Impact: add oops-recursion check to 32-bit Unify the oops state-machine, to the 64-bit version. It is slightly more careful in that it does a recursion check in oops_begin(), and is thus more likely to show the relevant oops. It also means that 32-bit will print one more line at the end of pagefault triggered oopses: printk(KERN_EMERG "CR2: %016lx\n", address); Which is generally good information to be seen in partial-dump digital-camera jpegs ;-) The downside is the somewhat more complex critical path. Both variants have been tested well meanwhile by kernel developers crashing their boxes so i dont think this is a practical worry. This removes 3 ugly #ifdefs from no_context() and makes the function a lot nicer read. Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> |
