1befdd5536 MIPS: Implement __read_mostly
Just do what everyone else is doing by placing __read_mostly things in
the .data.read_mostly section.

mips_io_port_base can not be read-only (const) and writable
(__read_mostly) at the same time.  One of them has to go, so I chose
to eliminate the __read_mostly.  It will still get stuck in a portion
of memory that is not adjacent to things that are written, and thus
not be on a dirty cache line, for whatever that is worth.

f5b35d0b16 MIPS: ath79: add common WMAC device for AR913X based boards
Add common platform_device and helper code to make the registration
of the built-in wireless MAC easier on the Atheros AR9130/AR9132
based boards. Also register the WMAC device on the AR81 board.

d4a67d9dc8 MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCs
This patch adds initial support for various Atheros SoCs based on the
MIPS 24Kc core. The following models are supported at the moment:

  - AR7130
  - AR7141
  - AR7161
  - AR9130
  - AR9132
  - AR7240
  - AR7241
  - AR7242

The current patch contains minimal support only, but the resulting
kernel can boot into user-space with using of an initramfs image on
various boards which are using these SoCs. Support for more built-in
devices and individual boards will be implemented in further patches.

8d662c8d34 MIPS: Use WARN() in uasm for better diagnostics.
On the off chance that uasm ever warns about overflow, there is no way
to know what the offending instruction is.

Change the printks to WARNs, so we can get a nice stack trace.  It has
the added benefit of being much more noticeable than the short single
line warning message, so is less likely to be ignored.

487d70d0b8 MIPS: Add generic support for multiple machines within a single kernel
This patch adds a generic solution to support multiple machines based on
a given SoC within a single kernel image. It is implemented already for
several other architectures but MIPS has no generic support for that yet.

[Ralf: This competes with DT but DT is a much more complex solution and this
code has been used by OpenWRT for a long time so for now DT is a bad reason
to stop the merge but longer term this should be migrated to DT.]

used to be the case before we reorganized the layout for hotplug cpu,
as we used to fall through to __error.  With the changed layout, we
need an explicit branch here instead.

ee309d3d6e ARM: mmp: MMP2 drive strength FAST using wrong value
Drive strength for MMP2 is a 2 bit value but because of the mapping in
plat-pxa/mfp.h needs to be shifted up one bit to handle real
location in mfp registers.  (MMP2 and PXA910 drive strength start
at bit 11 while PXA168 starts at bit 10).

Values 0, 1, 2, and 3 effectively need to be
0, 2, 4, and 6 to fit into register.  8 does not work.

d5996b2ff0 ARM: fix /proc/$PID/stack on SMP
Rabin Vincent reports:
| On SMP, this BUG() in save_stack_trace_tsk() can be easily triggered
| from user space by reading /proc/$PID/stack, where $PID is any pid but
| the current process:
|
|	if (tsk != current) {
| #ifdef CONFIG_SMP
|		/*
|		 * What guarantees do we have here that 'tsk'
|		 * is not running on another CPU?
|		 */
|		BUG();
| #else

Fix this by replacing the BUG() with an entry to terminate the stack
trace, returning an empty trace - I'd rather not expose the dwarf
unwinder to a volatile stack of a running thread.

671289c287 ARM: Fix build regression on SA11x0, PXA, and H720x targets
Build errors similar this appeared in todays kautobuild for the above
targets:

In file included from arch/arm/include/asm/pgtable.h:461,
                 from arch/arm/mach-pxa/generic.c:26:
include/asm-generic/pgtable.h: In function 'ptep_test_and_clear_young':
include/asm-generic/pgtable.h:29: error: dereferencing pointer to incomplete type

None of the .c files including asm/pgtable.h with this error is using
this header, so simply remove the include.

This reverts commit dfe63bb0ad.

This commit was causing nouveau not to work properly, for -rc1 I'd
prefer it worked and we can look if this is useful for 2.6.39.
