6e8a0d11a0 sh: Make associative cache writes fatal on all SH-4A parts.
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.

a781d1e5ff sh: Drop associative writes for SH-4 cache flushes.
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.

2d4dc890b5 block: add helpers to run flush_dcache_page() against a bio and a request's 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.

d3ea9fa0a5 sh: Minor optimisations to FPU handling
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.

39ac11c160 sh: Improve performance of SH4 versions of copy/clear_user_highpage
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.

a0458b07c1 sh: add sleazy FPU optimization
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.

bb9074ff58 Merge commit 'v2.6.32-rc7'
Resolve the conflict between v2.6.32-rc7 where dn_def_dev_handler
gets a small bug fix and the sysctl tree where I am removing all
sysctl strategy routines.

1dca899e95 sh: dma: Kill off bogus dma_sysclass symbol export.
This is a static symbol, so the export is wholly superfluous. Recent
kbuild updates flagged this as an error, resulting in build failure,
so this tidies that up.

a09b6e8118 sysctl sh: Remove dead binary sysctl support
Now that sys_sysctl is a generic wrapper around /proc/sys  .ctl_name
and .strategy members of sysctl tables are dead code.  Remove them.

Also add an C99 named initializer to the child member of unaligned_root
to prevent chaos as the ctl_table definition changes over time.

3af539e59c sh64: Fix up reworked cache op build.
This gets the build fixed up for the sh64 cache enabled case.
Disabling still needs further abstraction for independent I/D-cache
disabling.

626ac8e138 sh64: Fix up the CONFIG_GENERIC_BUG=n build.
sh64 doesn't use GENERIC_BUG, which presently causes the handle_BUG()
code to blow up. Fix up the dependencies and get it all building again.

e9c58fc57b sh: Use the generic I/O port base for slowdown.
This fixes up the build and behaviour for various configurations. Namely
the CONFIG_32BIT cases where legacy mappings do not exist, as well as the
sh64 build.

a4d9d0b8a8 sh: Enable PMB support for all SH-4A CPUs.
Presently the PMB options were limited to a number of CPUs they were
tested with, but it is generally available on all SH-4A CPUs, so just
drop the subtype conditionals.
