d1d73578e0 backlight: grab ops_lock before testing bd->ops
According to the comment describing ops_lock in the definition of struct
backlight_device and when comparing with other functions in backlight.c
the mutex must be hold when checking ops to be non-NULL.

Fixes a problem added by c835ee7f41 ("backlight: Add suspend/resume
support to the backlight core") in Jan 2009.

c22c7aeff6 sgi-xpc: XPC fails to discover partitions with all nasids above 128
UV hardware defines 256 memory protection regions versus the baseline 64
with increasing size for the SN2 ia64.  This was overlooked when XPC was
modified to accomodate both UV and SN2.

Without this patch, a user could reconfigure their existing system and
suddenly disable cross-partition communications with no indication of what
has gone wrong.  It also prevents larger configurations from using
cross-partition communication.

be20e6c67b md: Call blk_queue_flush() to establish flush/fua support
Before 2.6.37, the md layer had a mechanism for catching I/Os with the
barrier flag set, and translating the barrier into barriers for all
the underlying devices.  With 2.6.37, I/O barriers have become plain
old flushes, and the md code was updated to reflect this.  However,
one piece was left out -- the md layer does not tell the block layer
that it supports flushes or FUA access at all, which results in md
silently dropping flush requests.

Since the support already seems there, just add this one piece of
bookkeeping.

8f9e0ee38f md/raid1: really fix recovery looping when single good device fails.
Commit 4044ba58dd supposedly fixed a
problem where if a raid1 with just one good device gets a read-error
during recovery, the recovery would abort and immediately restart in
an infinite loop.

However it depended on raid1_remove_disk removing the spare device
from the array.  But that does not happen in this case.  So add a test
so that in the 'recovery_disabled' case, the device will be removed.

This suitable for any kernel since 2.6.29 which is when
recovery_disabled was introduced.

rdev_size_store() expects the return value of rdev_size_change() to be

This functionality was broken by commit

1233471572 xen/events: Use PIRQ instead of GSI value when unmapping MSI/MSI-X irqs.
When we allocate a vector for MSI/MSI-X we save away the PIRQ, and the
vector value. When we unmap (de-allocate) the MSI/MSI-X vector(s) we
need to provide the PIRQ and the vector value. What we did instead
was to provide the GSI (which was zero) and the vector value, and we
got these unhappy error messages:

(XEN) irq.c:1575: dom0: pirq 0 not mapped
[    7.733415] unmap irq failed -22

This patches fixes this and we use the PIRQ value instead of the GSI
value.

cf41a51db8 of/phylib: Use device tree properties to initialize Marvell PHYs.
Some aspects of PHY initialization are board dependent, things like
indicator LED connections and some clocking modes cannot be determined
by probing.  The dev_flags element of struct phy_device can be used to
control these things if an appropriate value can be passed from the
Ethernet driver.  We run into problems however if the PHY connections
are specified by the device tree.  There is no way for the Ethernet
driver to know what flags it should pass.

If we are using the device tree, the struct phy_device will be
populated with the device tree node corresponding to the PHY, and we
can extract extra configuration information from there.

The next question is what should the format of that information be?
It is highly device specific, and the device tree representation
should not be tied to any arbitrary kernel defined constants.  A
straight forward representation is just to specify the exact bits that
should be set using the "marvell,reg-init" property:

      phy5: ethernet-phy@5 {
        reg = <5>;
        compatible = "marvell,88e1149r";
        marvell,reg-init =
                /* led[0]:1000, led[1]:100, led[2]:10, led[3]:tx */
                <3 0x10 0 0x5777>, /* Reg 3,16 <- 0x5777 */
                /* mix %:0, led[0123]:drive low off hiZ */
                <3 0x11 0 0x00aa>, /* Reg 3,17 <- 0x00aa */
                /* default blink periods. */
                <3 0x12 0 0x4105>, /* Reg 3,18 <- 0x4105 */
                /* led[4]:rx, led[5]:dplx, led[45]:drive low off hiZ */
                <3 0x13 0 0x0a60>; /* Reg 3,19 <- 0x0a60 */
      };

      phy6: ethernet-phy@6 {
        reg = <6>;
        compatible = "marvell,88e1118";
        marvell,reg-init =
                /* Fix rx and tx clock transition timing */
                <2 0x15 0xffcf 0>, /* Reg 2,21 Clear bits 4, 5 */
                /* Adjust LED drive. */
                <3 0x11 0 0x442a>, /* Reg 3,17 <- 0442a */
                /* irq, blink-activity, blink-link */
                <3 0x10 0 0x0242>; /* Reg 3,16 <- 0x0242 */
      };

The Marvell PHYs have a page select register at register 22 (0x16), we
can specify any register by its page and register number.  These are
the first and second word.  The third word contains a mask to be ANDed
with the existing register value, and the fourth word is ORed with the
result to yield the new register value.  The new marvell_of_reg_init
function leaves the page select register unchanged, so a call to it
can be dropped into the .config_init functions without unduly
affecting the state of the PHY.

If CONFIG_OF_MDIO is not set, there is no of_node, or no
"marvell,reg-init" property, the PHY initialization is unchanged.

84cf7029b6 qlge: Fix incorrect usage of module parameters and netdev msg level
Driver appears to be mistaking the permission field with default value
in the case of debug and qlge_irq_type.

Driver is also passing debug as a bitmask into netif_msg_init()
which wants a number of bits.  Ron Mercer suggests we should
change this to pass in -1 so the defaults get used instead,
which makes the default much less verbose.

33ac0b84ee atl1c: Fix hardware type check for enabling OTP CLK
Commit 496c185c94 "atl1c: Add support
for Atheros AR8152 and AR8152" added the condition:

             if (hw->nic_type == athr_l1c || hw->nic_type == athr_l2c_b)

for enabling OTP CLK, and the condition:

             if (hw->nic_type == athr_l1c || hw->nic_type == athr_l2c)

for disabling OTP CLK.  Since the two previously defined hardware
types are athr_l1c and athr_l2c, the latter condition appears to be
the correct one.  Change the former to match.

ab08853fab e1000: fix screaming IRQ
VMWare reports that the e1000 driver has a bug when bringing down the
interface, such that interrupts are not disabled in the hardware but the
driver stops reporting that it consumed the interrupt.

The fix is to set the driver's "down" flag later in the routine,
after all the timers and such have exited, preventing the interrupt
handler from being called and exiting early without handling the
interrupt.
