[PATCH 1/1] powerpc: Individual System V IPC system calls

[PATCH 1/1] powerpc: Individual System V IPC system calls

[Sam Bobroff]

This patch provides individual system call numbers for the following
System V IPC system calls, on PowerPC, so that they do not need to be
multiplexed:
* semop, semget, semctl, semtimedop
* msgsnd, msgrcv, msgget, msgctl
* shmat, shmdt, shmget, shmctl

Thanks.

Can you please rebase this on top of linux-next, where we have two new
syscalls wired up. It should be trivial, just the numbering changes, but I
think you have a modified libc to actually test the result.

cheers

No problem, and yes I can test the glibc changes :-)

Cheers,
