2009-12-14locking: Convert raw_spinlock to arch_spinlockThomas Gleixner
The raw_spin* namespace was taken by lockdep for the architecture specific implementations. raw_spin_* would be the ideal name space for the spinlocks which are not converted to sleeping locks in preempt-rt. Linus suggested to convert the raw_ to arch_ locks and cleanup the name space instead of using an artifical name like core_spin, atomic_spin or whatever No functional change.

2009-12-04sh: Make associative cache writes fatal on all SH-4A parts.Paul Mundt
Now that associative cache writes are no longer needed by the SH-4/SH-4A cache flush code, associative write support can be explicitly disabled for all SH-4A parts. This makes any associative write throw an exception, as this behaviour can not be assumed to exist on future parts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-12-04sh: Drop associative writes for SH-4 cache flushes.Matt Fleming
When flushing/invalidating the icache/dcache via the memory-mapped IC/OC address arrays, the associative bit should only be used in conjunction with virtual addresses. However, we currently flush cache lines based on physical address, so stop using the associative bit. It is a better strategy to use non-associative writes (and physical tags) for flushing the caches anyway, because flushing by virtual address (as with the A-bit set) requires a valid TLB entry for that virtual address. If one does not exist in the TLB no exception is generated and the flush is silently ignored. This is also future-proofing for SH-4A parts which are gradually phasing out associative writes to the cache array due to the aforementioned case of certain flushes silently turning in to nops.

2009-11-26block: add helpers to run flush_dcache_page() against a bio and a request's ↵Ilya Loginov
pages Mtdblock driver doesn't call flush_dcache_page for pages in request. So, this causes problems on architectures where the icache doesn't fill from the dcache or with dcache aliases. The patch fixes this. The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid pointless empty cache-thrashing loops on architectures for which flush_dcache_page() is a no-op. Every architecture was provided with this flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is equal 1 or do nothing otherwise. See "fix mtd_blkdevs problem with caches on some architectures" discussion on LKML for more information.

2009-11-24sh: Minor optimisations to FPU handlingStuart Menefy
A number of small optimisations to FPU handling, in particular: - move the task USEDFPU flag from the thread_info flags field (which is accessed asynchronously to the thread) to a new status field, which is only accessed by the thread itself. This allows locking to be removed in most cases, or can be reduced to a preempt_lock(). This mimics the i386 behaviour. - move the modification of regs->sr and thread_info->status flags out of save_fpu() to __unlazy_fpu(). This gives the compiler a better chance to optimise things, as well as making save_fpu() symmetrical with restore_fpu() and init_fpu(). - implement prepare_to_copy(), so that when creating a thread, we can unlazy the FPU prior to copying the thread data structures. Also make sure that the FPU is disabled while in the kernel, in particular while booting, and for newly created kernel threads, In a very artificial benchmark, the execution time for 2500000 context switches was reduced from 50 to 45 seconds.

2009-11-24sh: Improve performance of SH4 versions of copy/clear_user_highpageStuart Menefy
The previous implementation of clear_user_highpage and copy_user_highpage checked to see if there was a D-cache aliasing issue between the user and kernel mappings of a page, but if there was they always did a flush with writeback on the dirtied kernel alias. However as we now have the ability to map a page into kernel space with the same cache colour as the user mapping, there is no need to write back this data. Currently we also invalidate the kernel alias as a precaution, however I'm not sure if this is actually required. Also correct the definition of FIX_CMAP_END so that the mappings created by kmap_coherent() are actually at the correct colour.

2009-11-24sh: add sleazy FPU optimizationGiuseppe CAVALLARO
sh port of the sLeAZY-fpu feature currently implemented for some architectures such us i386. Right now the SH kernel has a 100% lazy fpu behaviour. This is of course great for applications that have very sporadic or no FPU use. However for very frequent FPU users... you take an extra trap every context switch. The patch below adds a simple heuristic to this code: after 5 consecutive context switches of FPU use, the lazy behavior is disabled and the context gets restored every context switch. After 256 switches, this is reset and the 100% lazy behavior is returned. Tests with LMbench showed no regression. I saw a little improvement due to the prefetching (~2%). The tests below also show that, with this sLeazy patch, indeed, the number of FPU exceptions is reduced. To test this. I hacked the lat_ctx LMBench to use the FPU a little more. sLeasy implementation =========================================== switch_to calls | 79326 sleasy calls | 42577 do_fpu_state_restore calls| 59232 restore_fpu calls | 59032 Exceptions: 0x800 (FPU disabled ): 16604 100% Leazy (default implementation) =========================================== switch_to calls | 79690 do_fpu_state_restore calls | 53299 restore_fpu calls | 53101 Exceptions: 0x800 (FPU disabled ): 53273 Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: Stuart Menefy <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
