David S. Miller 0f78e7542e [SPARC64]: Remove DEBUG_BOOTMEM.
We'll replace it in the future with better logging facilities that can
be enabled at run time.

Rafael J. Wysocki b0cb1a19d0 Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATION
Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATION to avoid
confusion (among other things, with CONFIG_SUSPEND introduced in the
next patch).

Andrew Morton 4a2f0acf0f [PATCH] kconfig: clarify memory debug options
The Kconfig text for CONFIG_DEBUG_SLAB and CONFIG_DEBUG_PAGEALLOC have always
seemed a bit confusing.  Change them to:

CONFIG_DEBUG_SLAB: "Debug slab memory allocations"
CONFIG_DEBUG_PAGEALLOC: "Debug page memory allocations"

Prasanna S Panchamukhi cd6b0762a0 [PATCH] Move Kprobes and Oprofile to "Instrumentation Support" menu
Andrew Morton suggested to move kprobes from kernel hacking menu, since
kernel hacking menu is in-appropriate for the Kprobes.  This patch moves
Kprobes and Oprofile under instrumentation menu.

(akpm: it's not a natural fit, but things like djprobes and the s390 guys'
statistics library need a home)

David S. Miller 5642530651 [SPARC64]: Add CONFIG_DEBUG_PAGEALLOC support.
The trick is that we do the kernel linear mapping TLB miss starting
with an instruction sequence like this:

	ba,pt		%xcc, kvmap_load
	 xor		%g2, %g4, %g5

succeeded by an instruction sequence which performs a full page table
walk starting at swapper_pg_dir.

We first take over the trap table from the firmware.  Then, using this
constant PTE generation for the linear mapping area above, we build
the kernel page tables for the linear mapping.

After this is setup, we patch that branch above into a "nop", which
will cause TLB misses to fall through to the full page table walk.

With this, the page unmapping for CONFIG_DEBUG_PAGEALLOC is trivial.

David S. Miller 4db2ce0199 [LIB]: Consolidate _atomic_dec_and_lock()
Several implementations were essentialy a common piece of C code using
the cmpxchg() macro.  Put the implementation in one spot that everyone
can share, and convert sparc64 over to using this.

Alpha is the lone arch-specific implementation, which codes up a
special fast path for the common case in order to avoid GP reloading
which a pure C version would require.

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!
