      ARM: common/vic: use proper __iomem annotations · d4f3add2
      Arnd Bergmann authored 
      In vic_init, we pass addr into readl, so it needs to be a
pointer, not a u32 address.

      ARM: OC_ETM should not select ARM_AMBA · 53eebb0d
      Arnd Bergmann authored 
      The CONFIG_ARM_AMBA symbol is selected by the platforms that support
AMBA, and the other platforms (e.g. orion) might not be able to
build that code at all when they do not support the clk API.

Instead, make sure that OC_ETM is only built on platforms that
do support the amba subsystem already.

      ARM: pci: always export pcibios_bus_to_resource · b214bea5
      Arnd Bergmann authored 
      Some PCI drivers call pcibios_bus_to_resource directly,
but it is only exported when CONFIG_HOTPLUG is set,
because it was initially mean for pccard support.

Moving the export out of the #ifdef lets us avoid these
build errors:

ERROR: "pcibios_bus_to_resource" [drivers/video/vt8623fb.ko] undefined!
ERROR: "pcibios_bus_to_resource" [drivers/video/arkfb.ko] undefined!
ERROR: "pcibios_bus_to_resource" [drivers/video/s3fb.ko] undefined!

      ARM: add io{read,write}{16,32}be functions · 06901bd8
      Arnd Bergmann authored 
      These functions are used in some PCI drivers with big-endian
MMIO space, and they are trivial to add here.

      ARM: limit CONFIG_HAVE_IDE to platforms that do · d0ee9f40
      Arnd Bergmann authored 
      Support for IDE drivers should not be automatic, since most platforms
cannot actually support any IDE low-level drivers. This partly
reverts 2064c946 "ARM: always select HAVE_IDE" to set this symbol
only when either a PC-style bus (PCI, ISA, PCMCIA) is enabled or
a platform is used that is known to have an existing driver in
drivers/ide.

New platforms should not need this option and just use CONFIG_ATA
with drivers/ata/.

      ARM: pm: let platforms select cpu_suspend support · 15e0d9e3
      Arnd Bergmann authored 
      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
      Arnd Bergmann authored 
      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
      Arnd Bergmann authored 
      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
      Arnd Bergmann authored 
      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
      Arnd Bergmann authored 
      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
      Arnd Bergmann authored 
      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.
