sh: Fix up SH4-202 clkfwk build.

2010-12-24T02:27:29+00:00

Some of the SH4-202 code was overlooked in the set_rate() API conversion,
resulting in:

arch/sh/kernel/cpu/sh4/clock-sh4-202.c: error: too many arguments to function 'clk->ops->set_rate'

Fix it up.

sh: clkfwk: Kill off now unused algo_id in set_rate op.

2010-11-15T09:25:17+00:00

Now that clk_set_rate_ex() is gone, there is also no way to get at rate
setting algo id, which is now also completely unused. Kill it off before
new clock ops start using it.

sh: oprofile: Fix up and extend op_name_from_perf_id().

2010-10-27T07:51:33+00:00

op_name_from_perf_id() currently returns a local variable, which isn't
terribly productive. As we only handle a single PMU case for now, simply
allocate and free the string from the arch init/exit context and have
op_name_from_perf_id() hand back the cached string.

This also takes UTS_MACHINE in to account, given that we build for
multiple architectures.

sh: change PVR of SH7757 for 2nd cut

2010-07-06T08:37:57+00:00

All 1st cut silicon in the wild has been replaced by the 2nd cut, so it's
safe to replace all of the 1st cut references and support.

sh: switch sh4-202 to clkdev

2010-05-13T08:37:59+00:00

This patch converts the remaining sh4-202 clocks
to use clkdev for lookup. The now unused name
and id from struct clk are also removed.

sh: Tidy CPU probing and fixup section annotations.

2010-04-21T03:01:06+00:00

This does a detect_cpu_and_cache_system() -> cpu_probe() rename, tidies
up the unused return value, and stuffs it under __cpuinit in preparation
for CPU hotplug.

sh: Kill off timer clock strings for legacy CPG parts.

2010-03-29T08:25:03+00:00

Now with the lookup aliases in place there is no longer any need to
provide the clock string, kill it off for all legacy CPG CPUs.

sh: Kill off all timer name clobbering.

2010-03-10T07:28:16+00:00

Now that dev_name() can be used early, we no longer require a static
string. Kill off all of the superfluous timer names.

Driver core: Constify struct sysfs_ops in struct kobj_type

2010-03-08T01:04:49+00:00

Constify struct sysfs_ops.

This is part of the ops structure constification
effort started by Arjan van de Ven et al.

Benefits of this constification:

 * prevents modification of data that is shared
   (referenced) by many other structure instances
   at runtime

 * detects/prevents accidental (but not intentional)
   modification attempts on archs that enforce
   read-only kernel data at runtime

 * potentially better optimized code as the compiler
   can assume that the const data cannot be changed

 * the compiler/linker move const data into .rodata
   and therefore exclude them from false sharing

sh: Fix up more 64-bit pgprot truncation on SH-X2 TLB.

2010-02-17T04:23:00+00:00

Both the store queue API and the PMB remapping take unsigned long for
their pgprot flags, which cuts off the extended protection bits. In the
case of the PMB this isn't really a problem since the cache attribute
bits that we care about are all in the lower 32-bits, but we do it just
to be safe. The store queue remapping on the other hand depends on the
extended prot bits for enabling userspace access to the mappings.
