Kuninori Morimoto 0207a2efb4 sh: Add support for SH7724 (SH-Mobile R2R) CPU subtype.
This implements initial support for the SH-Mobile R2R CPU.
Based on Rev 0.11 of the initial SH7724 hardware manual.

Kuninori Morimoto 55ba99eb21 sh: Add support for SH7786 CPU subtype.
This adds preliminary support for the SH7786 CPU subtype.

While this is a dual-core CPU, only UP is supported for now. L2 cache
support is likewise not yet implemented.

More information on this particular CPU subtype is available at:

Paul Mundt 60a51fbe5d sh: oprofile: Refactor common setup code for multiple driver support.
This re-implements the old op_model_null code in to something more
generic, where multiple drivers, backtrace, etc. can all be interfaced.
Based largely on arch/mips/oprofile/common.c.

Paul Mundt 2a88b6e815 sh: oprofile: Fix up the SH7750 performance counter name.
Rather than varying this on a subtype level, we use the counter type as a
generic identifier. This simplifies logic in the userspace tools where no
fundamental difference exists across the various subtypes.

Paul Mundt b46378bc59 sh: Make SH7750 oprofile compile again.
Converts from the profile notifier to the timer hook. Follows
the generic timer interrupt-based change.

This really wants to be converted to perfmon..

Mathieu Desnoyers 09cadedbdc Combine instrumentation menus in kernel/Kconfig.instrumentation
Quoting Randy:

"It seems sad that this patch sources Kconfig.marker, a 7-line file,
20-something times.  Yes, you (we) don't want to put those 7 lines into
20-something different files, so sourcing is the right thing.

However, what you did for avr32 seems more on the right track to me: make
_one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES,
and MARKERS and then use (source) that in all of the arches."

Arjan van de Ven 5dfe4c964a [PATCH] mark struct file_operations const 2
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

Markus Armbruster 0c6856f702 [PATCH] oprofile: Fix unnecessary cleverness
nmi_create_files() in arch/i386/oprofile/nmi_int.c depends on
model->num_counters (number of performance counters) being less than 10.
While this is currently the case, it's too clever by half.

Other archs aren't quite as clever: they assume 100.  I suggest to
normalize them all to 1000.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
