dccaad8950 OMAP3: PM: Force write last pad config register into save area
Due to OMAP3 erratas 1.157, 1.185 the save of the last pad register
(ETK_D14 and ETK_D15) can fail sometimes when there is simultaneous
OCP access to the SCM register area. Fixed by writing the last
register to the save area.

Also, optimized the delay loop for the HW save to include an udelay(1),
which limits the number of unnecessary HW accesses to SCM register area
during the save.

8640425b26 OMAP3: PM: Removing redundant and potentially dangerous PRCM configration
As part of Core domain context restoration while coming out of off mode
there are some registers being restored which are not required to be restored.
ROM code will have restored them already. Overwriting some of them can have
potential side effect. Eg: CM_CLKEN_PLL register should not be written while dpll is locked.
Tested on OMAP 3430 SDP for suspend/resume and off mode with sleep_while_idle enabled.

f18cc2ff5e OMAP3: PM: Disable interrupt controller AUTOIDLE before WFI
OMAP interrupt controller goes to unknown state when there is right
combination of l3,l4 sleep/wake-up transitions, l4 autoidle in
interrupt controller and some interrupt. When this happens, interrupts
are not delivered to ARM anymore and ARM will remain in WFI (wait for
interrupt) until interrupt controller is forced to wake-up
(i.e. lauterbach).

682137f7e6 m68knommu: fix definitions of __pa() and __va()
Fix compilation breakage of all m68knommu targets:

  CC      arch/m68knommu/kernel/asm-offsets.s
In file included from include/linux/sched.h:77,
                 from arch/m68knommu/kernel/asm-offsets.c:12:
include/linux/percpu.h: In function 'per_cpu_ptr_to_phys':
include/linux/percpu.h:161: error: implicit declaration of function 'virt_to_phy

This is broken in linux-2.6.33-rc3.

Change the definitions of __pa() and __va() to not use virt_to_phys()
and phys_to_virt(). Trivial 1:1 conversion required for the non-MMU case.

A side effect if this is that the m68knommu can now use asm/virtconvert.h
for the definition of virt_to_phys() and phys_to_virt().

Also cleaned up the definition of page_to_phys() when moving into
virtconvert.h.

a2342f4643 sata_promise: don't classify overruns as HSM errors
When sata_promise encounters an overrun or underrun error it
translates that to a libata AC_ERR_HSM, causing a hard reset.
Since over/under-runs were thought to be rare and transient,
this action seemed reasonable.

Unfortunately it turns out that the controller throws overrun
errors when e.g. hal polls a CD or DVD writer containing blank
media, causing long sequences of hard resets and retries before
EH finally gives up.

This patch updates sata_promise to classify over/under-runs as
AC_ERR_OTHER instead. This allows libata EH and upper layers to
retry or fail the operation as they see fit without the disruption
caused by repeated hard resets.

This fixes a problem using a DVD-RAM drive with sata_promise,
reported by Thomas Schorpp. I also tested it on a DVD-RW drive.

Since commit 898d357b5262f9e26bc2418e01f8676e80d9867e (lmo) /
6acc7d485c (kernel.org) ("Fix and enhance
built-in kernel command line") arcs_cmdline[] does not contain built-in
command line.  The commit introduce CONFIG_CMDLINE_BOOL and
CONFIG_CMDLINE_OVERRIDE to control built-in command line, and now we can
use them instead of platform-specific built-in command line processing.

2620c3570f MIPS: PowerTV: Remove mips_machine_halt()
mips_machine_halt() is same as mips_machine_restart().  Also delete the
registration of _machine_halt and pm_power_off because mips_machine_halt()
is the restart function.

sizeof(dp) is just the size of the pointer.  Change it to the size of the

d4d9a553d7 MIPS: Cleanup and Fixup of compressed kernel support
o Remove the .initrd section.  The initrd section was already handled
   when vmlinux was linked.
 o Discard .MIPS.options, .options, .pdr, .reginfo, .comment and .note
   sections.  If .MIPS.options is not removed, kernels compiled with gcc
   3.4.6 will not boot.
 o Clean up the file format.
 o Remove several other unneeded sections.

Tested with GCC 3.4.6 and 4.4.1 with and without initrd.
