Taking namespace_sem shared there isn't worth the trouble, especially with
vfsmount ID allocation about to be added.  That way we know that umount_tree(),
copy_tree() and clone_mnt() are _always_ serialized by namespace_sem.
umount_tree() still needs vfsmount_lock (it manipulates hash chains, among
other things), but that's a separate story.

Signed-off-by: NRoland Dreier <rolandd@cisco.com>

The PCI MSI interface is stubbed out properly so that all the
functions just return failure if PCI_MSI=n, so there's no reason to
have "#ifdef CONFIG_PCI_MSI" blocks in ipath_iba7220.c.
Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Before IBA7220 support was added, the ipath driver didn't support any
hardware unless PCI_MSI and/or HT_IRQ was enabled.  However, the
IBA7220 can generate INTx interrupts, so it makes sense to allow the
driver to be build even if PCI_MSI=n and HT_IRQ=n.
Signed-off-by: NRoland Dreier <rolandd@cisco.com>

The new IBA7220 code added a call to ipath_init_iba7220_funcs() that
is compiled unconditionally, but only built the IBA7220 code if
PCI_MSI is enabled.  Fix this by building the IBA7220 file
unconditonally.

This fixes build breakage when PCI_MSI=n, HT_IRQ=y and
INFINIBAND_IPATH=y reported by Ingo Molnar <mingo@elte.hu>:

This adds support for PTRACE_GETSIGINFO and PTRACE_SETSIGINFO in
compat_ptrace_request.  It relies on existing arch definitions for
copy_siginfo_to_user32 and copy_siginfo_from_user32.

On powerpc, this fixes a longstanding regression of 32-bit ptrace
calls on 64-bit kernels vs native calls (64-bit calls or 32-bit
kernels).  This can be seen in a 32-bit call using PTRACE_GETSIGINFO
to examine e.g. siginfo_t.si_addr from a signal that sets it.
