powerpc/vphn: Fix arch_update_cpu_topology() return value

2012-09-05T06:05:19+00:00

arch_update_cpu_topology() should only return 1 when the topology has actually changed, and should return 0 otherwise. This patch fixes a potential bug where rebuild_sched_domains() would reinitialize the sched domains even when the topology hasn't changed.

KVM: PPC: Add cache flush on page map

2012-08-16T12:14:53+00:00

When we map a page that wasn't icache cleared before, do so when first mapping it in KVM using the same information bits as the Linux mapping logic. That way we are 100% sure that any page we map does not have stale entries in the icache. Signed-off-by: Alexander Graf

powerpc: Enforce usage of RA 0-R31 where possible

2012-07-10T09:18:35+00:00

Some macros use RA where when RA=R0 the values is 0, so make this the enforced mnemonic in the macro. Idea suggested by Andreas Schwab. Signed-off-by: Michael Neuling Signed-off-by: Benjamin Herrenschmidt

powerpc: Fixes for instructions not using correct register naming

2012-07-10T09:18:16+00:00

These macros are using integers where they could be using logical names since they take registers. We are going to enforce this soon, so fix these up now. Signed-off-by: Michael Neuling Signed-off-by: Benjamin Herrenschmidt

powerpc: Merge STK_REG/PARAM/FRAMESIZE

2012-07-10T09:18:03+00:00

Merge the defines of STACKFRAMESIZE, STK_REG, STK_PARAM from different places. Signed-off-by: Michael Neuling Signed-off-by: Benjamin Herrenschmidt

powerpc: Fix usage of register macros getting ready for %r0 change

2012-07-10T09:17:55+00:00

Anything that uses a constructed instruction (ie. from ppc-opcode.h), need to use the new R0 macro, as %r0 is not going to work. Also convert usages of macros where we are just determining an offset (usually for a load/store), like: std r14,STK_REG(r14)(r1) Can't use STK_REG(r14) as %r14 doesn't work in the STK_REG macro since it's just calculating an offset.

We want to bring in the latest IRQ fixes

powerpc/numa: Avoid stupid uninitialized warning from gcc

2012-07-10T09:16:23+00:00

Newer gcc are being a bit blind here (it's pretty obvious we don't reach the code path using the array if we haven't initialized the pointer) but none of that is performance critical so let's just silence it. Signed-off-by: Benjamin Herrenschmidt

powerpc/numa: Fix OF node refcounting bug

2012-07-03T04:14:44+00:00

The form affinity for NUMA is set to 1 if the firmware supports OPAL. Otherwise, we have to retrieve that from OF node "/chosen". For the latter case, OF node "/chosen" reference count was never decreased. Signed-off-by: Gavin Shan Signed-off-by: Benjamin Herrenschmidt
