Hi Clifford,

Thanks for the report.

PowerPC problems should be reported to linuxppc-dev@ozlabs.org.

This has been fixed in the current (approaching 2.6.24) kernel.  It
should be fixed in 2.6.23.xx, so I have cc'd this to
stable@vger.kernel.org (and linuxppc-dev, of course).

(Also, please post patches inline, don't attach them.  And you need to
reply to this with a Signed-off-by: line.)

Hi,

In current 2.6.23 (I have checked 2.6.23.12 and 2.6.23.9) the end of
include/asm-powerpc/systbl.h reads:

--snip--
SYSCALL_SPU(getcpu)
COMPAT_SYS(epoll_pwait)
COMPAT_SYS_SPU(utimensat)
COMPAT_SYS(fallocate)
COMPAT_SYS_SPU(signalfd)
COMPAT_SYS_SPU(timerfd)
SYSCALL_SPU(eventfd)
COMPAT_SYS_SPU(sync_file_range2)
--snap--

This obviously does not match the definitions in asm-powerpc/unistd.h:

--snip--
#define __NR_getcpu		302
#define __NR_epoll_pwait	303
#define __NR_utimensat		304
#define __NR_signalfd		305
#define __NR_timerfd		306
#define __NR_eventfd		307
#define __NR_sync_file_range2	308
#define __NR_fallocate		309
--snap--

which breaks the system calls 305 to 309 inclusive.

Should have been stable@kernel.org. (where I have sent another copy of
the email)
