Revision 598af051a79d05b751fe793f1fe09fcf74763e02 authored by Roland McGrath on 10 April 2008, 22:38:45 UTC, committed by Linus Torvalds on 11 April 2008, 00:28:26 UTC
Use asmlinkage_protect in sys_io_getevents, because GCC for i386 with CONFIG_FRAME_POINTER=n can decide to clobber an argument word on the stack, i.e. the user struct pt_regs. Here the problem is not a tail call, but just the compiler's use of the stack when it inlines and optimizes the body of the called function. This seems to avoid it.
