x86_64: Prevent doing anything from cache_remove_dev() when info setup failed.

2007-09-12T16:28:06+00:00

AK: Removed the unlikelies because gcc heuristics default to unlikely AK: for test == NULL and for negative returns. Cc: Venkatesh Pallipadi Cc: Ashok Raj Cc: Akinobu Mita Signed-off-by: Jan Beulich Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

i386: fix section mismatch warning in intel_cacheinfo

2007-07-22T01:37:12+00:00

Fix following warning: WARNING: arch/i386/kernel/built-in.o(.init.text+0x3818): Section mismatch: reference to .exit.text:cache_remove_dev (between 'cacheinfo_cpu_callback' and 'cache_sysfs_init') It points out that a function marked __cpuexit is calling a function marked __cpuinit => oops. The call happens only in an error-condition which may explain why we have not seen it before. The offending function was not used anywhere else - so marked it __cpuexit. Note: This warning triggers only with a local copy of modpost but that version will soon be pushed out.

i386: Add L3 cache support to AMD CPUID4 emulation

2007-07-22T01:37:08+00:00

With that an L3 cache is correctly reported in the cache information in /sys With fixes from Andreas Herrmann and Dean Gaudet and Joachim Deguara Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

i386: intel_cacheinfo.c:find_num_cache_leaves() should be __cpuinit

2007-07-22T00:49:15+00:00

WARNING: arch/i386/kernel/built-in.o(.text+0xb6a7): Section mismatch: reference to .init.text:find_num_cache_leaves (between 'init_intel_cacheinfo' and 'cache_shared_cpu_map_setup') It could be __init_refok, but gcc >= 4.0 anyway inlines it into the __cpuinit init_intel_cacheinfo(), and IMHO it's too small for "noinline __init".

Add suspend-related notifications for CPU hotplug

2007-05-09T19:30:56+00:00

Since nonboot CPUs are now disabled after tasks and devices have been frozen and the CPU hotplug infrastructure is used for this purpose, we need special CPU hotplug notifications that will help the CPU-hotplug-aware subsystems distinguish normal CPU hotplug events from CPU hotplug events related to a system-wide suspend or resume operation in progress. This patch introduces such notifications and causes them to be used during suspend and resume transitions. It also changes all of the CPU-hotplug-aware subsystems to take these notifications into consideration (for now they are handled in the same way as the corresponding "normal" ones).

[PATCH] cpu hotplug: use hotplug version of registration in late inits

[PATCH] cpu hotplug: make cpu_notifier related notifier blocks __cpuinit only

2006-06-28T00:32:41+00:00

Make notifier_blocks associated with cpu_notifier as __cpuinitdata. __cpuinitdata makes sure that the data is init time only unless CONFIG_HOTPLUG_CPU is defined. Signed-off-by: Chandra Seetharaman Cc: Ashok Raj Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] cpu hotplug: revert init patch submitted for 2.6.17

2006-06-28T00:32:40+00:00

In 2.6.17, there was a problem with cpu_notifiers and XFS. I provided a band-aid solution to solve that problem. In the process, i undid all the changes you both were making to ensure that these notifiers were available only at init time (unless CONFIG_HOTPLUG_CPU is defined). We deferred the real fix to 2.6.18. Here is a set of patches that fixes the XFS problem cleanly and makes the cpu notifiers available only at init time (unless CONFIG_HOTPLUG_CPU is defined). If CONFIG_HOTPLUG_CPU is defined then cpu notifiers are available at run time. This patch reverts the notifier_call changes made in 2.6.17 Signed-off-by: Chandra Seetharaman Cc: Ashok Raj Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
