a90f56847e [SCSI] lpfc 8.1.9 : Stall eh handlers if resetting while rport blocked
Stall error handler if attempting resets/aborts while an rport is blocked.
This avoids device offline scenarios due to errors in the error handler.

Background:
  Although the transport is using the scsi_timed_out functionality to
  restart the timeout if the rport is blocked, if the timeout has already
  fired before the block occurs, the eh handler still runs and can take
  the device offline. Ultimately, this window cannot be resolved without
  significant work in the error handler thread. Christoph noted the first
  level of these issues when he noted the poor error response handling
  by the error thread.

  We found, under heavy load and error testing, that time window from when
  the scsi_times_out() adds the io to the queue to when the scsi_error_handler
  gets around to servicing it, can be in the several seconds range. In most
  cases, these test conditions are highly unusual, but possible.
  As a result, we're stalling the error handler in this race window so that
  we can avoid the device_offline transitions.

5beba53230 IB/mthca: No userspace SRQs if HCA doesn't have SRQ support
Leave all SRQ methods out of the device's uverbs_cmd_mask if the
device doesn't have SRQ support (because of ancient firmware) so that
we don't allow userspace to call the driver's create_srq method.  This
fixes a userspace-triggerable oops caused by ib_uverbs_create_srq()
following the device's ->create_srq function pointer, which will be
NULL if the device doesn't support SRQs.

  - update state handling in s3c2410_dma_lastxfer
  - only reload in irq if channel is not idle
  - more informative timeout errors (add source)
  - do not call request_irq() with irqs locked
  - added waitforstop function

The patch also adds a S3C2410_DMAOP_STARTED for

2f8af120a1 [BNX2]: Fix tx race condition.
Fix a subtle race condition between bnx2_start_xmit() and bnx2_tx_int()
similar to the one in tg3 discovered by Herbert Xu:

CPU0					CPU1
bnx2_start_xmit()
	if (tx_ring_full) {
		tx_lock
					bnx2_tx()
						if (!netif_queue_stopped)
		netif_stop_queue()
		if (!tx_ring_full)
						update_tx_ring
			netif_wake_queue()
		tx_unlock
	}

Even though tx_ring is updated before the if statement in bnx2_tx_int() in
program order, it can be re-ordered by the CPU as shown above.  This
scenario can cause the tx queue to be stopped forever if bnx2_tx_int() has
just freed up the entire tx_ring.  The possibility of this happening
should be very rare though.

The following changes are made, very much identical to the tg3 fix:

1. Add memory barrier to fix the above race condition.

2. Eliminate the private tx_lock altogether and rely solely on
netif_tx_lock.  This eliminates one spinlock in bnx2_start_xmit()
when the ring is full.

3. Because of 2, use netif_tx_lock in bnx2_tx_int() before calling
netif_wake_queue().

4. Add memory barrier to bnx2_tx_avail().

5. Add bp->tx_wake_thresh which is set to half the tx ring size.

6. Check for the full wake queue condition before getting
netif_tx_lock in tg3_tx().  This reduces the number of unnecessary
spinlocks when the tx ring is full in a steady-state condition.

83db3dde26 [POWERPC] kprobes: Fix possible system crash during out-of-line single-stepping
- On archs that have no-exec support, we vmalloc() a executable scratch
area of PAGE_SIZE and divide it up into an array of slots of maximum
instruction size for that arch
- On a kprobe registration, the original instruction is copied to the
first available free slot, so if multiple kprobes are registered, chances
are, they get contiguous slots
- On POWER4, due to not having coherent icaches, we could hit a situation
where a probe that is registered on one processor, is hit immediately on
another. This second processor could have fetched the stream of text from
the out-of-line single-stepping area *before* the probe registration
completed, possibly due to an earlier (and a different) kprobe hit and
hence would see stale data at the slot.

Executing such an arbitrary instruction lead to a problem as reported
in LTC bugzilla 23555.

The correct solution is to call flush_icache_range() as soon as the
instruction is copied for out-of-line single-stepping, so the correct
instruction is seen on all processors.

Thanks to Will Schmidt who tracked this down.

eac8392f95 [POWERPC] Make secondary CPUs call into kdump on reset exception
In the case of a system hang, the user will invoke soft-reset to
initiate the kdump boot.  If xmon is enabled, the CPU(s) enter into the
xmon debugger.   Unfortunately, the secondary CPU(s) will return to the
hung state when they exit from the debugger (returned from die() ->
system_reset_exception()).  This causes a problem in kdump since the
hung CPU(s) will not respond to the IPI sent from kdump.  This patch
fixes the issue by calling crash_kexec_secondary() directly from
system_reset_exception() without returning to the previous state.  These
secondary CPUs wait 5ms until the kdump boot is started by the primary
CPU.   In the case we exited from the debugger to "recover" (command 'x'
in xmon) the primary and the secondary CPUs will all return from die()
-> system_reset_exception() ->crash_kexec_secondary() wait 5ms, then
return to the previous state.  A kdump boot is not started in this case.

4e6e6504a4 ACPI: Handle BIOS that resumes from S3 to suspend routine rather than resume vector
A BIOS has been found that resumes from S3 to the routine that invoked suspend,
ignoring the resume vector.  This appears to the OS as a failed S3 attempt.

This same system suspend/resume's properly with Windows.

It is possible to invoke the protected mode register restore routine (which
would normally restore the sysenter registers) when the BIOS returns from
S3.  This has no effect on a correctly running system and repairs the
damage from the deviant BIOS.

c9eca0b910 kbuild: correct assingment to CFLAGS with CROSS_COMPILE
Some architectures change $CC in arch/$(ARCH)/Makefile
mips is one example.

That have impact on what options are supported by gcc so move all
$(call cc-option, ...) after include of arch specific Makefile.

acaea9ee46 IB/core: Fix SM LID/LID change with client reregister set
After commit 12bbb2b7be, when SM LID
change or LID change MAD also has a client reregistration bit set,
only CLIENT_REREGISTER event is generated.

As a result, the sa_query module and the cache module don't update the
port information, and ULPs (e.g. IPoIB) stop working.  This is the
regression we observe as compared to 2.6.17.

Rather than generate multiple events (which would have negative
performance impact), let us simply let cache and SA query respond to
reregister event in the same way as to LID and SM change events.

b18a60e7c2 [S390] inaccessible PAV alias devices on LPAR.
In some situations PAV alias devices on LPAR are not accessible.
The initialization procedure required to enable access to PAV alias
devices has to be performed per storage server subsystem and not
only once per storage server.
