This moves the macro loaddebug from asm-i386/suspend.h to
asm-i386/processor.h, which is the place that makes sense for it to be
defined, removes the extra copy of the same macro in
arch/i386/kernel/process.c, and makes arch/i386/kernel/signal.c use the
macro in place of its expansion.
This is a purely cosmetic cleanup for the normal i386 kernel. However, it

For prefetches of NULL (as when walking a short linked list), PPC64 will in

This patch adds detection of the Altivec capability of the CPU via the

It also fixes a problem where if a CPU isn't recognized as having altivec
features, and takes an altivec unavailable exception due to userland
issuing altivec instructions, the kernel would happily enable it and
context switch the registers ... but not all of them (it would basically
forget vrsave). With this patch, the kernel will refuse to enable altivec
when the feature isn't detected for the CPU (SIGILL).

This patch reworks the way the ppc64 is mapped in user memory by the kernel
to make it more robust against possible collisions with executable
segments. Instead of just whacking a VMA at 1Mb, I now use
get_unmapped_area() with a hint, and I moved the mapping of the vDSO to
after the mapping of the various ELF segments and of the interpreter, so
that conflicts get caught properly (it still has to be before
create_elf_tables since the later will fill the AT_SYSINFO_EHDR with the
proper address).
While I was at it, I also changed the 32 and 64 bits vDSO's to link at
their "natural" address of 1Mb instead of 0. This is the address where
they are normally mapped in absence of conflict. By doing so, it should be
possible to properly prelink one it's been verified to work on glibc.

This patch hacks the current PowerMac Alsa driver to add some basic support
of analog sound output to some desktop G5s. It has severe limitations
though:
- Only 44100Khz 16 bits
- Only work on G5 models using a TAS3004 analog code, that is early
single CPU desktops and all dual CPU desktops at this date, but none
of the more recent ones like iMac G5.
- It does analog only, no digital/SPDIF support at all, no native
AC3 support
Better support would require a complete rewrite of the driver (which I am
working on, but don't hold your breath), to properly support the diversity
of apple sound HW setup, including dual codecs, several i2s busses, all the
new codecs used in the new machines, proper clock switching with digital,
etc etc etc...
This patch applies on top of the other PowerMac sound patches I posted in
the past couple of days (new powerbook support and sleep fixes).
Note: This is a FAQ entry for PowerMac sound support with TI codecs: They
have a feature called "DRC" which is automatically enabled for the internal
speaker (at least when auto mute control is enabled) which will cause your
sound to fade out to nothing after half a second of playback if you don't
set a proper "DRC Range" in the mixer. So if you have a problem like that,
check alsamixer and raise your DRC Range to something reasonable.
Note2: This patch will also add auto-mute of the speaker when line-out jack
is used on some earlier desktop G4s (and on the G5) in addition to the
headphone jack. If that behaviour isn't what you want, just disable
auto-muting and use the manual mute controls in alsamixer.

The problem is that in do_settimeofday() we always set time_state to

To add support for 36-bit physical addressing on e500 the following changes
have been made. The changes are generalized to support any physical address
size larger than 32-bits:
* Allow FSL Book-E parts to use a 64-bit PTE, it is 44-bits of pfn, 20-bits
of flags.
* Introduced new CPU feature (CPU_FTR_BIG_PHYS) to allow runtime handling of
updating hardware register (SPRN_MAS7) which holds the upper 32-bits of
physical address that will be written into the TLB. This is useful since
not all e500 cores support 36-bit physical addressing.
* Currently have a pass through implementation of fixup_bigphys_addr
* Moved _PAGE_DIRTY in the 64-bit PTE case to free room for three additional
storage attributes that may exist in future FSL Book-E cores and updated
fault handler to copy these bits into the hardware TLBs.

While the existing pte_update code handled atomically modifying a 64-bit PTE,
it did not return all 64-bits of the PTE before it was modified. This causes
problems in some places that expect the full PTE to be returned, like
ptep_get_and_clear().
Created a new pte_update function that is conditional on CONFIG_PTE_64BIT. It
atomically reads the low PTE word which all PTE flags are required to be in
and returns a premodified full 64-bit PTE.
Since we now have an explicit 64-bit PTE version of pte_update we can also
remove the hack that existed to get the low PTE word regardless of size.

My previous patch that added sleep support for uninorth-agp and some AGP
"off" stuff in radeonfb and aty128fb is breaking some configs. More
specifically, it has problems with rage128 setups since the DRI code for
these in X doesn't properly re-enable AGP on wakeup or console switch
(unlike the radeon DRM).
This patch fixes the problem for pmac once for all by using a different
approach. The AGP driver "registers" special suspend/resume callbacks with
some arch code that the fbdev's can later on call to suspend and resume
AGP, making sure it's resumed back in the same state it was when suspended.
This is platform specific for now. It would be too complicated to try to
do a generic implementation of this at this point due to all sort of weird
things going on with AGP on other architectures. We'll re-work that whole
problem cleanly once we finally merge fbdev's and DRI.

This patch adds interrupt acknowledge to the PPC4xx PIC enable_irq
implementation for level-sensitive IRQ sources. This helps in cases when
enable/disable_irq is used in interrupt handlers for hardware, which
requires IRQ acknowledge to be issued from non-interrupt context (e.g.
when actual ACK in device needs an I2C transaction). For such strange
hardware, interrupt handler disables IRQ and defers actual ACK to some
other context. When this happens, IRQ is enabled again. For
level-sensitive sources we get spurious triggering right after IRQ is
enabled. This patch fixes this.
