[Qemu-devel] [PATCH] linux-user: declare sys_futex to have 6 arguments

[Petar Jovanovic]

From: Petar Jovanovic <address@hidden>

sys_futex has 6 arguments, and all of these need to be copied. Fix incorrect
declaration in the mips_syscall_args array.

This change fixes the cases where the 5th and 6th arguments have non-zero
value and have importance. An example is a Linux implementation of
pthread_cond_wait() function.
