stmmac: fix phy naming inconsistency

After commit "db8857b stmmac: use an unique MDIO bus name" my
device stopped being probed because two different names were being
used in different places. This fixes the inconsistency.

llc: Fix race condition in llc_ui_recvmsg

There is a race on sk_receive_queue between llc_ui_recvmsg and
sock_queue_rcv_skb.

Our current solution is to protect skb_eat in llc_ui_recvmsg
with the queue spinlock.

jsm: Fixed EEH recovery error

There was an error on the jsm driver that would cause it to be unable to
recover after a second error is detected.

At the first error, the device recovers properly:

[72521.485691] EEH: Detected PCI bus error on device 0003:02:00.0
[72521.485695] EEH: This PCI device has failed 1 times in the last hour:
...
[72532.035693] ttyn3 at MMIO 0x0 (irq = 49) is a jsm
[72532.105689] jsm: Port 3 added

However, at the second error, it cascades until EEH disables the device:

[72631.229549] Call Trace:
...
[72641.725687] jsm: Port 3 added
[72641.725695] EEH: Detected PCI bus error on device 0003:02:00.0
[72641.725698] EEH: This PCI device has failed 3 times in the last hour:

It was caused because the PCI state was not being saved after the first
restore. Therefore, at the second recovery the PCI state would not be
restored.

TTY: fix UV serial console regression

Commit 74c2107759d (serial: Use block_til_ready helper) and its fixup
3f582b8c110 (serial: fix termios settings in open) introduced a
regression on UV systems. The serial eventually freezes while being
used. It's completely unpredictable and sometimes needs a heap of
traffic to happen first.

To reproduce this, yast installation was used as it turned out to be
pretty reliable in reproducing. Especially during installation process
where one doesn't have an SSH daemon running. And no monitor as the HW
is completely headless. So this was fun to find. Given the machine
doesn't boot on vanilla before 2.6.36 final. (And the commits above
are older.)

Unless there is some bad race in the code, the hardware seems to be
pretty broken. Otherwise pure MSR read should not cause such a bug,
or?

So to prevent the bug, revert to the old behavior. I.e. read modem
status only if we really have to -- for non-CLOCAL set serials.
Non-CLOCAL works on this hardware OK, I tried. See? I don't.

And document that shit.

PCMCIA: fix sa1111 oops on remove

Unable to handle kernel NULL pointer dereference at virtual address 000003b0

rds: Make rds_sock_lock BH rather than IRQ safe.

rds_sock_info() triggers locking warnings because we try to perform a
local_bh_enable() (via sock_i_ino()) while hardware interrupts are
disabled (via taking rds_sock_lock).

There is no reason for rds_sock_lock to be a hardware IRQ disabling
lock, none of these access paths run in hardware interrupt context.

Therefore making it a BH disabling lock is safe and sufficient to
fix this bug.
