The old interface is bugged and reads the wrong sensor when retrieving
the reading for the chassis fan (it reads the CPU sensor); the new
interface works fine.

On OMAP4, if the first CPU fails to get a valid frequency table (this
could happen if the platform does not register any OPP table), the
subsequent CPU instances end up dealing with a NULL freq_table and
crash.
Check for an already existing freq_table, before trying to create one,
and increment the freq_table_users only if the table is sucessfully
created.

This reverts commit 00e37bdb0113a98408de42db85be002f21dbffd3.
During shutdown of PVHVM guests with more than 2VCPUs on certain
machines we can hit the race where the replaced shared_info is not
replaced fast enough and the PV time clock retries reading the same
area over and over without any any success and is stuck in an
infinite loop.

BCM6338 and BCM6348 have a message control register width of 8 bits, instead
of 16-bits like what the SPI driver assumes right now. Also the SPI message
type shift value of 14 is actually 6 for these SoCs.
This resulted in transmit FIFO corruption because we were writing 16-bits
to an 8-bits wide register, thus spanning on the first byte of the transmit
FIFO, which had already been filed in bcm63xx_spi_fill_txrx_fifo().
Fix this by passing the message control register width and message type
shift through platform data back to the SPI driver so that it can use
it properly.

Fengguang.
- Abstract out the mapping of a bio in a request, and use that to
provide a blk_bio_map_sg() helper. Useful for mapping just a bio
instead of a full request.
- Regression fix from Hugh, fixing up a patch that went into the
previous release cycle (and marked stable, too) attempting to prevent
a loop in __getblk_slow().
- Updates to discard requests, fixing up the sizing and how we align
them. Also a change to disallow merging of discard requests, since
that doesn't really work properly yet.

We need to write the whole bitmap after we moved the meta data
due to an online resize operation.
With the support for one peta byte devices bitmap IO was optimized
to only write out touched pages. This optimization must be turned
off when writing the bitmap after an online resize.
This issue was introduced with drbd-8.3.10.
The impact of this bug is that after an online resize, the next
resync could become larger than expected.

Requests of an acked epoch are stored on the barrier_acked_requests list. In
case the private bio of such a request completes while IO on the drbd device
is suspended [req_mod(completed_ok)] then the request stays there.
When thawing IO because the fence_peer handler returned, then we use
tl_clear() to apply the connection_lost_while_pending event to all requests
on the transfer-log and the barrier_acked_requests list.
Up to now the connection_lost_while_pending event was not applied
on requests on the barrier_acked_requests list. Fixed that.
I.e. now the connection_lost_while_pending and resend events are
applied to requests on the barrier_acked_requests list. For that
it is necessary that the resend event finishes (local only)
READS correctly.

DRBD has a concept of request epochs or reorder-domains,
which are separated on the wire by P_BARRIER packets.
Older DRBD is not able to handle zero-sized requests at all,
so we need to map empty flushes to these drbd barriers.
These are the equivalent of empty flushes, and
by default trigger flushes on the receiving side anyways
(unless not supported or explicitly disabled),
so there is no need to handle this differently in newer drbd either.

I have an external SATA drive that was slowed down by bridge limits. I
found a solution in a thread on this list posted in 2008: It introduces
whitelist entries in libata-core.c for devices with well working bridges
(e.g. email on Fri, 31 Oct 2008 01:45:27 -0400).
I added my device to this whitelist in a custom built kernel and it
works fine for weeks now. How can I have this device added on the
whitelist within the official kernel? Is this whitelist mechanism still
supported or is there a smarter way to achieve whitelisting?
I added the following whitelist entry for my Buffalo DriveStation
Quattro "BUFFALO HD-QSU2/R5":

I followed the advice to not use the deprecated old PATA subsystem
ATA/ATAPI/MFM/RLL support (DEPRECATED) --->
and use the ATA subsystem instead.
Serial ATA and Parallel ATA drivers --->
Unfortunately I needed several tries to find out, that I needed the SFF
menu I had not selected before because I had never heard that term
before. I think it would have helped me, to have PATA or legacy IDE in
that item’s name.

Commit 30dcf76acc695cbd2fa919e294670fe9552e16e7 mistakenly dropped
the code to get an initial gtm for the IDE channel. This caused the
following problem for Sergei:
http://marc.info/?l=linux-kernel&m=134484963618457&w=2
Fix this by adding the call back in ata_acpi_bind_host, and due to
this, the ata_ap_acpi_handle is modified accordingly.

The mainboard MSI E350DM-E33 is advertised with 6 SATA ports.
As it turns out, two of them seem to be driven by on-board
SATA<->PATA converters. If a disk drive is connected to one
of them kernel uses UDMA/33 mode due to cable detection:
[ 34.550823] scsi4 : pata_atiixp
[ 34.555517] scsi5 : pata_atiixp
[ 34.555942] ata5: PATA max UDMA/100 cmd 0x1f0 ctl 0x3f6 bmdma 0xf100 irq 14
[ 34.555948] ata6: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0xf108 irq 15
...
[ 35.040799] ata5.00: ATA-8: WDC WD20EADS-00R6B0, 01.00A01, max UDMA/133
[ 35.040806] ata5.00: 3907029168 sectors, multi 16: LBA48 NCQ (depth 0/32)
[ 35.040817] ata5.00: limited to UDMA/33 due to 40-wire cable

[ 35.049402] scsi 4:0:0:0: Direct-Access ATA WDC WD20EADS-00R 01.0 PQ: 0 ANSI: 5
This patch forces "short cable" mode on this board, as it seems clear that
the on-board SATA<->PATA "cable" is short.
With this patch the disk is configured for UDMA/100:
[ 5.976756] ata5.00: ATA-8: WDC WD20EADS-00R6B0, 01.00A01, max UDMA/133
[ 5.996434] ata5.00: 3907029168 sectors, multi 16: LBA48 NCQ (depth 0/32)
[ 6.024787] ata5.00: configured for UDMA/100

commit "crypto: caam - use non-irq versions of spinlocks for job rings"
made two bad assumptions:
(a) The caam_jr_enqueue lock isn't used in softirq context.
Not true: jr_enqueue can be interrupted by an incoming net
interrupt and the received packet may be sent for encryption,
via caam_jr_enqueue in softirq context, thereby inducing a
deadlock.
This is evidenced when running netperf over an IPSec tunnel
between two P4080's, with spinlock debugging turned on:

(b) since the caam_jr_dequeue lock is only used in bh context,
then semantically it should use _bh spin_lock types. spin_lock_bh
semantics are to disable back-halves, and used when a lock is shared
between softirq (bh) context and process and/or h/w IRQ context.
Since the lock is only used within softirq context, and this tasklet
is atomic, there is no need to do the additional work to disable
back halves.
This patch adds back-half disabling protection to caam_jr_enqueue
spin_locks to fix (a), and drops it from caam_jr_dequeue to fix (b).

Commit feb7b7ab928afa97a79a9c424e4e0691f49d63be changed NSEC_PER_SEC to 64-bit
constant, which causes "DIV_ROUND_UP(NSEC_PER_SEC, dev->pk_clk_freq)" to
generate __divdi3 call on 32-bit archs. Fix this by changing DIV_ROUND_UP to
DIV_ROUND_UP_ULL.

This patch fixes a regresion introduced by commit 0998d063 (device-core: Ensure
drvdata = NULL when no driver is bound).
Suspend oopses in generic_ide_suspend() because dev_get_drvdata()
returns NULL (dev->p->driver_data == NULL) and this function is not
prepared for this.
Fix is based on Alan Stern's suggestion.

This QUANTA device is driven by the generic hid-multitouch.ko driver, and
therefore shouldn't be in the special drivers list.
This has been an oversight in 4fa3a58 ("HID: hid-multitouch: Switch to

So we've had a fair few reports of fbcon handover breakage between
efi/vesafb and i915 surface recently, so I dedicated a couple of
days to finding the problem.
Essentially the last thing we saw was the conflicting framebuffer
message and that was all.
So after much tracing with direct netconsole writes (printks
under console_lock not so useful), I think I found the race.
Thread A (driver load) Thread B (timer thread)
unbind_con_driver -> |
bind_con_driver -> |
vc->vc_sw->con_deinit -> |
fbcon_deinit -> |
console_lock() |
| |
| fbcon_flashcursor timer fires
| console_lock() <- blocked for A
|
|
fbcon_del_cursor_timer ->
del_timer_sync
(BOOM)
Of course because all of this is under the console lock,
we never see anything, also since we also just unbound the active
console guess what we never see anything.
Hopefully this fixes the problem for anyone seeing vesafb->kms
driver handoff.
v1.1: add comment suggestion from Alan.

If you do a page flip with no flags set then event is NULL. If event is
NULL then the vmw_gfx driver likes to go digging into NULL and extracts
NULL->base.file_priv.
On a modern kernel with NULL mapping protection it's just another oops,
without it there are some "intriguing" possibilities.
What it should do is an open question but that for the driver owners to
sort out.

James Bottomley reported [1] a massive power regression, due to the
enabling of semaphores by default in 3.5. A workaround for him is to
again disable semaphores. And indeed, his system has a very hard time
to enter rc6 with semaphores enabled.
Ben Widawsky run around with a kill-a-watt a lot and noticed:
- There are indeed a few rare systems that seem to have a hard time
entering rc6 when desktop-idle.
- One machine, The Indestructible Toshiba regressed in this behaviour
between 3.5 and 3.6 in a merge commit! So rc6 behaviour with the
current setting seems to be highly timing dependent and not robust
at all.
- The behaviour James reported wrt semaphores seems to be a freak
timing thing that only happens on his specific machine, confirming
that enabling semaphores shouldn't reduce rc6 residency.
Now furthermore the Google ChromeOS guys reported [2] a while ago that
at least on some machines a simply a blinking cursor can keep the gpu
turbo at the highest frequency. This is because the current rps limits
used on snb/ivb are highly asymmetric.
On the theory that gpu turbo and rc6 tuning values are related, we've
tried whether the much saner looking (since much less asymmetric) rps
tuning values used for hsw would also help entering rc6 more robustly.
And it seems to mostly work, and we don't really have the resources to
through-roughly tune things in any better way: The values from the
ChromeOS ppl seem to fare a bit worse for James' machine, so I guess
we better stick with something vpg (the gpu hw/windows group)
provided, hoping that they've done their jobs.

After reset we unconditionally reinitialize lists. If the context switch
hasn't yet completed before the suspend, the default context object will
end up on lists that are going to go away when we resume.
The patch forces the context switch to be synchronous before suspend
assuring that the active/inactive tracking is correct at the time of
resume.

This reverts commit d1c7871ddb1f588b8eb35affd9ee1a3d5e11cd0c.
ttm_bo_init() destroys the BO on failure. So this patch makes
the retry path work with freed memory. This ends up causing
kernel panics when this path is hit.
