bnx2x: Calling netif_carrier_off at the end of the probe

netif_carrier_off was called too early at the probe. In case of failure
or simply bad timing, this can cause a fatal error since linkwatch_event
might run too soon.

bnx2x: PCI configuration bug on big-endian

The current code read nothing but zeros on big-endian (wrong part of the
32bits). This caused poor performance on big-endian machines. Though this
issue did not cause the system to crash, the performance is significantly
better with the fix so I view it as critical bug fix.

bnx2x: Removing the PMF indication when unloading

When the PMF flag is set, the driver can access the HW freely. When the
driver is unloaded, it should not access the HW. The problem caused fatal
errors when "ethtool -i" was called after the calling instance was unloaded
and another instance was already loaded

ext4: wait on all pending commits in ext4_sync_fs()

In ext4_sync_fs, we only wait for a commit to finish if we started it,
but there may be one already in progress which will not be synced.

In the case of a data=ordered umount with pending long symlinks which
are delayed due to a long list of other I/O on the backing block
device, this causes the buffer associated with the long symlinks to
not be moved to the inode dirty list in the second phase of
fsync_super. Then, before they can be dirtied again, kjournald exits,
seeing the UMOUNT flag and the dirty pages are never written to the
backing block device, causing long symlink corruption and exposing new
or previously freed block data to userspace.

To ensure all commits are synced, we flush all journal commits now
when sync_fs'ing ext4.

PCI: fix range check on mmapped sysfs resource files

pci_mmap_fits() returns the wrong answer if the sysfs resource file size
is not a multiple of the page size. vm_end and vm_start are already
page-aligned, so size - start < nr, causing mmap() to return EINVAL.

PCI: fix VPD limit quirk for Broadcom 5708S

VPD quirks need to be called after the VPD capability is initialized.
Since VPD initialization now runs after pci_fixup_header (due to the
capabilities consolidation), VPD quirks should be done at
pci_fixup_final stage correspondingly.

mv643xx_eth: fix SMI bus access timeouts

The mv643xx_eth mii bus implementation uses wait_event_timeout() to
wait for SMI completion interrupts.

If wait_event_timeout() would return zero, mv643xx_eth would conclude
that the SMI access timed out, but this is not necessarily true --
wait_event_timeout() can also return zero in the case where the SMI
completion interrupt did happen in time but where it took longer than
the requested timeout for the process performing the SMI access to be
scheduled again. This would lead to occasional SMI access timeouts
when the system would be under heavy load.

The fix is to ignore the return value of wait_event_timeout(), and
to re-check the SMI done bit after wait_event_timeout() returns to
determine whether or not the SMI access timed out.

tracing, ring-buffer: add paranoid checks for loops

While writing a new tracer, I had a bug where I caused the ring-buffer
to recurse in a bad way. The bug was with the tracer I was writing
and not the ring-buffer itself. But it took a long time to find the
problem.

This patch adds paranoid checks into the ring-buffer infrastructure
that will catch bugs of this nature.

Note: I put the bug back in the tracer and this patch showed the error
nicely and prevented the lockup.

ftrace: use kretprobe trampoline name to test in output

Impact: ia64+tracing build fix

When a function is kprobed, the return address is set to the
kprobe_trampoline, or something similar. This caused the output
of the trace to look confusing when the parent seemed to be this
"kprobe_trampoline" function.

To fix this, Abhishek Sagar added a test of the instruction pointer
of the parent to see if it matched the kprobe_trampoline. If it
did, the output would print a "[unknown/kretprobe'd]" instead.

Unfortunately, not all archs do this the same way, and the trampoline
function may not be exported, which causes failures in builds.

This patch will compare the name instead of the pointer to see
if it matches. This prevents us from depending on a function from
being exported, and should work on all archs. The worst that can
happen is that an arch might use a different name and then we
go back to the confusing output. At least the arch will still build.

XFRM: copy_to_user_kmaddress() reports local address twice

While adding support for MIGRATE/KMADDRESS in strongSwan (as specified
in draft-ebalard-mext-pfkey-enhanced-migrate-00), Andreas Steffen
noticed that XFRMA_KMADDRESS attribute passed to userland contains the
local address twice (remote provides local address instead of remote
one).

This bug in copy_to_user_kmaddress() affects only key managers that use
native XFRM interface (key managers that use PF_KEY are not affected).

For the record, the bug was in the initial changeset I posted which
added support for KMADDRESS (13c1d18931ebb5cf407cb348ef2cd6284d68902d
'xfrm: MIGRATE enhancements (draft-ebalard-mext-pfkey-enhanced-migrate)').
