sh: use printk_ratelimited instead of printk_ratelimit

2011-06-30T06:10:06+00:00

Follows the powerpc change, for much the same rationale.

sh: fix wrong icache/dcache address-array start addr in cache-debugfs.

2011-06-06T03:30:02+00:00

This patch fixes a icache/dcache address-array start address while
dumping its entires in debugfs. Perviously the code was attempting to
remember the address in static variable, which is no more required
for debugfs, as the function can be executed in one pass.

Without this patch the start address ends up in wrong place and the
/sys/kernel/debug/sh/icache or dcache debugfs contents may not be correct.

sh64: Move from P1SEG to CAC_ADDR for consistent sync.

2011-05-31T05:38:29+00:00

sh64 doesn't define a P1SEGADDR, resulting in a build failure. The proper
mapping can be attained for both sh32 and 64 via the CAC_ADDR macro, so
switch to that instead.

sh: pmb: Use struct syscore_ops instead of sysdevs

2011-03-23T10:05:18+00:00

This converts the PMB code over to use the new syscore_ops and kills off
the old sysdev utilization, as per Rafael's example.

sh: Enable CONFIG_GCOV_PROFILE_ALL for sh

2011-02-15T07:47:17+00:00

This patch enables gcov kernel profiling over the whole kernel for sh.
Profiling of specific files individually already worked. A handful of
files have to be explicitly excluded from the profiling to avoid
breaking things, notably pmb.c.

sh: Flush executable pages in copy_user_highpage

2011-02-15T07:24:31+00:00

This resolves a problem seen when using the Android dynamic linker.
Sometimes the dynamic linker would seg-fault at start up and this
was eventually traced to the handling of a COW fault for a page which
was being modified by the linker. If there was no cache aliasing between
the kernel and the user page, the page was not flushed, leaving the
newly copied data in the D-cache. However when executing instructions
from that page, the I-cache is filled directly from external memory,
rather than the D-cache, and causing garbage to be executed.

thp: pte alloc trans splitting

2011-01-14T01:32:40+00:00

pte alloc routines must wait for split_huge_page if the pmd is not present
and not null (i.e.  pmd_trans_splitting).  The additional branches are
optimized away at compile time by pmd_trans_splitting if the config option
is off.  However we must pass the vma down in order to know the anon_vma
lock to wait for.

reservations through memblock.
