* sh64: Fix up reworked cache op build.Paul Mundt2009-11-121-1/+1
| | | | | | | | This gets the build fixed up for the sh64 cache enabled case. Disabling still needs further abstraction for independent I/D-cache disabling. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* Revert "sh: Kill off now redundant local irq disabling."Paul Mundt2009-09-011-6/+23
| | | | | | | | | | | This reverts commit 64a6d72213dd810dd55bd0a503c36150af41c3c3. Unfortunately we can't use on_each_cpu() for all of the cache ops, as some of them only require preempt disabling. This seems to be the same issue that impacts the mips r4k caches, where this code was based on. This fixes up a deadlock that showed up in some IRQ context cases.

* sh: Kill off now redundant local irq disabling.Paul Mundt2009-08-211-23/+6
| | | | | | | on_each_cpu() takes care of IRQ and preempt handling, the localized handling in each of the called functions can be killed off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Make cache flushers SMP-aware.Paul Mundt2009-08-211-23/+41
| | | | | | | | This does a bit of rework for making the cache flushers SMP-aware. The function pointer-based flushers are renamed to local variants with the exported interface being commonly implemented and wrapping as necessary. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh64: Kill off dead i/d-cache disabled bits.Paul Mundt2009-08-161-12/+0
| | | | | | | These will be handled through the shared cache interface instead, and they are presently undefined anyways. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix up the SH-5 build with caches enabled.Paul Mundt2009-08-161-228/+21

* sh: Migrate SH-4 cacheflush ops to function pointers.Paul Mundt2009-08-151-0/+4
| | | | | | | | | | This paves the way for allowing individual CPUs to overload the individual flushing routines that they care about without having to depend on weak aliases. SH-4 is converted over initially, as it wires up pretty much everything. The majority of the other CPUs will simply use the default no-op implementation with their own region flushers wired up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off unused flush_icache_user_range().Paul Mundt2009-08-151-1/+1
| | | | | | | | We use flush_cache_page() outright in copy_to_user_page(), and nothing else needs it, so just kill it off. SH-5 still defines its own version, but that too will go away in the same fashion once it converts over. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Centralize the CPU cache initialization routines.Paul Mundt2009-08-151-1/+1
| | | | | | | | This provides a central point for CPU cache initialization routines. This replaces the antiquated p3_cache_init() method, which the vast majority of CPUs never cared about. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Provide the kmap_coherent() interface generically.Paul Mundt2009-08-151-0/+15
| | | | | | | | | This plugs in kmap_coherent() for the non-SH4 cases to permit the pg-mmu.c bits to be used generically across all CPUs. SH-5 is still in the TODO state, but will move over to fixmap and the generic interface gradually. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh64: Wire up the shared __flush_xxx_region() flushers.Paul Mundt2009-08-151-48/+0
| | | | | | | | Now with all of the prep work out of the way, kill off the SH-5 variants and use the SH-4 version directly. This also takes advantage of the unrolling that was previously done for the new version. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Use the now generic SH-4 clear/copy page ops for all MMU platforms.Paul Mundt2009-07-271-0/+17
| | | | | | | | | | | | Now that the SH-4 page clear/copy ops are generic, they can be used for all platforms with CONFIG_MMU=y. SH-5 remains the odd one out, but it too will gradually be converted over to using this interface. SH-3 platforms which do not contain aliases will see no impact from this change, while aliasing SH-3 platforms will get the same interface as SH-4. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Get SH-5 caches working again post-unification.Paul Mundt2008-02-141-610/+411
| | | | | | | A number of cleanups to get the SH-5 cache management code in line with the rest of the SH backend. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Update SH-5 flush_cache_sigtramp() for API changes.Paul Mundt2008-02-141-3/+5
| | | | | | | | Previously this took an explicit range, update this to use the same behaviour as the rest of the SH parts where we simply flush out a line from the start address. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
