      ARM: pm: let platforms select cpu_suspend support · 15e0d9e3
      由 Arnd Bergmann 提交于 
      Support for the cpu_suspend functions is only built-in
when CONFIG_PM_SLEEP is enabled, but omap3/4, exynos4
and pxa always call cpu_suspend when CONFIG_PM is enabled.

      ARM: vfp: use -mfloat-abi=soft to build vfp · 82b9c18d
      由 Arnd Bergmann 提交于 
      Distros are starting to ship with toolchains defaulting to
hardfloat. Using such a compiler to build the kernel fails
in the VFP directory with

arch/arm/vfp/entry.S:1:0: sorry, unimplemented: -mfloat-abi=hard and VFP

Adding -mfloat-abi=soft to the gcc command line fixes this.

      ARM: allow building alignment.c without PROC_FS · ffc660c5
      由 Arnd Bergmann 提交于 
      The two functions cpu_is_v6_unaligned and safe_usermode
are only defined when CONFIG_PROC_FS is enabled, but
are used outside of the #ifdef.

      ARM: always use ARM_UNWIND for thumb2 kernels · 89bace65
      由 Arnd Bergmann 提交于 
      Thumb2 kernels cannot be built with frame pointers, but can use the
ARM_UNWIND feature for unwinding instead. This makes sure that all
features that rely on unwinding includeing CONFIG_LATENCYTOP and
FAULT_INJECTION_STACKTRACE_FILTER do not enable frame pointers
when the unwinder is already selected, and we always build with
the unwinder when we want a thumb2 kernel, to make sure we do not
get the frame pointers instead.

A different option would be to redefine the CONFIG_FRAME_POINTERS
option on ARM to mean builing with either frame pointers or
the unwinder, and then select which one to use based on the
CPU architecture or another user option. That would still allow
building thumb2 kernels without the unwinder but would also be
more confusing.

      ARM: SMP depends on MMU · 9934ebb8
      由 Arnd Bergmann 提交于 
      The SMP implementation on ARM heavily depends on MMU-only code.
As long as nobody is interested in fixing this, let's disable the
SMP option when building for nommu.

      ARM: export rtc_lock for nvram driver · 63216d3c
      由 Arnd Bergmann 提交于 
      The rtc_lock is used by both the nvram and rtc drivers, so
we need to export it if at least one of the two is built,
not just for the rtc driver.
