1723b4a34a [MIPS] Make timer interrupt frequency configurable from kconfig.
Make HZ configurable.  DECSTATION can select 128/256/1024 HZ, JAZZ can
only select 100 HZ, others can select 100/128/250/256/1000/1024 HZ if
not explicitly specified).  Also remove all mach-xxx/param.h files and
update all defconfigs according to current HZ value.

2925aba422 [MIPS] Cleanup memory managment initialization.
Historically plat_mem_setup did the entire platform initialization.  This
was rather impractical because it meant plat_mem_setup had to get away
without any kind of memory allocator.  To keep old code from breaking
plat_setup was just renamed to plat_setup and a second platform
initialization hook for anything else was introduced.

e4ac58afdf [MIPS] Rewrite all the assembler interrupt handlers to C.
Saves like 1,600 lines of code, is way easier to debug, compilers
frequently do a better job than the cut and paste type of handlers many
boards had.  And finally having all the stuff done in a single place
also means alot of bug potencial for the MT ASE is gone.

The only surviving handler in assembler is the DECstation one; I hope
Maciej will rewrite it.

7835e98b2e [PATCH] remove set_page_count() outside mm/
set_page_count usage outside mm/ is limited to setting the refcount to 1.
Remove set_page_count from outside mm/, and replace those users with
init_page_count() and set_page_refcounted().

This allows more debug checking, and tighter control on how code is allowed
to play around with page->_count.

53c2df2f4e Use rtc_lock to protect RTC operations
Many RTC routines were not protected against each other, so there are
potential races, for example, ntp-update against /dev/rtc.  This patch
fixes them using rtc_lock.

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!
