    x86/syscalls: Add compat_sys_preadv64v2/compat_sys_pwritev64v2 · 3ebfd81f
    H.J. Lu authored
    Don't use the same syscall numbers for 2 different syscalls:
    
     534	x32	preadv			compat_sys_preadv64
     535	x32	pwritev			compat_sys_pwritev64
     534	x32	preadv2			compat_sys_preadv2
     535	x32	pwritev2		compat_sys_pwritev2
    
    Add compat_sys_preadv64v2() and compat_sys_pwritev64v2() so that 64-bit offset
    is passed in one 64-bit register on x32, similar to compat_sys_preadv64()
    and compat_sys_pwritev64().
