[PATCH] x86-64: Fix race in exit_idle

2006-11-14T15:57:46+00:00

When another interrupt happens in exit_idle the exit idle notifier could be called an incorrect number of times. Add a test_and_clear_bit_pda and use it handle the bit atomically against interrupts to avoid this. Pointed out by Stephane Eranian Signed-off-by: Andi Kleen

[PATCH] Fix idle notifiers

2006-09-26T08:52:40+00:00

Previously exit_idle would be called more often than enter_idle Now instead of using complicated tests just keep track of it using the per CPU variable as a flip flop. I moved the idle state into the PDA to make the access more efficient. Original bug report and an initial patch from Stephane Eranian, but redone by AK.

[PATCH] Define __bad_pda_field as noreturn

2006-09-26T08:52:40+00:00

This quietens so warnings about uninitialized use of the return value of the pda read operations. Signed-off-by: Andi Kleen

[PATCH] Reindent macros in pda.h

2006-09-26T08:52:40+00:00

Reindent the macros in x86-64 pda.h, making them much more readable. Follows Jeremy's i386 version of this. No functional changes Signed-off-by: Andi Kleen

[PATCH] Type checking for write_pda()

2006-09-26T08:52:39+00:00

I just added type checking for assignments the PDA in the i386 PDA code. Here's the x86-64 equivalent. (Obviously this doesn't contain the latest x86-64 PDA change.) Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Andi Kleen

[PATCH] Use %c instead of %P modifier in pda access

2006-09-26T08:52:39+00:00

Apparently that is the more official way to get numbers without $ in inline assembly Signed-off-by: Andi Kleen

[PATCH] Add the canary field to the PDA area and the task struct

2006-09-26T08:52:38+00:00

This patch adds the per thread cookie field to the task struct and the PDA. Also it makes sure that the PDA value gets the new cookie value at context switch, and that a new task gets a new cookie at task creation time.

[PATCH] Add comments to the PDA structure to annotate offsets

2006-09-26T08:52:38+00:00

Change the comments in the pda structure to make the first fields to have their offset documented and to have the comments aligned. The stack protector series needs a field at offset 40 (gcc ABI); annotate upto 40 for that reason. Signed-off-by: Arjan van de Ven Signed-off-by: Ingo Molnar Signed-off-by: Andi Kleen CC: Andi Kleen

[PATCH] Remove most of the special cases for the debug IST stack

2006-09-26T08:52:38+00:00

Remove most of the special cases for the debug IST stack. This is a follow on clean up patch, it requires the bug fix patch that adds orig_ist. Signed-off-by: Keith Owens Signed-off-by: Andi Kleen
