9a6b344ea9 x86: remove long dead cyrix mtrr code
cyrix_arr_init was #if 0 all the way back to at least v2.6.12.

This was the only place where arr3_protected was set to anything
but zero.  Eliminate this variable.

f0be6c6a69 x86 setup: print missing CPU features in cleartext
Instead of obscure numbers, print the list of missing CPU features in
cleartext.  To conserve space, use a host program (mkcpustr.c) to

84fb144b92 x86: reintroduce volatile keyword in prototype to clflush()
The volatile keyword was removed from the clflush() prototype
in commit e34907ae180f4fe6c28bb4516c679c2f81b0c9ed; the comment there
states:

    x86: remove volatile keyword from clflush.

    the p parameter is an explicit memory reference, and is
    enough to prevent gcc to being nasty here. The volatile
    seems completely not needed.

This reflects incorrect understanding of the function of the volatile
keyword there.  The purpose of the volatile keyword is informing gcc
that it is safe to pass a volatile pointer to this function.

2347d933b1 x86: cpuid: allow querying %ecx-sensitive CPUID levels
After /dev/*/cpuid was introduced, Intel changed the semantics of the
CPUID instruction to be sentitive to %ecx as well as %eax.  This patch
allows querying of %ecx-sensitive levels by placing the %ecx value in
the upper 32 bits of the file position (lower 32 bits always were used
for the %eax value.)

The apm module were renamed to apm_32 during the merge of 32 and 64 bit
x86 which is unfortunate. As apm is 32 bit specific we like to keep the
_32 in the filename but the module should be named apm.

Fix this in the Makefile.

      x86: fix ioremap RAM check

this check was too strict and caused an ioremap() failure.

the problem is due to the somewhat unclean way of how the GART code
reserves a memory range for its aperture, and how it utilizes it
later on.

Allow RAM pages to be ioremap()-ed too, as long as they are reserved.

4cd9d6f774 [ARM] 4736/1: Export atags to userspace and allow kexec to use customised atags
Currently, the atags used by kexec are fixed to the ones originally used
to boot the kernel. This is less than ideal as changing the commandline,
initrd and other options would be a useful feature.

This patch exports the atags used for the current kernel to userspace
through an "atags" file in procfs. The presence of the file is
controlled by its own Kconfig option and cleans up several ifdef blocks
into a separate file. The tags for the new kernel are assumed to be at
a fixed location before the kernel image itself. The location of the
tags used to boot the original kernel is unimportant and no longer
saved.

fa3218d859 [ARM] 4660/3: at91: allow selecting UART for early kernel messages
Currently early kernel messages, i.e., those from uncompression, go to the
debugging UART. And if it is enabled in the platform configuration, but
not initialized by the bootloader, the machine hangs, waiting for UART
status change. Besides, having those messages on another UART - typically
the console UART - may be preferrable. This patch allows selecting the
UART in kernel configuration.

e83aff58bf [ARM] 4739/1: at91sam9263: make gpio bank C and D irqs work
On the at91sam9263, IRQs for GPIO banks C and D don't currently work.
This is because banks C, D, and E share one clock and toplevel IRQ, but
the AT91 code setting up and handling GPIO IRQs expects no sharing.
This patch:

 - Fixes GPIO IRQ setup and handling to cope with GPIO banks that are
   shared like on sam9263 chips, by setting up a list of those banks
   and making the IRQ dispatching logic scan that list.

 - Precomputes the address of each bank's registers, saving it with
   other per-bank data so that it no longer needs to be constantly
   recomputed during IRQs and other GPIO operations.  That shrinks
   hot-path code, while helping the GPIO bank irq updates.

 - Fixes a minor bug where IRQ_TYPE_NONE was wrongly rejected (it just
   means "use the default", which is "both edges" here).

43816bcb72 [ARM] 4809/2: ixp4xx: Merge dsmg600-power.c into dsmg600-setup.c
There is no reason to have power control in a separate file from the
board setup code.  Merge it back into the board setup file and remove
superfluous header includes.

b7edc84a96 [ARM] 4806/1: ixp4xx: Ethernet support for the nslu2 and nas100d boards
Enables the new ixp4xx qmgr and npe drivers in ixp4xx_defconfig.

Sets up the corresponding platform data for the nslu2 and nas100d
boards, and reads the ethernet MAC address from the internal flash.

Tested on both little-endian and big-endian kernels.
