x86: unify chunks of kernel/process*.c

2009-03-02T11:07:48Z

With x86-32 and -64 using the same mechanism for managing the tss io permissions bitmap, large chunks of process*.c are trivially unifyable, including: - exit_thread - flush_thread - __switch_to_xtra (along with tsc enable/disable) and as bonus pickups: - sys_fork - sys_vfork (Note: asmlinkage expands to empty on x86-64) Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar

x86: fix x86_32 stack protector bugs

2009-02-11T10:33:49Z

Impact: fix x86_32 stack protector Brian Gerst found out that %gs was being initialized to stack_canary instead of stack_canary - 20, which basically gave the same canary value for all threads. Fixing this also exposed the following bugs. * cpu_idle() didn't call boot_init_stack_canary() * stack canary switching in switch_to() was being done too late making the initial run of a new thread use the old stack canary value. Fix all of them and while at it update comment in cpu_idle() about calling boot_init_stack_canary(). Reported-by: Brian Gerst Signed-off-by: Tejun Heo Signed-off-by: Ingo Molnar

x86, 64-bit: print DMI info in the oops trace

2009-02-04T21:10:12Z

This patch echoes what we already do on 32-bit since 90f7d25c6b672137344f447a30a9159945ffea72, and prints the DMI product name in show_regs, so that system specific problems can be easily identified. Signed-off-by: Kyle McMartin Signed-off-by: Ingo Molnar

x86: cleanup stack protector

2009-01-20T03:29:19Z

Impact: cleanup Make the following cleanups. * remove duplicate comment from boot_init_stack_canary() which fits better in the other place - cpu_idle(). * move stack_canary offset check from __switch_to() to boot_init_stack_canary(). Signed-off-by: Tejun Heo
