here is a fix to a previous ChangeSet from John; 32-bit emulation of flock(fd,
F_GETLK, &lock) currently is broken.

The ChangeSet:
http://linux.bkbits.net:8080/linux-2.5/cset%404152257aJKu1UClRcfvhsK6IjGYSeQ?nav=index.html|ChangeSet@-12w
from John Engel <jhe@us.ibm.com> fixes an off-by-one error and according
to the ChangeSet comment, it also contains a fix to handle l_len < 0 which
is now defined in POSIX 1003.1-2001 from the fcntl man page.

Gordon Jin <gordon.jin@intel.com> reports that the added test causes
compat_sys_fcntl[64] to fail: If fcntl(fd, F_GETLK, &lock) finds no
conflicting lock it sets l_whence to F_UNLCK, leaves all the other fields
unchanged, and returns 0.  The (f.l_start < 0) test wrongly converts this
to an EINVAL result.

The underlying sys_fcntl function which compat_sys_fcntl and
compat_sys_fcntl64 invoke already handles POSIX behavior correctly.  The
additional tests in the compat wrappers are not needed.

Here is a test case; its expected result is:

PASS

 * s_4bri.c has a nasty typo - bogus & in qBri_cpu_trapped().

   We have
	void *base;
   followed by
	regs[0] = READ_DWORD((&base + offset) + 0x70);

   which is *NOT* what is meant there - instead of access to memory
   pointed to by base we get access to _stack_ at some offset from the
   place where the local variable base lives.

Patch from Christoph Hellwig

These routine in arm is unused (in fact not even compiled).

Instead of converting it to local_softirq_pending I'd suggest just
removing it as below as it's been there totally unused for a long
time.

The special non-signalling NaN flag was escaping and setting some
FPSCR exception enable flags.  Ensure that this flag is masked out
before we update the FPSCR.
