Arjan van de Ven [Mon, 24 Nov 2008 00:57:36 +0000]
input: replace spin_lock_bh with spin_lock_irqsave in ml_ff_playback

ml_ff_playback() uses spin_(un)lock_bh. However this function is called
with interrupts disabled from erase_effect() in drivers/input/ff-core.c:196.

This is not permitted, and will result in a WARN_ON in the bottom half handling code.
This patch changes this function to just use spin_lock_irqsave() instead, solving
the problem and simplifying the locking logic.

11 years agotricky one: hisax sections
Al Viro [Sat, 22 Nov 2008 17:36:54 +0000]
tricky one: hisax sections

a) hisax_init_pcmcia() needs to be defined only if we have
   CONFIG_HOTPLUG (no PCMCIA support otherwise) and can be declared
   __devinit.

b) HiSax_inithardware() can go __init

c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card():
checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card);
   The problem with it is that
* hisax_cs_setup_card() is __devinit
* hisax_register() is not
* hisax_cs_setup_card() is a switch from hell, calling a lot of
  setup_some_weirdcard() depending on card->typ.  _These_ are also
  __devinit.

   However, in hisax_register() we have card->typ equal to
   ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind
   all that crap, just do nothing and return 2".  So we add a
   trimmed-down callback doing just that and passed to checkcard() by
   hisax_register().  _This_ is non-init (we can stand the impact on
   .text size).

The code

in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to

in the same failure case handling, it calls the exit function, which also
frees the rfkill state, but after stopping the polling.

If the race happens, a NULL pointer is passed to rfkill_force_state()
which then causes a nice dereference.

Fix the race by just not doing the too-early freeing of the rfkill state.

This appears to be the cause of a hot issue on kerneloops.org; while I
have no solid evidence of that this patch will fix the issue, the race
appears rather real.

..

The s390 implementation of sched_clock uses the store clock instruction and
subtracts jiffies_timer_cc.
jiffies_timer_cc is a local variable in arch/s390/kernel/time.c and only used
for sched_clock and monotonic clock. For historical reasons there is an offset
on that value. With todays code this offset is unnecessary. By removing that
offset we can get a sched_clock which returns the nanoseconds after time_init.
This improves CONFIG_PRINTK_TIME.

Since sched_clock is the only user, I have also renamed jiffies_timer_cc to
sched_clock_base_cc. In addition, the local variable init_timer_cc is redundant
and can be romved as well.

Martin Schwidefsky [Thu, 27 Nov 2008 10:05:55 +0000]
[S390] fix system call parameter functions.

syscall_get_nr() currently returns a valid result only if the call
chain of the traced process includes do_syscall_trace_enter(). But
collect_syscall() can be called for any sleeping task, the result of
syscall_get_nr() in general is completely bogus.

To make syscall_get_nr() work for any sleeping task the traps field
in pt_regs is replace with svcnr - the system call number the process
is executing. If svcnr == 0 the process is not on a system call path.

The syscall_get_arguments and syscall_set_arguments use regs->gprs[2]
for the first system call parameter. This is incorrect since gprs[2]
may have been overwritten with the system call number if the call
chain includes do_syscall_trace_enter. Use regs->orig_gprs2 instead.

Henrique de Moraes Holschuh [Sun, 9 Nov 2008 12:54:02 +0000]
ACPI: thinkpad-acpi: fix fan sleep/resume path

This fixes a regression from v2.6.27, caused by commit
5814f737e1cd2cfa2893badd62189acae3e1e1fd, "ACPI: thinkpad-acpi:
attempt to preserve fan state on resume".

It is possible for fan_suspend() to fail to properly initialize
fan_control_desired_level as required by fan_resume(), resulting on
the fan always being set to level 7 on resume if the user didn't
touch the fan controller.

In order to get fan sleep/resume handling to work right:

1. Fix the fan_suspend handling of the T43 firmware quirk. If it is
still undefined, we didn't touch the fan yet and that means we have no
business doing it on resume.

2. Store the fan level on its own variable to avoid any possible
issues with hijacking fan_control_desired_level (which isn't supposed
to have anything other than 0-7 in it, anyway).

3. Change the fan_resume code to me more straightforward to understand
(although we DO optimize the boolean logic there, otherwise it looks
disgusting).

4. Add comments to help understand what the code is supposed to be
doing.

5. Change fan_set_level to be less strict about how auto and
full-speed modes are requested.

ACPI suspend: Blacklist boxes that require us to set SCI_EN directly on resume

Some Apple boxes evidently require us to set SCI_EN on resume
directly, because if we don't do that, they hung somewhere in the
resume code path.  Moreover, on these boxes it is not sufficient to
use acpi_enable() to turn ACPI on during resume.  All of this is
against the ACPI specification which states that (1) the BIOS is
supposed to return from the S3 sleep state with ACPI enabled
(SCI_EN set) and (2) the SCI_EN bit is owned by the hardware and we
are not supposed to change it.

For this reason, blacklist the affected systems so that the SCI_EN
bit is set during resume on them.

[NOTE: Unconditional setting SCI_EN for all system on resume doesn't
 work, because it makes some other systems crash (that's to be
 expected).  Also, it is not entirely clear right now if all of the

The AFG pin power-mapping isn't properly set for the fixed I/O pins
on IDT 92HD* codecs.  This resulted in the low power mode after the
boot until any jack detection is executed, thus no output from the
speaker.

This patch fixes the power mapping for the fixed pins, and also fixes
the GPIO bits and digital I/O pin settings properly in stac92xx_ini().

ALSA: hda - Fix caching of SPDIF status bits

SPDIF status bits controls are written via snd_hda_codec_write()
without caching.  This causes a regression at resume that the bits
are lost.

Simply replacing it with the cached version fixes the problem.

11 years agoInput: replace spin_lock_bh with spin_lock_irqsave in ml_ff_playback
Arjan van de Ven [Mon, 24 Nov 2008 03:35:57 +0000]
Input: replace spin_lock_bh with spin_lock_irqsave in ml_ff_playback

ml_ff_playback() uses spin_(un)lock_bh. However this function is
called with interrupts disabled from erase_effect() in
drivers/input/ff-core.c:196.

This is not permitted, and will result in a WARN_ON in the bottom
half handling code. This patch changes this function to just use
spin_lock_irqsave() instead, solving the problem and simplifying
the locking logic.

11 years agoMIPS: Make BUG() __noreturn.
David Daney [Fri, 21 Nov 2008 01:26:36 +0000]
MIPS: Make BUG() __noreturn.

Often we do things like put BUG() in the default clause of a case
statement.  Since it was not declared __noreturn, this could sometimes
lead to bogus compiler warnings that variables were used
uninitialized.

There is a small problem in that we have to put a magic while(1); loop to
fool GCC into really thinking it is noreturn.  This makes the new
BUG() function 3 instructions long instead of just 1, but I think it
is worth it as it is now unnecessary to do extra work to silence the
'used uninitialized' warnings.

I also re-wrote BUG_ON so that if it is given a constant condition, it
just does BUG() instead of loading a constant value in to a register
and testing it.

[IA64] Rationalize kernel mode alignment checking

Itanium processors can handle some misaligned data accesses. They
also provide a mode where all such accesses are forced to trap. The
kernel was schizophrenic about use of this mode:

* Base kernel code ran in permissive mode where the only traps
  generated were from those cases that the h/w could not handle.
* Interrupt, syscall and trap code ran in strict mode where all
  unaligned accesses caused traps to the 0x5a00 unaligned reference
  vector.

Use strict alignment checking throughout the kernel, but make
sure that we continue to let user mode use more relaxed mode
as the default.

x86: Fix interrupt leak due to migration

When we migrate an interrupt from one CPU to another, we set the
move_in_progress flag and clean up the vectors later once they're not
being used.  If you're unlucky and call destroy_irq() before the vectors
become un-used, the move_in_progress flag is never cleared, which causes
the interrupt to become unusable.

This was discovered by Jesse Brandeburg for whom it manifested as an
MSI-X device refusing to use MSI-X mode when the driver was unloaded
and reloaded repeatedly.

SUNRPC: Fix a performance regression in the RPC authentication code

Fix a regression reported by Max Kellermann whereby kernel profiling
showed that his clients were spending 45% of their time in
rpcauth_lookup_credcache.

It turns out that although his processes had identical uid/gid/groups,
generic_match() was failing to detect this, because the task->group_info
pointers were not shared. This again lead to the creation of a huge number
of identical credentials at the RPC layer.

The regression is fixed by comparing the contents of task->group_info
if the actual pointers are not identical.

The problem is that compat_arch_ptrace() enters with an addr value of
type compat_ulong_t and calls translate_usr_offset() to translate the
address offset into a struct pt_regs offset like this:

addr = translate_usr_offset(addr)

this means that any return value of translate_usr_offset() is stored
back as compat_ulong_t type into the addr variable.

But since translate_usr_offset() returns -1 for invalid offsets, addr
can now get the value 0xffffffff which then fails the next return-value
sanity check and thus the kernel tries to access invalid memory:

if (addr < 0)
break;

Fix this bug by modifying translate_usr_offset() to take and return
values of type compat_ulong_t, and by returning the value
"sizeof(struct pt_regs)" as an error indicator.

Additionally change the sanity check to check for return values
for >= sizeof(struct pt_regs).

This patch survived my compile and run-tests.

MIPS: RB532: Provide functions for gpio configuration

As gpiolib doesn't support pin multiplexing, it provides no way to
access the GPIOFUNC register. Also there is no support for setting
interrupt status and level. These functions provide access to them and
are needed by the CompactFlash driver.

MIPS: IP22: Make indy_sc_ops variable static

The indy_sc_ops variable in arch/mips/mm/sc-ip22.c is needlessly defined
global, and this patch makes it static.

MIPS: RB532: GPIO register offsets are relative to GPIOBASE

This patch fixes the wrong use of GPIO register offsets
in devices.c. To avoid further problems, use gpio_get_value
to return the NAND status instead of our own expanded code.

Also define the zero offset of the alternate function register to allow
consistent access.

MIPS: Malta: Fix include paths in malta-amon.c

On linux-queue, malta doesn't build after the include file relocation.
This should fix it.

There some occurrences of 'asm-mips' in the comments of quite a few
files, but this is the only place I found it in any code.
