* ARM: convert all "mov.* pc, reg" to "bx reg" for ARMv6+Russell King2014-07-181-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARMv6 and greater introduced a new instruction ("bx") which can be used to return from function calls. Recent CPUs perform better when the "bx lr" instruction is used rather than the "mov pc, lr" instruction, and this sequence is strongly recommended to be used by the ARM architecture manual (section A.4.1.1). We provide a new macro "ret" with all its variants for the condition code which will resolve to the appropriate instruction. Rather than doing this piecemeal, and miss some instances, change all the "mov pc" instances to use the new macro, with the exception of the "movs" instruction and the kprobes code. This allows us to detect the "mov pc, lr" case and fix it up - and also gives us the possibility of deploying this for other registers depending on the CPU selection.

* arm: delete __cpuinit/__CPUINIT usage from all ARM usersPaul Gortmaker2013-07-141-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related 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 ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.

* ARM: mm: implement LoUIS API for cache maintenance opsLorenzo Pieralisi2012-09-251-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARM v7 architecture introduced the concept of cache levels and related control registers. New processors like A7 and A15 embed an L2 unified cache controller that becomes part of the cache level hierarchy. Some operations in the kernel like cpu_suspend and __cpu_disable do not require a flush of the entire cache hierarchy to DRAM but just the cache levels belonging to the Level of Unification Inner Shareable (LoUIS), which in most of ARM v7 systems correspond to L1. The current cache flushing API used in cpu_suspend and __cpu_disable, flush_cache_all(), ends up flushing the whole cache hierarchy since for v7 it cleans and invalidates all cache levels up to Level of Coherency (LoC) which cripples system performance when used in hot paths like hotplug and cpuidle. Therefore a new kernel cache maintenance API must be added to cope with latest ARM system requirements. This patch adds flush_cache_louis() to the ARM kernel cache maintenance API. This function cleans and invalidates all data cache levels up to the Level of Unification Inner Shareable (LoUIS) and invalidates the instruction cache for processors that support it (> v7). This patch also creates an alias of the cache LoUIS function to flush_kern_all for all processor versions prior to v7, so that the current cache flushing behaviour is unchanged for those processors. v7 cache maintenance code implements a cache LoUIS function that cleans and invalidates the D-cache up to LoUIS and invalidates the I-cache, according to the new API.

| | | | | | | | | | | | | | | | | The cacheflush syscall can fail for two reasons: (1) The arguments are invalid (nonsensical address range or no VMA) (2) The region generates a translation fault on a VIPT or PIPT cache This patch allows do_cache_op to return an error code to userspace in the case of the above. The various coherent_user_range implementations are modified to return 0 in the case of VIVT caches or -EFAULT in the case of an abort on v6/v7 cores.

| | | | | | | | | | | | | Commit 66a625a (ARM: mm: proc-macros: Add generic proc/cache/tlb struct definition macros) introduced build errors when PM_SLEEP is not enabled. The per-CPU do_suspend/do_resume functions are defined via the preprocessor to constant 0. However, the macros which use these were converted to assembly, resulting in undefined references to these functions. Fix that by moving the ! ifdef section into proc-macros.S and deleting it from all effected proc-*.S files.

Enabling the data cache without the MMU is an invalid combination. However, there are CPUs where the data cache can be enabled without the MMU. In order to allow these CPUs to take advantage of that, provide a method whereby each proc-*.S file defines the control regsiter value for use with nommu (with the MMU disabled.) Later on, when we add support for enabling the MMU on these devices, we can adjust the "crval" macro to also enable the data cache for nommu. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
