powerpc: Rename slb0_limit() to safe_stack_limit() and add Book3E support

2011-05-06T03:32:24+00:00

slb0_limit() wasn't a very descriptive name. This changes it along with
a comment explaining what it's used for, and provides a 64-bit BookE
implementation.

powerpc: Free up some CPU feature bits by moving out MMU-related features

2011-04-27T04:18:52+00:00

Some of the 64bit PPC CPU features are MMU-related, so this patch moves
them to MMU_FTR_ bits.  All cpu_has_feature()-style tests are moved to
mmu_has_feature(), and seven feature bits are freed as a result.

powerpc: Properly handshake CPUs going out of boot spin loop

2011-04-20T01:03:24+00:00

We need to wait a bit for them to have done their CPU setup
or we might end up with translation and EE on with different
LPCR values between threads

powerpc: Fix incorrect comment about interrupt stack allocation

2010-12-09T04:35:31+00:00

We now allow interrupt stacks anywhere in the first segment which can be
256M or 1TB. Fix the comment.

powerpc: Update a BKL related comment

2010-11-18T03:54:24+00:00

The commit 5e3d20a remove bkl from startup code so setup_arch() it isn't called
with bkl held anymore. Update the comment on top of that function.
Fix also a typo.

powerpc: Correct smt_enabled=X boot option for > 2 threads per core

2010-08-24T05:26:30+00:00

The 'smt_enabled=X' boot option does not handle values of X > 2.
For Power 7 processors with smt modes of 0,1,2,3, and 4 this does
not work.  This patch allows the smt_enabled option to be set to
any value limited to a max equal to the number of threads per
core.

memblock: Remove rmo_size, burry it in arch/powerpc where it belongs

2010-08-05T02:56:08+00:00

The RMA (RMO is a misnomer) is a concept specific to ppc64 (in fact
server ppc64 though I hijack it on embedded ppc64 for similar purposes)
and represents the area of memory that can be accessed in real mode
(aka with MMU off), or on embedded, from the exception vectors (which
is bolted in the TLB) which pretty much boils down to the same thing.

We take that out of the generic MEMBLOCK data structure and move it into
arch/powerpc where it belongs, renaming it to "RMA" while at it.
