From: Kyle McMartin <[email protected]> The bug was that we were comparing __NR_syscalls to be greater or equal to the syscall number stored in %r20. __NR_syscalls is one greater than the last syscall though, so we're loading one entry beyond the end of the syscall table, and trying to jump to it. Fix this by only checking that we're greater, alternatively, we could have compared to (__NR_Linux_syscalls - 1) Signed-off-by: Kyle McMartin <[email protected]> --- arch/parisc/kernel/syscall.S | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/arch/parisc/kernel/syscall.S b/arch/parisc/kernel/syscall.S index 91b2a48..56f6231 100644 --- a/arch/parisc/kernel/syscall.S +++ b/arch/parisc/kernel/syscall.S @@ -198,7 +198,7 @@ linux_gateway_entry: ldil L%sys_call_table, %r1 ldo R%sys_call_table(%r1), %r19 #endif - comiclr,>>= __NR_Linux_syscalls, %r20, %r0 + comiclr,>> __NR_Linux_syscalls, %r20, %r0 b,n .Lsyscall_nosys LDREGX %r20(%r19), %r19 -- 1.5.1.3
