2013-04-17ARM: ARMv7-M: Add support for exception handlingUwe Kleine-König3-0/+271
This patch implements the exception handling for the ARMv7-M architecture (pretty different from the A or R profiles). It bases on work done earlier by Catalin for 2.6.33 but was nearly completely rewritten to use a pt_regs layout compatible to the A profile.

2013-04-17ARM: Add base support for ARMv7-MCatalin Marinas16-21/+407
This patch adds the base support for the ARMv7-M architecture. It consists of the corresponding arch/arm/mm/ files and various #ifdef's around the kernel. Exception handling is implemented by a subsequent patch. [ukleinek: squash in some changes originating from commit b5717ba (Cortex-M3: Add support for the Microcontroller Prototyping System) from the v2.6.33-arm1 patch stack, port to post 3.6, drop zImage support, drop reorganisation of pt_regs, assert CONFIG_CPU_V7M doesn't leak into installed headers and a few cosmetic changes] Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Reviewed-by: Jonathan Austin <jonathan.austin@arm.com> Tested-by: Jonathan Austin <jonathan.austin@arm.com> Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

Only the fbdev/framebuffer piece remains now that the SCSI stuff has gone in. Here are the UAPI disintegration bits for the fbdev drivers. It appears that Florian hasn't had time to deal with my patch, but back in December he did say he didn't mind if I pushed it forward." Yay. No more uapi movement.

But, I'd really like to get it out to a broader audience to hammer out any performance issues or other problems. scrub does not yet correct errors on raid5/6 either. Josef has another pass at fsync performance. The big change here is to combine waiting for metadata with waiting for data, which is a big latency win. It is also step one toward using atomics from the hardware during a commit. Mark Fasheh has a new way to use btrfs send/receive to send only the metadata changes. SUSE is using this to make snapper more efficient at finding changes between snapshosts. Snapshot-aware defrag is also included. Otherwise we have a large number of fixes and cleanups.

2013-03-03ext4: don't allow quota mount options when quota feature enabledJan Kara1-7/+26
So far we silently ignored when quota mount options were set while quota feature was enabled. But this can create confusion in userspace when mount options are set but silently ignored and also creates opportunities for bugs when we don't properly test all quota types. Actually ext4_mark_dquot_dirty() forgets to test for quota feature so it was dependent on journaled quota options being set. OTOH ext4_orphan_cleanup() tries to enable journaled quota when quota options are specified which is wrong when quota feature is enabled.

Metag does not use dma_map_ops yet, hence it should implement it as an inline stub using dma_common_get_sgtable().

2013-03-03metag: copy devicetree to non-init memoryJames Hogan3-0/+20
Make a copy of the device tree blob in non-init memory. It is required when using built-in device tree files that the platform code copies the blob to non-init memory prior to calling unflatten_device_tree(), otherwise the strings that the device tree refer to will get poisoned and potentially reused, breaking later reading of the device tree post-init (such as compatible matching in modules, debugfs, and the procfs interface).

2013-03-03metag: move irq enable out of irqflags.h on SMPJames Hogan2-7/+20
The SMP version of arch_local_irq_enable() uses preempt_disable(), but <asm/irqflags.h> doesn't include <linux/preempt.h> causing the following errors on SMP when pstore/ftrace is enabled (caught by buildbot smp allyesconfig): In file included from include/linux/irqflags.h:15, from fs/pstore/ftrace.c:16: arch/metag/include/asm/irqflags.h: In function 'arch_local_irq_enable': arch/metag/include/asm/irqflags.h:84: error: implicit declaration of function 'preempt_disable' arch/metag/include/asm/irqflags.h:86: error: implicit declaration of function 'preempt_enable_no_resched' However <linux/preempt.h> cannot be easily included from <asm/irqflags.h> as it can cause circular include dependencies in the !SMP case, and potentially in the SMP case in the future. Therefore move the SMP implementation of arch_local_irq_enable() into traps.c and use an inline version of get_trigger_mask() which is also defined in traps.c for SMP. This adds an extra layer of function call / stack push when preempt_disable needs to call other functions, however in the non-preemptive SMP case it should be about as fast, as it was already calling the get_trigger_mask() function which is now used inline.

2013-03-03genksyms: fix metag symbol prefix on crc symbolsJames Hogan1-1/+2
Meta uses symbol prefixes, so add "metag" to the list of architectures to set the mod_prefix to "_" for. This fixes __crc_* symbols to add the extra underscore to match _CRC_SYMBOL macro in <linux/export.h> and so that modpost finds them. Signed-off-by: James Hogan <james.hogan@imgtec.com>
