BIOS might change frequency behind our back when BIOS changes allowed

Jack Hammer 15084a4a63 [SCSI] ips soft lockup during reset/initialization
Resetting the adapter causes the ServeRAID driver to exceed

A target can LOGO an initiator at any time (i.e. during I/O,
due to a controller hicup, or as a simple authentication
mechanism after an initial CDB command), when this occurs,
the driver attempts to relogin (PLOGI) to the device via the
DPC thread.  Add code to make the appropriate upcall to the
FC transport layer (fc_remote_port_add()) upon successful
completion of the PLOGI.

andrew.vasquez@qlogic.com d97994dc1f [SCSI] qla2xxx: Correct synchronization issues during rport addition/deletion.
The driver can typically detect port-loss during an
interrupt context (i.e. via interrogation of a status IOCB's
completion status [CS_PORT_LOGGED_OUT].  Due to the calling
requirements of the fc_rport APIs, the driver would defer
removal of the device to the default workqueue.  If the
work-item was preceded by an event which caused the port to
obtain visibility (relogin successful, target re-logged into
the topology), deferred removal could inadvertently drop the
rport.  The code also no longer defers removal via the
default workqueue, instead opting for use of the driver's
own DPC thread.

David L Stevens 7add2a4398 [IPV6] MLDv2: fix change records when transitioning to/from inactive
The following patch fixes these problems in MLDv2:

1) Add/remove "delete" records for sending change reports when
        addition of a filter results in that filter transitioning to/from
        inactive. [same as recent IPv4 IGMPv3 fix]
2) Remove 2 redundant "group_type" checks (can't be IPV6_ADDR_ANY
        within that loop, so checks are always true)
3) change an is_in() "return 0" to "return type == MLD2_MODE_IS_INCLUDE".
        It should always be "0" to get here, but it improves code locality 
        to not assume it, and if some race allowed otherwise, doing
        the check would return the correct result.

Nate Diller 248d5ca5ed [BLOCK] elevator: allow default scheduler to potentially be modular
Jens has decided that allowing the default scheduler to be a module is
a bug, and should not be allowed under kconfig.  However, I find that
scenario useful for debugging, and wish for the kernel to be able to
handle this situation without OOPSing, if I enable such an option in
the .config directly.  This patch dynamically checks for the presence
of the compiled-in default, and falls back to no-op, emitting a
suitable error message, when the default is not available

Tested for a range of boot options on 2.6.16-rc1-mm2.

Nate Diller 5f00397644 [BLOCK] elevator: default choice selection
My previous default iosched patch did a poor job dealing with the
'elevator=' boot-time option.  The old behavior falls back to the
compiled-in default if the requested one is not registered at boot
time.  This patch dynamically evaluates which default
to use, and emits a suitable error message when the requested scheduler
is not available.  It also does the 'as' -> 'anticipatory' conversion
before elevator registration, which along with a modified registration
function, allows it to correctly indicate which default scheduler is
in use.

On my latest laptop, I've had occasional PHY dead on wakeup from
sleep... the PHY would be totally unresponsive even to toggling the hard
reset line until the machine is powered down... Looking closely at the
code, I found some possible issues in the way we setup the MDIO lines
during suspend along with slight divergences from what Darwin does when
resetting it that may explain the problem. That patch change these and
the problem appear to be gone for me at least... I also fixed an mdelay
-> msleep while I was at it to the pmac feature code that is called
when toggling the PHY reset line since sungem doesn't call it in an
atomic context anymore.

Alan Cox f91a3715db [SERIAL] 8250 serial console fixes
This patch resolves most of the problems with an SMP serial console race
with output via the tty path. At the end of the serial console print we
force enable the tx int in case we clobbered the tx interrupt status
racing between the console and tty output. That way the extra tx
interrupt causes the transmit path to restart not hang.

It also makes the serial console printk use the FIFO. This is neccessary
because some remote management devices fake serial console with FIFO and
are confused into sending one packet per character over ethernet when we
stall rather than filling the FIFO.

In order to preserve existing reliability semantics the function waits
for the serial queue to completely empty before returning.

Both of these problems were identified by a Red Hat partner.

that uses sub-second select/poll timeout such as emacs.  You
hit a key and it takes a second or so before the app responds.

The two ROUND_UP() calls upon entry are using {tv,ts}_sec where it
should instead be using {tv_usec,ts_nsec}, which perfectly explains
the observed incorrect behavior.
