'asoc/fix/si476x' into asoc-linus
|
|
|
|
The 88pm860 is a MFD device and the CODEC driver is using the regmap struct of
the parent device, hence automatic IO setup will not work and we need to
manually call snd_soc_codec_set_cache_io(). The issue was introduced in commit
f9ded3b2e7 ("ASoC: 88pm860x: Use regmap for I/O").

In the first place, the loop 'for' in the macro 'for_each_isci_host'
(drivers/scsi/isci/host.h:314) is incorrect, because it accesses
the 3rd element of 2 element array. After the 2nd iteration it executes
the instruction:
ihost = to_pci_info(pdev)->hosts[2]
(while the size of the 'hosts' array equals 2) and reads an
out of range element.
In the second place, this loop is incorrectly optimized by GCC v4.8
(see http://marc.info/?l=linux-kernel&m=138998871911336&w=2).
As a result, on platforms with two SCU controllers,
the loop is executed more times than it can be (for i=0,1 and 2).
It causes kernel panic during entering the S3 state
and the following oops after 'rmmod isci':

Remove an erroneous BUG_ON() in the case of a hard reset timeout. The
reset timeout handler puts the port into the "awaiting link-up" state.
The timeout causes the device to be disconnected and we need to be in
the awaiting link-up state to re-connect the port. The BUG_ON() made
the incorrect assumption that resets never timeout and we always
complete the reset in the "resetting" state.
Testing this patch also uncovered that libata continues to attempt to
reset the port long after the driver has torn down the context. Once
the driver has committed to abandoning the link it must indicate to
libata that recovery ends by returning -ENODEV from
->lldd_I_T_nexus_reset().

This fixes requesting of the MSI-X vectors for the base response queue.
The iteration in the for loop in qla24xx_enable_msix() was incorrect.
We should only iterate of the first two MSI-X vectors and not the total
number of MSI-X vectors that have given to the driver for this device
from pci_enable_msix() in this function.

This fixes CVE-2014-0102.
The following command sequence produces an oops:
keyctl new_session
i=`keyctl newring _ses @s`
keyctl link @s $i
The problem is that search_nested_keyrings() sees two keyrings that have
matching type and description, so keyring_compare_object() returns true.
s_n_k() then passes the key to the iterator function -
keyring_detect_cycle_iterator() - which *should* check to see whether this is
the keyring of interest, not just one with the same name.
Because assoc_array_find() will return one and only one match, I assumed that
the iterator function would only see an exact match or never be called - but
the iterator isn't only called from assoc_array_find()...
The oops looks something like this:
kernel BUG at /data/fs/linux-2.6-fscache/security/keys/keyring.c:1003!
invalid opcode: 0000 [#1] SMP
...
RIP: keyring_detect_cycle_iterator+0xe/0x1f
...
Call Trace:
search_nested_keyrings+0x76/0x2aa
__key_link_check_live_key+0x50/0x5f
key_link+0x4e/0x85
keyctl_keyring_link+0x60/0x81
SyS_keyctl+0x65/0xe4
tracesys+0xdd/0xe2
The fix is to make keyring_detect_cycle_iterator() check that the key it
has is the key it was actually looking for rather than calling BUG_ON().
A testcase has been included in the keyutils testsuite for this:
http://git.kernel.org/cgit/linux/kernel/git/dhowells/keyutils.git/commit/?id=891f3365d07f1996778ade0e3428f01878a1790b

The pci shutdown handler added in:
bnx2: Add pci shutdown handler
commit 25bfb1dd4ba3b2d9a49ce9d9b0cd7be1840e15ed
created a shutdown down sequence without chip reset if the device was
never brought up. This can cause the firmware to shutdown the PHY
prematurely and cause MMIO read cycles to be unresponsive. On some
systems, it may generate NMI in the bnx2's pci shutdown handler.
The fix is to tell the firmware not to shutdown the PHY if there was
no prior chip reset.

Pull ACPI and power management fixes from Rafael Wysocki:
- ACPI tables in some BIOSes list device resources with size equal to
0, which doesn't make sense, so we should ignore them, but instead we
try to use them and mangle things completely. Fix from Zhang Rui.
- Several models of Samsung laptops accumulate EC events when they are
in sleep states which leads to EC buffer overflows that prevent new
events from being signaled after system resume or reboot. This has
been affecting many users for quite a while and may be addressed by
clearing the EC buffer during system resume and system startup on
those machines. From Kieran Clancy.
- If the ACPI sleep control and status registers are not present (which
happens if the Hardware Reduced ACPI mode bit is set in the ACPI
tables, but also may result from BIOS bugs), we should not try to use
ACPI to power off the system and ACPI S5 should not be listed as
supported. Fix from Aubrey Li.
- There's a race condition in cpufreq_get() that leads to a kernel
crash if that function is called at a wrong time. Fix from Aaron
Plattner.
- cpufreq policy objects have to be initialized entirely before they
are first accessed by their users which isn't the case currently and
that potentially leads to various kinds of breakage that is difficult
to debug. Fix from Viresh Kumar.

It's an enum, not a #define, you can't use it in asm files.
Introduced in commit 5fa10196bdb5 ("x86: Ignore NMIs that come in during
early boot"), and sadly I didn't compile-test things like I should have
before pushing out.
My weak excuse is that the x86 tree generally doesn't introduce stupid
things like this (and the ARM pull afterwards doesn't cause me to do a
compile-test either, since I don't cross-compile).

Pull tracing fix from Steven Rostedt:
"In the past, I've had lots of reports about trace events not working.
Developers would say they put a trace_printk() before and after the
trace event but when they enable it (and the trace event said it was
enabled) they would see the trace_printks but not the trace event.
I was not able to reproduce this, but that's because I wasn't looking
at the right location. Recently, another bug came up that showed the
issue.
If your kernel supports signed modules but allows for non-signed
modules to be loaded, then when one is, the kernel will silently set
the MODULE_FORCED taint on the module. Although, this taint happens
without the need for insmod --force or anything of the kind, it labels
the module with that taint anyway.
If this tainted module has tracepoints, the tracepoints will be
ignored because of the MODULE_FORCED taint. But no error message will
be displayed. Worse yet, the event infrastructure will still be
created letting users enable the trace event represented by the
tracepoint, although that event will never actually be enabled. This
is because the tracepoint infrastructure allows for non-existing
tracepoints to be enabled for new modules to arrive and have their
tracepoints set.
Although there are several things wrong with the above, this change
only addresses the creation of the trace event files for tracepoints
that are not created when a module is loaded and is tainted. This
change will print an error message about the module being tainted and
not the trace events will not be created, and it does not create the
trace event infrastructure"

Don Zickus reports:
A customer generated an external NMI using their iLO to test kdump
worked. Unfortunately, the machine hung. Disabling the nmi_watchdog
made things work.
I speculated the external NMI fired, caused the machine to panic (as
expected) and the perf NMI from the watchdog came in and was latched.
My guess was this somehow caused the hang.
----
It appears that the latched NMI stays latched until the early page
table generation on 64 bits, which causes exceptions to happen which
end in IRET, which re-enable NMI. Therefore, ignore NMIs that come in
during early execution, until we have proper exception handling.

bswapsdi2.{o,S} to arch/arm/boot/compressed/Makefile, but didn't update
the .gitignore. Thus after a a build git status shows bswapsdi2.S as a

Due to a problem in the MFD Kconfig it was not possible to
compile the UCB battery driver for the Collie SA1100 system,
in turn making it impossible to compile in the battery driver.
(See patch "mfd: include all drivers in subsystem menu".)
After fixing the MFD Kconfig (separate patch) a compile error
appears in the Collie battery driver due to the <mach/collie.h>
implicitly requiring <mach/hardware.h> through <linux/gpio.h>
via <mach/gpio.h> prior to commit
40ca061b "ARM: 7841/1: sa1100: remove complex GPIO interface".
Fix this up by including the required header into
<mach/collie.h>.

With noMMU, CONFIG_PAGE_OFFSET was not being set correctly. As there's
no MMU, PAGE_OFFSET should be equal to PHYS_OFFSET in all cases. This
commit makes that explicit.
Since we do this, we don't need to mess around in asm/memory.h with
ifdefs to sort this out, so let's get rid of that, and there's no point
offering the "Memory split" option for noMMU as that's meaningless
there.

Chris suggested to split things up a bit into the different parts of
the driver and also sort it all correctly, with the hope that we're
trying to organize things a bit better eventually. It should also
help newcomers to orient themselves a bit better.
v2:
- Move intel_pm.c to the core - to make things perfect we should split
out the modeset related pm features (psr/fbc) into a separate file.
Maybe something Rodrigo can do once the PSR patches have settled.
- Split the modesetting sections into core and encoders/outputs.
intel_ddi.c is a bit funky since it has core hsw+ support and ddi
output support. Whatever.
v3: Failed to git add ...
v4: Really go ocd, i.e. spelling fix in a comment from Jani.

The command parser scans batch buffers submitted via execbuffer ioctls before
the driver submits them to hardware. At a high level, it looks for several
things:
1) Commands which are explicitly defined as privileged or which should only be
used by the kernel driver. The parser generally rejects such commands, with
the provision that it may allow some from the drm master process.
2) Commands which access registers. To support correct/enhanced userspace
functionality, particularly certain OpenGL extensions, the parser provides a
whitelist of registers which userspace may safely access (for both normal and
drm master processes).
3) Commands which access privileged memory (i.e. GGTT, HWS page, etc). The
parser always rejects such commands.
See the overview comment in the source for more details.
This patch only implements the logic. Subsequent patches will build the tables
that drive the parser.

Make sure the line_time_us isn't zero in the gmch watermarks code as
that would cause a div by zero. This can be triggered by specifying
a very fast pixel clock for the mode.
At some point we should probably just switch over to using the same
math we use on PCH platforms which avoids such intermediate rounded
results.
Also we should verify the user provided mode much more rigorously.
At the moment we accept pretty much anything.
Note that "very fast mode" here means above 74.25 GHz.

Based on an early draft from Jesse.
Add support for powering on/off the dynamic power wells on VLV by
registering its display and dpio dynamic power wells with the power
domain framework.
For now power on all PHY TX lanes regardless of the actual lane
configuration. Later this can be optimized when the PHY side setup
enables only the required lanes. Atm, it enables all lanes in all
cases.
v2:
- undef function local COND macro after its last use (Ville)
- Take dev_priv->irq_lock around the whole sequence of
intel_set_cpu_fifo_underrun_reporting_nolock() and
valleyview_disable_display_irqs(). They are short and releasing
the lock in between only makes proving correctness more difficult.
