x86: consolidate the cpu/ related code usage

2007-10-23T20:37:23Z

The x86_64 arch/x86/kernel/Makefile uses references into arch/x86/kernel/cpu/... to use code from there. Unifiy it with the nicely structured i386 way and reuse the existing subdirectory make rules. Also move the machine check related source into ...kernel/cpu/mcheck, where the other machine check related code is. No code change. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

x86: convert cpuinfo_x86 array to a per_cpu array

2007-10-19T18:35:04Z

cpu_data is currently an array defined using NR_CPUS. This means that we overallocate since we will rarely really use maximum configured cpus. When NR_CPU count is raised to 4096 the size of cpu_data becomes 3,145,728 bytes. These changes were adopted from the sparc64 (and ia64) code. An additional field was added to cpuinfo_x86 to be a non-ambiguous cpu index. This corresponds to the index into a cpumask_t as well as the per_cpu index. It's used in various places like show_cpuinfo(). cpu_data is defined to be the boot_cpu_data structure for the NON-SMP case.

cpu hotplug: mce: fix cpu hotplug error handling

2007-10-18T21:37:21Z

- Clear kobject in percpu device_mce before calling sysdev_register() with Because mce_create_device() may fail and it leaves kobject filled with junk. It will be the problem when mce_create_device() will be called next time. - Fix error handling in mce_create_device() Error handling should not do sysdev_remove_file() with not yet added attributes. - Don't register hotcpu notifier when mce_create_device() returns error - Do mce_create_device() in CPU_UP_PREPARE instead of CPU_ONLINE Cc: Andi Kleen Signed-off-by: Akinobu Mita Cc: Gautham R Shenoy Cc: Oleg Nesterov Cc: Andi Kleen Cc: Jan Beulich Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Remove workaround for unimmunized rcu_dereference from mce_log()

Remove the rmb() from mce_log(), since the immunized version of rcu_dereference() makes it unnecessary. Signed-off-by: Paul E. McKenney Cc: Ingo Molnar Cc: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
