4459f3974a Sound fixes for 3.6-rc3
This update became slightly bigger than usual for rc3, but most of the
 commits are small and trivial.  A large chunk is found for HD-audio
 ca0132 codec, which is mostly a clean up of the specific code, to make
 SPDIF working properly, and also in the new ASoC Arizona driver.
 
 One important fix is for usb-audio Oops fix since 3.5.  We still see
 some EHCI related bandwidth problem, but usb-audio should be more
 stabilized now.
 
 Other than that, a Kconfig fix is spread over files, and various
 HD-audio and ASoC fixes as usual, in addition to Julia's error path
 fixes.

f341861fb0 task_work: add a scheduling point in task_work_run()
It seems commit 4a9d4b024a ("switch fput to task_work_add") re-
introduced the problem addressed in 944be0b224 ("close_files(): add
scheduling point")

If a server process with a lot of files (say 2 million tcp sockets) is
killed, we can spend a lot of time in task_work_run() and trigger a soft
lockup.

ec5da7f8dc fbcon: fix race condition between console lock and cursor timer
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.

snd_card_als100_probe() does not set pcm field in struct snd_sb.
As a result, PCM is not suspended and applications don't know that they need
to resume the playback.

Tested with Labway A381-F20 card (ALS120).

d408ea2a0d IOMMU Fixes for Linux v3.6-rc2
Two fixes are necessary. One patch fixes a boot crash on MacBook Air
 with interrupt remapping enabled and the other patch fixes a regression
 (which causes a boot crash on AMD IOMMUv2 systems too) in the init code
 of the AMD IOMMU driver.

8f057d7bca gpu/mfd/usb: Fix USB randconfig problems
Fix config warning:

warning: ( ... && DRM_USB) selects USB which has unmet direct dependencies
(USB_SUPPORT && USB_ARCH_HAS_HCD)

and build error:
ERROR: "usb_speed_string" [drivers/usb/core/usbcore.ko] undefined!

by adding the missing dependency on USB_ARCH_HAS_HCD to DRM_UDL and DRM_USB.

This exposes:
drivers/video/Kconfig:36:error: recursive dependency detected!
drivers/video/Kconfig:36:       symbol FB is selected by DRM_KMS_HELPER
drivers/gpu/drm/Kconfig:28:     symbol DRM_KMS_HELPER is selected by DRM_UDL
drivers/gpu/drm/udl/Kconfig:1:  symbol DRM_UDL depends on USB_ARCH_HAS_HCD

drivers/video/Kconfig:86:       symbol FB_DDC is selected by FB_CYBER2000_DDC
drivers/video/Kconfig:385:      symbol FB_CYBER2000_DDC depends on FB_CYBER2000
drivers/video/Kconfig:373:      symbol FB_CYBER2000 depends on FB

which is due to drivers/usb/Kconfig:
config USB_ARCH_HAS_OHCI
	...
	default y if ARCH_PNX4008 && I2C

Fix by dropping I2C from the above dependency; logic is that this is not a
platform dependency but a configuration dependency: the _architecture_ still
supports USB even is I2C is not selected.

This exposes:
drivers/video/Kconfig:36:error: recursive dependency detected!
drivers/video/Kconfig:36:       symbol FB is selected by DRM_KMS_HELPER

drivers/gpio/Kconfig:35:        symbol GPIOLIB is selected by FB_VIA
drivers/video/Kconfig:1560:     symbol FB_VIA depends on FB

which can be fixed by having MFD_TC6393XB select GPIOLIB instead of depending on

The following build error occurred during an alpha build:

  net/core/sock.c:274:36: error: initializer element is not constant

Dave Anglin says:
> Here is the line in sock.i:
>
> struct static_key memalloc_socks = ((struct static_key) { .enabled =
> ((atomic_t) { (0) }) });

The above line contains two compound literals.  It also uses a designated
initializer to initialize the field enabled.  A compound literal is not a
constant expression.

The location of the above statement isn't fully clear, but if a compound
literal occurs outside the body of a function, the initializer list must
consist of constant expressions.

After commit ec2212088c ("Disintegrate asm/system.h for Alpha"), the
fpu.h header which we install for userland started depending on
special_insns.h which is not installed.

However, fpu.h only uses that for __KERNEL__ code, so protect the
inclusion the same way to avoid build breakage in glibc:

  /usr/include/asm/fpu.h:4:31: fatal error: asm/special_insns.h: No such file or directory

0bcc426b1d alpha/mm/fault.c: Port OOM changes to do_page_fault
Commit d065bd810b ("mm: retry page fault when blocking on disk
transfer") and 37b23e0525 ("x86,mm: make pagefault killable")
introduced changes into the x86 pagefault handler for making the page
fault handler retryable as well as killable.

These changes reduce the mmap_sem hold time, which is crucial during OOM
killer invocation.

Port these changes to ALPHA.

be53db6e4e alpha: take a bunch of syscalls into osf_sys.c
New helper: current_thread_info().  Allows to do a bunch of odd syscalls
in C. While we are at it, there had never been a reason to do
osf_getpriority() in assembler.  We also get "namespace"-aware (read:
consistent with getuid(2), etc.) behaviour from getx?id() syscalls now.

f2db633d30 alpha: Use new generic strncpy_from_user() and strnlen_user()
Similar to x86/sparc/powerpc implementations except:
1) we implement an extremely efficient has_zero()/find_zero()
   sequence with both prep_zero_mask() and create_zero_mask()
   no-operations.
2) Our output from prep_zero_mask() differs in that only the
   lowest eight bits are used to represent the zero bytes
   nevertheless it can be safely ORed with other similar masks
   from prep_zero_mask() and forms input to create_zero_mask(),
   the two fundamental properties prep_zero_mask() must satisfy.

Tests on EV67 and EV68 CPUs revealed that the generic code is
essentially as fast (to within 0.5% of CPU cycles) of the old
Alpha specific code for large quadword-aligned strings, despite
the 30% extra CPU instructions executed.  In contrast, the
generic code for unaligned strings is substantially slower (by
more than a factor of 3) than the old Alpha specific code.

a2fa3ccd7b alpha: Don't export SOCK_NONBLOCK to user space.
Currently we export SOCK_NONBLOCK to user space but that conflicts with
the definition from glibc leading to compilation errors in user programs
(e.g.  see Debian bug #658460).

The generic socket.h restricts the definition of SOCK_NONBLOCK to the
kernel, as does the MIPS specific socket.h, so let's do the same on
Alpha.

Pull ARM fixes from Russell King:
 "The largest thing in this set of changes is bringing back some of the
  ARMv3 code to fix a compile problem noticed on RiscPC, which we still
  support, even though we only support ARMv4 there.

  (The reason is that the system bus doesn't support ARMv4 half-word
  accesses, so we need the ARMv3 library code for this platform.)

  The rest are all quite minor fixes."
