[PATCH] i386: fix prevent_tail_call
We fixed this bug before, but it didn't take. It may have been the case that the problem was first noticed to occur in a CONFIG_REGPARM compile. But it's not regparm functions that need not to make tail calls, it's asmlinkage functions called with a user pt_regs frame on the stack supplying their arguments. prevent_tail_call probably doesn't do anything at all in regparm functions (your argument registers are going to be clobbered, period). It was a braino to conditionalize that definition in the first place. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
