S390: fix futex_atomic_cmpxchg_inatomic

2006-08-07T03:52:16+00:00

[S390] fix futex_atomic_cmpxchg_inatomic

futex_atomic_cmpxchg_inatomic has the same bug as the other
atomic futex operations: the operation needs to be done in the
user address space, not the kernel address space. Add the missing
sacf 256 & sacf 0.

[PATCH] s390: fix in-user atomic futex operation.

2006-06-08T22:15:30+00:00

From: Martin Schwidefsky 

__futex_atomic_op needs to do an atomic operation in the user address space,
not the kernel address space.  Add the missing sacf 256/sacf 0 to switch to
the secondary mode before doing the compare-and-swap.  In addition add
another fixup for catch specification exceptions if the compare-and-swap
address is not aligned.

[PATCH] s390: cio non-unique path group ids

2006-06-05T19:29:16+00:00

From: Peter Oberparleiter 

The path grouping can fail due to non-unique pathgroup-IDs.  The source for
the CPU-ID part of the ID was incorrectly specified on 64 bit systems.
Additionally, the length of the ID was too large due to incorrect data packing
declaration.  Fix CPU-ID lowcore address and add missing packing declaration.

[PATCH] s390: add read_mostly optimization

2006-04-28T15:33:48+00:00

Add a read_mostly section and define __read_mostly to prevent cache line
pollution due to writes for mostly read variables.  In addition fix the
incorrect alignment of the cache_line_aligned data section.  s390 has a
cacheline size of 256 bytes.

[PATCH] for_each_possible_cpu: s390

2006-03-31T20:18:52+00:00

for_each_cpu() actually iterates across all possible CPUs.  We've had mistakes
in the past where people were using for_each_cpu() where they should have been
iterating across only online or present CPUs.  This is inefficient and
possibly buggy.

We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the
future.

This patch replaces for_each_cpu with for_each_possible_cpu.
