46684734dd [MIPS] unexport null_perf_irq() and make it static
This patch unexports the null_perf_irq() symbol, and simultaneously
makes this function static.

39a51109dd [MIPS] Extend performance counter event field.
The latest draft version of the MIPS Architecture Specification extends the
6 bit event field by adding a directly adjacent 4-bit EventExt field for a
total of 10 bits.

5e2862eb5a [MIPS] Oprofile: Fix computation of number of counters.
VSMP kernels will split the available performance counters between the two
processors / cores.  But don't do this when we're not on a VSMP system ...

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."

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.

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!
