[SCSI] zfcp: Reduce flood on hba trace
Remove tracing for request with a "qualifier" field set in the
response. The protocol status qualifier now contains measurement
data for "good" commands, so this check would trace every response
by default.
The fix is to simply remove the "qual" tracing: The responses with an
interesting status are also traced as "ferr" or "perr" and all
responses can be traced as "norm" with a higher trace level.

When adding an invalid LUN, there is a deadlock between the add

[SCSI] aacraid: forced reset override
Some of our vendors have requested that our adapters ignore the hardware
reset attempts during recovery and have enforced this with changes in
Adapter Firmware. Some of our customers have requested the option to be
able to reset the adapter under adverse adapter failure, we even had a
few defects reported here considering it a regression that the Adapter
could not be reset. This patch addresses this dichotomy. The user can
force the adapter to be reset if it supports the IOP_RESET_ALWAYS
command, in cases where the adapter has been programmed to ignore the
reset, by setting the aacraid.check_reset parameter to a value of -1.
The driver will not reset an Adapter that does not support the reset
command(s).
This patch also fixes and cleans up some of the logic associated with
resetting the adapter.

ps3fb: fix deadlock on kexec()
Since the introduction of the acquire_console_sem calls in
0333d83509c7d8496c8965b5ba9bc0c98e83c259, kexecing can cause the
kernel to deadlock:
ps3fb_shutdown()
-> unregister_framebuffer()
-> fb_notifier_call_chain(FB_EVENT_FB_UNBIND)
-> fbcon_fb_unbind()
-> unbind_con_driver()
-> bind_con_driver()
[ acquires console_sem ]
-> fbcon_deinit()
-> fbops->fb_release(newinfo, 0)
-> ps3fb_release()
-> ps3fb_sync()
[ acquires console_sem ]
This change avoids the deadlock by moving the acquire_console_sem()
out of ps3fb_sync(), and puts it into the two other callsites, leaving
ps3fb_release() to call ps3fb_sync() without the console semaphore.
[Geert]
- Corrected call sequence above
- ps3fb_release() may be called with and without console_sem held. This is an
inconsistency that should be fixed at the fb level, but for now, try to
acquire console_sem in ps3fb_release().
I think it's safer to let ps3fb_release() try to acquire console_sem and
not refresh the screen if it fails, than to call ps3fb_sync() without
holding console_sem, as ps3fb_par may be modified at the same time, causing
crashes or lockups.
Besides, ps3fb_release() only calls ps3fb_sync() to refresh the screen
when display flipping is disabled, which is an uncommon case (except during
shutdown/kexec).

[MIPS] Malta: Fix software reset on big endian
I noticed that the commit
f197465384bf7ef1af184c2ed1a4e268911a91e3
(MIPS Tech: Get rid of volatile in core code) broke the software
reset functionality for MIPS Malta boards in big-endian mode.
According to the MIPS Malta board user's manual, writing the magic
32-bit GORESET value into the SOFTRES register initiates board soft
reset. My experimentation has shown that the endianness of the GORESET
integer should thereby be the same as the endianness, which has been
set for the CPU itself. The writew() function used to write the magic
value in the code introduced by the commit mentioned above, however,
swaps bytes for big-endian kernels and transfers 16 bits instead of 32.
The patch below replaces the writew() function by the __raw_writel()
routine, which leaves the byte order intact and transfers the whole
MIPS machine word. Trivial code cleanup (replacing spaces by a tab
and cutting oversized lines to make checkpatch.pl happy) is also
included.
The patch was tested using a Malta evaluation board running in both
BE and LE modes. For both modes, software reset was fully functional
after the change.
P.S. I suspect that the same commit broke the "standby" functionality
for MIPS Atlas boards. However, I did not touch the Atlas code as I
don't have such board at my disposal and also because the linux-mips.org
Web site claims that Atlas support is scheduled for removal.

libata: don't normalize UNKNOWN to NONE after reset
After non-classifying reset, ehc->classes[] could contain
ATA_DEV_UNKNOWN which used to be normalized to ATA_DEV_NONE for
consistency. However, this causes unfortunate side effect for drivers
which have non-classifying hardresets (e.g. sata_nv) by making
hardreset report ATA_DEV_NONE for non-classifying resets and thus
makes EH believe that the port is unoccupied and recovery can be
skipped. The end result is that after a device is swapped with
another one, the new device isn't attached after the old one is
detached.
This patch makes ata_eh_reset() not normalize UNKNOWN to NONE after
non-classifying resets. This fixes the above problem. As UNKNOWN and
NONE are handled differently by only EH hotplug logic, this doesn't

[ATM]: Check IP header validity in mpc_send_packet
Al went through the ip_fast_csum callers and found this piece of code
that did not validate the IP header. While root crashing the machine
by sending bogus packets through raw or AF_PACKET sockets isn't that
serious, it is still nice to react gracefully.
This patch ensures that the skb has enough data for an IP header and
that the header length field is valid.

[XFRM]: xfrm_algo_clone() allocates too much memory
alg_key_len is the length in bits of the key, not in bytes.
Best way to fix this is to move alg_len() function from net/xfrm/xfrm_user.c
to include/net/xfrm.h, and to use it in xfrm_algo_clone()
alg_len() is renamed to xfrm_alg_len() because of its global exposition.

[FORCEDETH]: Fix reversing the MAC address on suspend.
For cards that initially have the MAC address stored in reverse order,
the forcedeth driver uses a flag to signal whether the address was
already corrected, so that it is not reversed again on a subsequent
probe.
Unfortunately this flag, which is stored in a register of the card,
seems to get lost during suspend, resulting in the MAC address being
reversed again. To fix that, the MAC address needs to be written back
in reversed order before we suspend and the flag needs to be reset.
The flag is still required because at least kexec will never write
back the reversed address and thus needs to know what state the card
is in.

[NET]: Clone the sk_buff 'iif' field in __skb_clone()
Both NetLabel and SELinux (other LSMs may grow to use it as well) rely
on the 'iif' field to determine the receiving network interface of
inbound packets. Unfortunately, at present this field is not
preserved across a skb clone operation which can lead to garbage
values if the cloned skb is sent back through the network stack. This
patch corrects this problem by properly copying the 'iif' field in
__skb_clone() and removing the 'iif' field assignment from
skb_act_clone() since it is no longer needed.
Also, while we are here, put the assignments in the same order as the
offsets to reduce cacheline bounces.
