Gcc might emit an absolute address for the the "m" constraint which gas unfortunately does not permit. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2006-04-19[MIPS] Rewrite all the assembler interrupt handlers to C.Ralf Baechle
Saves like 1,600 lines of code, is way easier to debug, compilers frequently do a better job than the cut and paste type of handlers many boards had. And finally having all the stuff done in a single place also means alot of bug potencial for the MT ASE is gone. The only surviving handler in assembler is the DECstation one; I hope Maciej will rewrite it. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-04-18x86: be careful about tailcall breakage for sys_open[at] tooLinus Torvalds
Came up through a quick grep for other cases similar to the ftruncate() one in commit 0a489cb3b6a7b277030cdbc97c2c65905db94536. Also, add a comment, so that people who read the code understand why we do what looks like a no-op. (Again, this won't actually matter to any sane user, since libc will save and restore the register gcc stomps on, but it's still wrong to stomp on it) Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-04-18x86: don't allow tail-calls in sys_ftruncate[64]()Linus Torvalds
Gcc thinks it owns the incoming argument stack, but that's not true for "asmlinkage" functions, and it corrupts the caller-set-up argument stack when it pushes the third argument onto the stack. Which can result in %ebx getting corrupted in user space. Now, normally nobody sane would ever notice, since libc will save and restore %ebx anyway over the system call, but it's still wrong. I'd much rather have "asmlinkage" tell gcc directly that it doesn't own the stack, but no such attribute exists, so we're stuck with our hacky manual "prevent_tail_call()" macro once more (we've had the same issue before with sys_waitpid() and sys_wait4()). Thanks to Hans-Werner Hilse <hilse@sub.uni-goettingen.de> for reporting the issue and testing the fix. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

o Start booting into the capture kernel after an Oops if system is in a unrecoverable state. System will boot into the capture kernel, if one is pre-loaded by the user, and capture the kernel core dump. o One of the following conditions should be true to trigger the booting of capture kernel. - panic_on_oops is set. - pid of current thread is 0 - pid of current thread is 1 - Oops happened inside interrupt context.

2006-04-18[PATCH] cfq: Further rbtree traversal and cfq_exit_queue() race fixOGAWA Hirofumi
In current code, we are re-reading cic->key after dead cic->key check. So, in theory, it may really re-read *after* cfq_exit_queue() seted NULL. To avoid race, we copy it to stack, then use it. With this change, I guess gcc will assign cic->key to a register or stack, and it wouldn't be re-readed.
