parisc: Don't use BITS_PER_LONG in userspace-exported swab.h header

In swab.h the "#if BITS_PER_LONG > 32" breaks compiling userspace programs if BITS_PER_LONG is #defined by userspace with the sizeof() compiler builtin. Solve this problem by using __BITS_PER_LONG instead. Since we now #include asm/bitsperlong.h avoid further potential userspace pollution by moving the #define of SHIFT_PER_LONG to bitops.h which is not exported to userspace. This patch unbreaks compiling qemu on hppa/parisc. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org>

Pull namespace fixes from Eric Biederman: "This tree contains 4 fixes. The first is a fix for a race that can causes oopses under the right circumstances, and that someone just recently encountered. Past that are several small trivial correct fixes. A real issue that was blocking development of an out of tree driver, but does not appear to have caused any actual problems for in-tree code. A potential deadlock that was reported by lockdep. And a deadlock people have experienced and took the time to track down caused by a cleanup that removed the code to drop a reference count" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: sysctl: Drop reference added by grab_header in proc_sys_readdir pid: fix lockdep deadlock warning due to ucount_lock libfs: Modify mount_pseudo_xattr to be clear it is not a userspace mount mnt: Protect the mountpoint hashtable with mount_lock
