cris: media platform drivers: fix build

2013-11-29T19:28:13+00:00

commit 72a0c5571351f5184195754d23db3e14495b2080 upstream.

On cris arch, the functions below aren't defined:

  drivers/media/platform/sh_veu.c: In function 'sh_veu_reg_read':

  drivers/media/platform/sh_veu.c:228:2: error: implicit declaration of function 'ioread32' [-Werror=implicit-function-declaration]

  drivers/media/platform/soc_camera/rcar_vin.c: In function 'rcar_vin_setup':
  drivers/media/platform/soc_camera/rcar_vin.c:284:3: error: implicit declaration of function 'iowrite32' [-Werror=implicit-function-declaration]

  drivers/media/platform/soc_camera/rcar_vin.c: In function 'rcar_vin_request_capture_stop':
  drivers/media/platform/soc_camera/rcar_vin.c:353:2: error: implicit declaration of function 'ioread32' [-Werror=implicit-function-declaration]

Yet, they're available, as CONFIG_GENERIC_IOMAP is defined.  What happens
is that asm/io.h was not including asm-generic/iomap.h.

Remove GENERIC_HARDIRQ config option

2013-09-13T13:09:52+00:00

After the last architecture switched to generic hard irqs the config
options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code
for !CONFIG_GENERIC_HARDIRQS can be removed.

arch: mm: pass userspace fault flag to generic fault handler

2013-09-12T22:38:01+00:00

Unlike global OOM handling, memory cgroup code will invoke the OOM killer
in any OOM situation because it has no way of telling faults occuring in
kernel context - which could be handled more gracefully - from
user-triggered faults.

Pass a flag that identifies faults originating in user space from the
architecture-specific fault handlers to generic code so that memcg OOM
handling can be improved.

CRIS: Remove last traces of legacy RTC drivers

2013-09-10T15:28:19+00:00

These legacy drivers were removed in commit
9c75fc8c5c8c50775fc8b89418219221335b758f ("CRIS: Remove legacy RTC
drivers"). Now remove their last traces in two Kconfig files and one

cris: delete __cpuinit usage from all cris files

2013-07-14T23:36:54+00:00

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
are flagged as __cpuinit  -- so if we remove the __cpuinit from
arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
content into no-ops as early as possible, since that will get rid
of these warnings.  In any case, they are temporary and harmless.

This removes all the arch/cris uses of the __cpuinit macros from
all C files.  Currently cris does not have any __CPUINIT used in
assembly files.
