9 years agoremap_file_pages: correctly handle the case of a NULL vm_ops pointer

remap_file_pages: correctly handle the case of a NULL vm_ops pointer

In commit 0b173bc4daa8 ("mm: kill vma flag VM_CAN_NONLINEAR") we
replaced the VM_CAN_NONLINEAR test with checking whether the mapping has
a '->remap_pages()' vm operation, but there is no guarantee that there
it even has a vm_ops pointer at all.

Add the appropriate test for NULL vm_ops.

9 years agokbuild: Fix module signature generation

kbuild: Fix module signature generation

Rusty had clearly not actually tested his module signing changes that I
(trustingly) applied as commit e2a666d52b48 ("kbuild: sign the modules
at install time"). That commit had multiple bugs:

 - using "${#VARIABLE}" to get the number of characters in a shell
   variable may look clever, but it's locale-dependent: it returns the
   number of *characters*, not bytes. And we do need bytes.

   So don't use "${#..}" expansion, do the stupid "wc -c" thing instead
   (where "c" stands for "bytes", not "characters", despite the letter.

 - Rusty had confused "siglen" and "signerlen", and his conversion
   didn't set "signerlen" at all, and incorrectly set "siglen" to the
   size of the signer, not the size of the signature.

End result: the modified sign-file script did create something that
superficially *looked* like a signature, but didn't actually work at
all, and would fail the signature check. Oops.

Tssk, tssk, Rusty.

But Rusty was definitely right that this whole thing should be rewritten
in perl by somebody who has the perl-fu to do so.  That is not me,
though - I'm just doing an emergency fix for the shell script.

   1) There is a major rename at 3.7 (not only uapi changes, but also
      the entire media drivers were reorganized on 3.7, in order to

      it will cause all the harm at for media developers on just one

      welcome it as well, as they won't need to check what changed on
      3.7 and what was postponed for on 3.8.

   2) The V4L2 DocBook Makefile creates a cross-reference between the
      media API headers and the specs.  This helps us _a_lot_ to be sure
      that all API improvements are properly documented.  Every time a

usb: fixes for v3.7-rc2

Here's the first set of fixes for v3.7-rc cycle.

DesignWare Core USB3 Driver (dwc3) got two fixes. The first one fixes a long
standing bug which would keep endpoint with BUSY flag set forever if we cancel
a transfer which has already been started by the controller. The second fix
will just switch PHYs back off when DWC3 driver is removed.

MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when
removing a device. For some reason that particular device can fall into a
situation where you have both Disconnect and Endpoint IRQs happen
simultaneously (have both bits set in IRQ_STATUS register) and, because
Disconnect Interrupt is handled before Endpoint Interrupts, we would try to
transfer data over a disconnected device, thus generating a kernel oops.

Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on
the pipe iterator implementation and b) fixing Interrupt Status Clear procedure
in order to properly clear a single Interrupt event without clearing (and
masking) other events we didn't handle yet.

9 years agocpuidle/powerpc: Fix snooze state problem in the cpuidle design on pseries.
Deepthi Dharwar [Wed, 3 Oct 2012 18:42:26 +0000 (18:42 +0000)]
cpuidle/powerpc: Fix snooze state problem in the cpuidle design on pseries.

Earlier without cpuidle framework on pseries, the native arch
idle routine comprised of both snooze and nap
states.  smt_snooze_delay variable was used to delay
the idle process entry to deeper idle state like  nap.
With the coming of cpuidle, this arch specific idle was replaced
by two different idle routines, one for supporting snooze and other
for nap. This enabled addition of more
low level idle states on pseries in the future.

On adopting the generic cpuidle framework for POWER systems,
the decision of which idle state to choose from,  given a predicted
idle time is taken by the menu governor based on
target_residency and  exit_latency of the idle states.
target_residency is the minimum time to be resident in that idle state.
Exit_latency is time taken to exit out of idle state.
Deeper the idle state, both the target residency and exit latency
would be higher.

In the current design, smt_snooze_delay is used as target_residency
for the  snooze state which is incorrect, as it is not the
minimum but the maximum duration to be in snooze state.
This would  result in the governor in taking bad decision,
as presently target_residency of nap < target_residency of snooze
inspite of nap being deeper idle state.

This patch aims to fix this problem by replacing the smt_snooze_delay loop
in snooze state, with the need_resched()  as the governor is aware of
entry and exit of various idle transitions based on which
next idle time prediction.

The governor is intelligent enough to determine the idle state the needs to
be transitioned to and maintains a whole of heuristics including
io load, previous idle states predictions etc for the same, based on
which idle state entry decision is taken.

With this fix, of setting target_residency of snooze to 0
     nap to smt_snooze_delay
if the predicted idle time is less
than smt_snooze_delay (target_residency of nap)
value governor would pick snooze state, else nap. This adhers to the
previous native idle design.

cpuidle/powerpc: Fix smt_snooze_delay functionality.

smt_snooze_delay was designed to  delay idle loop's nap entry
in the native idle code before it got  ported over to use as part of
the cpuidle framework.

A -ve value  assigned to smt_snooze_delay should result in
busy looping, in other words disabling the entry to nap state.

- https://lists.ozlabs.org/pipermail/linuxppc-dev/2010-May/082450.html

This particular functionality can be achieved currently by
echo 1 > /sys/devices/system/cpu/cpu*/state1/disable

variable either via sysfs entry or ppc64_cpu util.

  (2) Make arch/tile's ucontext.h file use (1) and remove the header-y
      line from the kernel internal side of things.

  (3) Remove some now-empty conditional bits from include/linux/Kbuild.
      The contents got moved to the UAPI side of things along with new
      conditionals.

  (4) Deal with now-empty files:

     (a) Empty Kbuild files under include/ get removed.

     (b) Empty Kbuild files under arch/ get comments to hold them as
         they are likely to end up with generic-y or genhdr-y lines.
         Deleting them appears to work if we want to go that route.

     (c) Put a comment into uapi/asm-generic/kvm_para.h to prevent the
         patch program from deleting that, and made the arches with
         empty kvm_para.h uapi files use that instead of having their
         own files.

     (d) Put comments into four other empty uapi/ headers to prevent the
         patch program from deleting them.

  A question: Is this the right way to deal with the now-empty Kbuild
  files?

  The ones under include/ are unlikely to be used - even for generated
  files, I think - so getting rid of them is probably okay.  Once all
  the bits are in, we can probably remove all the Kbuild files under
  include/ that aren't also under include/uapi/.

  The ones under arch/ are more of an issue because of the potential for
  generic-y and genhdr-y."

they are intentionally left blank.  This would make it easier to add generated
header lines in future without having to restore the infrastructure.

Note that at this point not all the UAPI disintegration parts have been merged,

Fix VLIW packing constraint violation in entry.S:

  arch/frv/kernel/entry.S: Assembler messages:
  arch/frv/kernel/entry.S:871: Error: VLIW packing constraint violation

When packing CALLL with OR, CALLL must go in the first slot.  The
instructions are executed simultaneously, so it doesn't matter which way
round they're packed from that point of view.

9 years agoprintk: Fix scheduling-while-atomic problem in console_cpu_notify()
Paul E. McKenney [Tue, 16 Oct 2012 04:35:59 +0000 (21:35 -0700)]
printk: Fix scheduling-while-atomic problem in console_cpu_notify()

The console_cpu_notify() function runs with interrupts disabled in the
CPU_DYING case.  It therefore cannot block, for example, as will happen
when it calls console_lock().  Therefore, remove the CPU_DYING leg of
the switch statement to avoid this problem.
