powerpc: Copy down exception vectors after feature fixups

2011-11-21T22:31:25Z

commit d715e433b7ad19c02fc4becf0d5e9a59f97925de upstream. kdump fails because we try to execute an HV only instruction. Feature fixups are being applied after we copy the exception vectors down to 0 so they miss out on any updates. We have always had this issue but it only became critical in v3.0 when we added CFAR support (breaks POWER5) and v3.1 when we added POWERNV (breaks everyone).

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

2011-05-06T03:32:24Z

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. Signed-off-by: Benjamin Herrenschmidt

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

2011-04-27T04:18:52Z

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. Signed-off-by: Matt Evans Signed-off-by: Benjamin Herrenschmidt

powerpc: Properly handshake CPUs going out of boot spin loop

2011-04-20T01:03:24Z

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 Signed-off-by: Benjamin Herrenschmidt

powerpc: Fix incorrect comment about interrupt stack allocation

2010-12-09T04:35:31Z

We now allow interrupt stacks anywhere in the first segment which can be 256M or 1TB. Fix the comment. Signed-off-by: Anton Blanchard Signed-off-by: Benjamin Herrenschmidt

powerpc: Update a BKL related comment

2010-11-18T03:54:24Z

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. This work was supported by a hardware donation from the CE Linux Forum. Signed-off-by: Alessio Igor Bogani Signed-off-by: Benjamin Herrenschmidt

Merge commit 'v2.6.36-rc3' into x86/memblock

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

2010-08-24T05:26:30Z

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. Signed-off-by: Nathan Fontenot Signed-off-by: Benjamin Herrenschmidt

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

2010-08-05T02:56:08Z

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. Signed-off-by: Benjamin Herrenschmidt
