      OMAP3 EVM: remove out-of-bounds array access of gpio_leds · ebe8f7e5
      由 Arnout Vandecappelle (Essensium/Mind) 提交于 
      Otherwise we can get the following warning on some compilers:

arch/arm/mach-omap2/board-omap3evm.c:384:11:
warning: array subscript is above array bounds

The omap3evm BSP enables a GPIO LED on the twl4030 chip.  However,
the static gpio_leds array doesn't have an entry for it.  This is
most likely a copy-and-paste error, because it has been in there
since the first commit of the omap3evm BSP (53c5ec31).

Reported-by: NAxel Lin <axel.lin@gmail.com>
Reported-by: NPeter Ujfalusi <peter.ujfalusi@ti.com>
(They both provided patches to fix it)

This patch also (at the request of the list) fixes the fact that
ARM has both LE and BE versions however the audit code was called as if
it was always BE.  If audit userspace were to try to interpret the bits
it got from a LE system it would obviously do so incorrectly.  Fix this
by using the right arch flag on the right system.

      ARM: OMAP: fix voltage domain build errors with PM_OPP disabled · 3ddd4d0c
      由 Russell King 提交于 
      The voltage domain code wants the voltage tables, which are in the
opp*.c files.  These files aren't built when PM_OPP is disabled,
causing the following build errors at link time:

      ARM/PCI: Remove ARM's duplicate definition of 'pcibios_max_latency' · e23e8c06
      由 Myron Stowe 提交于 
      The patch series to re-factor PCI's 'latency timer' setup (re:
http://marc.info/?l=linux-kernel&m=131983853831049&w=2) forgot to
remove the ARM specific definition of 'pcibios_max_latency' once such
had been moved into the pci core resulting in ARM related compile
errors -
  drivers/built-in.o:(.data+0x230): multiple definition of
  `pcibios_max_latency'
  arch/arm/common/built-in.o:(.data+0x40c): first defined here
  make[1]: *** [vmlinux.o] Error 1

In the series, patch 2/16 (commit 168c8619) converted the ARM
specific version of 'pcibios_set_master()' to a non-inlined version.
This was done in preperation for hosting it up into PCI's core, which
was done in patch 10/16 (commit 96c55900) of the series (and
where the removal of ARM's 'pcibios_max_latency' was overlooked).

      ARM: 7336/1: smp_twd: Don't register CPUFREQ notifiers if local timers are not initialised · 910ba598
      由 Santosh Shilimkar 提交于 
      Current ARM local timer code registers CPUFREQ notifiers even in case
the twd_timer_setup() isn't called. That seems to be wrong and
would eventually lead to kernel crash on the CPU frequency transitions
on the SOCs where the local timer doesn't exist or broken because of
hardware BUG. Fix it by testing twd_evt and *__this_cpu_ptr(twd_evt).

The issue was observed with v3.3-rc3 and building an OMAP2+ kernel
on OMAP3 SOC which doesn't have TWD.

Below is the dump for reference :

      ARM: OMAP: Fix build error when mmc_omap is built as module · d5171102

twl-common.c:(.text+0x108a0): undefined reference to

Fix this by warning about unusable MMC cover events.

The long term fix needs to change the MMC drivers to
register board specific callbacks directly with PMIC.

      ARM: OMAP: Fix kernel panic with HSMMC when twl4030_gpio is a module · 97899e55
      由 Tony Lindgren 提交于 
      On some omaps twl4030_gpio has a callback to try to initialize
the MMC controller. If twl4030_gpio is compiled as a module,
bad things can happen because the callback function starts
calling functions that are supposed to be marked __init:

Kernel panic - not syncing: Attempted to kill the idle task!
twl4030_gpio twl4030_gpio: can't dispatch IRQs from modules
gpiochip_add: registered GPIOs 192 to 209 on device: twl4030
Unable to handle kernel paging request at virtual address b82a4c74
...

Additionally if this does not fail, warnings are produced
about trying to register the MMC multiple times.

Fix this by removing __init from omap_mux_get_by_name,
and add checks if omap2_hsmmc_init() is getting called more
than once.

Note that this will get fixed properly later on by splitting
omap2_hsmmc_init into two functions.
