Kyle McMartin c20a84c910 [PARISC] futex: special case cmpxchg NULL in kernel space ... Commit a0c1e9073e added code to futex.c to detect whether futex_atomic_cmpxchg_inatomic was implemented at run time: + curval = cmpxchg_futex_value_locked(NULL, 0, 0); + if (curval == -EFAULT) + futex_cmpxchg_enabled = 1; This is bogus on parisc, since page zero in kernel virtual space is the gateway page for syscall entry, and should not be read from the kernel. (That, and we really don't like the kernel faulting on its own address space...) Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>		2008-03-15 19:12:17 -07:00
