X-Git-Tag: v4.7-rc2~15^2~8
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=10fdf8513f776c8b2588bb7b924fb243ae2462d6;p=linux.git

arm64: unistd32.h: wire up missing syscalls for compat tasks

We're missing entries for mlock2, copy_file_range, preadv2 and pwritev2
in our compat syscall table, so hook them up. Only the last two need
compat wrappers.
