Pitre

Strictly speaking, the NPTL kernel helpers are required for pre ARMv6
only.  They are available on ARMv6+ as well for obvious compatibility
reasons.  However there are cases where extra memory barriers are needed
when using an SMP ARMv6 machine but not on pre-ARMv6.

This patch adds a memory barrier kernel helper that glibc can use as
needed for pre-ARMv6 binaries to be forward compatible with an SMP
kernel on ARMv6, as well as the necessary dmb instructions to the
cmpxchg helper.

I think (and testing on some GCC versions shows) this patch avoids the
fundamental issue which is behind this, namely gcc using the stack when
we have just replaced it, behind gcc's back.  The remapping and storage
of the return value is hidden in a blob of asm, hopefully giving gcc no

d74700e604 [IA64-SGI] Missed TLB flush
I see why the problem exists only on SN. SN uses a different hardware
mechanism to purge TLB entries across nodes.

It looks like there is a bug in the SN TLB flushing code. During context switch,
kernel threads inherit the mm of the task that was previously running on the
cpu. This confuses the code in sn2_global_tlb_purge().

The result is a missed TLB purge for the task that owns the "borrowed" mm.

(I hit the problem running heavy stress where kswapd was purging code pages of
a user task that woke kswapd. The user task took a SIGILL fault trying to
execute code in the page that had been ripped out from underneath it).

c2e2611425 [ARM] 3205/1: Handle new EABI relocations when loading kernel modules.
Patch from Daniel Jacobowitz

Handle new EABI relocations when loading kernel modules.  This is
necessary for CONFIG_AEABI kernels, and also for some broken
(since fixed) old ABI toolchains.

8309cf66fd [PATCH] x86_64: Bug correction in populate_memnodemap()
As reported by Keith Mannthey, there are problems in populate_memnodemap()

The bug was that the compute_hash_shift() was returning 31, with incorrect
initialization of memnodemap[]

To correct the bug, we must use (1UL << shift) instead of (1 << shift) to
avoid an integer overflow, and we must check that shift < 64 to avoid an
infinite loop.

fd4954714e [PATCH] x86_64: Fix collision between pmtimer and pit/hpet
On systems that do not support the HPET legacy functions (basically the IBM
x460, but there could be others), in time_init() we accidentally fall into a
PM timer conditional and set the vxtime_hz value to the PM timer's frequency.
We then use this value with the HPET for timekeeping.

This patch (which mimics the behavior in time_init_gtod) corrects the
collision.

d6ece5491a [PATCH] i386/x86-64 Correct for broken MCFG tables on K8 systems
They report all busses as MMCONFIG capable, but it never works for the
internal devices in the CPU's builtin northbridge.

It just probes all func 0 devices on bus 0 (the internal northbridge is
currently always on bus 0) and if they are not accessible using MCFG they are
put into a special fallback bitmap.

On systems where it isn't we assume the BIOS vendor supplied correct MCFG.

Requires the earlier patch for mmconfig type1 fallback

When there is no entry for a bus in MCFG fall back to type1.  This is
especially important on K8 systems where always some devices can't be accessed
using mmconfig (in particular the builtin northbridge doesn't support it for
its own devices)

bf5421c309 [PATCH] i386/x86-64: Don't call change_page_attr with a spinlock held
It's illegal because it can sleep.

Use a two step lookup scheme instead.  First look up the vm_struct, then
change the direct mapping, then finally unmap it.  That's ok because nobody
can change the particular virtual address range as long as the vm_struct is
still in the global list.

Also added some LinuxDoc documentation to iounmap.

Disabling LAPIC timer isn't sufficient.  In some situations, such as we
enabled NMI watchdog, there is still unexpected interrupt (such as NMI)
invoked in offline CPU.  This also avoids offline CPU receives spurious
interrupt and anything similar.
