People with old AMD chips are getting hung boots, because commit
bcb80e53877c ("x86, microcode, AMD: Add microcode revision to
/proc/cpuinfo") moved the microcode detection too early into
"early_init_amd()".
At that point we are *so* early in the booth that the exception tables
haven't even been set up yet, so the whole
rdmsr_safe(MSR_AMD64_PATCH_LEVEL, &c->microcode, &dummy);
doesn't actually work: if the rdmsr does a GP fault (due to non-existant
MSR register on older CPU's), we can't fix it up yet, and the boot fails.
Fix it by simply moving the code to a slightly later point in the boot
(init_amd() instead of early_init_amd()), since the kernel itself
doesn't even really care about the microcode patchlevel at this point
(or really ever: it's made available to user space in /proc/cpuinfo, and
updated if you do a microcode load).

The idea behind commit d91ee5863b71 ("cpuidle: replace xen access to x86
pm_idle and default_idle") was to have one call - disable_cpuidle()
which would make pm_idle not be molested by other code. It disallows
cpuidle_idle_call to be set to pm_idle (which is excellent).
But in the select_idle_routine() and idle_setup(), the pm_idle can still
be set to either: amd_e400_idle, mwait_idle or default_idle. This
depends on some CPU flags (MWAIT) and in AMD case on the type of CPU.
In case of mwait_idle we can hit some instances where the hypervisor
(Amazon EC2 specifically) sets the MWAIT and we get:
Brought up 2 CPUs
invalid opcode: 0000 [#1] SMP
Pid: 0, comm: swapper Not tainted 3.1.0-0.rc6.git0.3.fc16.x86_64 #1
RIP: e030:[<ffffffff81015d1d>] [<ffffffff81015d1d>] mwait_idle+0x6f/0xb4
...
Call Trace:
[<ffffffff8100e2ed>] cpu_idle+0xae/0xe8

RIP [<ffffffff81015d1d>] mwait_idle+0x6f/0xb4
RSP <ffff8801d28ddf10>
In the case of amd_e400_idle we don't get so spectacular crashes, but we
do end up making an MSR which is trapped in the hypervisor, and then
follow it up with a yield hypercall. Meaning we end up going to
hypervisor twice instead of just once.
The previous behavior before v3.0 was that pm_idle was set to
default_idle regardless of select_idle_routine/idle_setup.
We want to do that, but only for one specific case: Xen. This patch
does that.

This reverts commit df711fc9962b9491af2b92bd0d21ecbfefe4e5fa.
The commit added a reset-on-resume quirk because the NEC chipset stopped
responding to commands about 30 minutes after a system resume from
suspend. We thought it was a chipset issue, but it turns out that the
xHCI driver was zeroing out the link TRB after a successful context
restore during resume. The host controller would fall off the command
ring sometime later, causing it to not respond to new commands.
The link TRB issue has been fixed with commit
158886cd2cf4599e04f9b7e10cb767f5f39b14f1 "xHCI: fix bug in
xhci_clear_command_ring()", so revert the reset-on-resume quirk, as it's
not necessary.
Commit df711fc9962b9491af2b92bd0d21ecbfefe4e5fa was marked for stable
trees back to 2.6.37, but according to my mail, it has not made it into
Linus' tree or the stable trees yet.

When system enters suspend, xHCI driver clears command ring by writing zero
to all the TRBs. However, this also writes zero to the Link TRB, and the ring
is mangled. This may cause driver accesses wrong memory address and the
result is unpredicted.
When clear the command ring, keep the last Link TRB intact, only clear its
cycle bit. This should fix the "command ring full" issue reported by Oliver
Neukum.
This should be backported to stable kernels as old as 2.6.37, since the
commit 89821320 "xhci: Fix command ring replay after resume" is merged.

This error is caused by the follwing commit:
(16fcb63: arm/imx: remove mx31_setup_weimcs( ) from mx31.h)
,which removed '#include <linux/io.h>' from mx31.h.
fsl_mxc_udc.c includes <mach/hardware.h>, which in turns includes mx31.h, so
that's the reason fsl_mxc_udc.c built fine previously.
Instead of relying on the indirect inclusion of the linux/io.h header file,
include it directly in fsl_mxc_udc.c.

Several UDC drivers had a gadget driver's speed sanity check of the
form of:
driver->speed != USB_SPEED_HIGH
or:
driver->speed != USB_SPEED_HIGH && driver->speed != USB_SPEED_FULL
As more and more gadget drivers support USB SuperSpeed, driver->speed
may be set to USB_SPEED_SUPER and UDC driver should handle such gadget
correctly. The above checks however fail to recognise USB_SPEED_SUPER
as a valid speed.
This commit changes the two checks to:
driver->speed < USB_SPEED_HIGH
or:
driver->speed < USB_SPEED_FULL
respectively.

Currently the driver tries to save context in the suspend path, but
will cause an abort if the device is already runtime suspended. This
happens, for example, if MUSB loaded/compiled-in, in host mode, but no
USB devices are attached. MUSB will be runtime suspended, but then
attempting a system suspend will crash due to the context save
being attempted while the device is disabled.
On OMAP, as of v3.1, the driver's ->runtime_suspend() callback will be
called late in the suspend path (by the PM domain layer) if the driver
is not already runtime suspended, ensuring a full shutdown.
Therefore, the context save is not needed in the ->suspend() method
since it will be called in the ->runtime_suspend() method anyways
(similarily for resume.)
NOTE: this leaves the suspend/resume methods basically empty (with
some FIXMEs and comments, but I'll leave it to the maintainers
to decide whether to remove them.

There is a potential integer overflow in do_insnlist_ioctl() if
userspace passes in a large insnlist.n_insns. The call to kmalloc()
would allocate a small buffer, leading to a memory corruption.

and Haogang Chen <haogangchen@gmail.com>. The patch was suggested by
Ian Abbott <abbotti@mev.co.uk> and Lars-Peter Clausen <lars@metafoo.de>.

There is an integer overflow here that could cause memory corruption
on 32 bit systems.
insnlist.n_insns could be a very high value size calculation for
kmalloc() could overflow resulting in a smaller "insns" than
expected. In the for (i = 0; i < insnlist.n_insns; i++) {... loop
we would read past the end of the buffer, possibly corrupting memory
as well.

In comedi_fops, mmap_count is decremented at comedi_vm_ops->close but
it is not incremented at comedi_vm_ops->open. This may result in a negative
counter. The patch introduces the open method to keep the counter
consistent.
The bug was triggerd by this sample code:
mmap(0, ...., comedi_fd);

Interrupts must be disabled prior to calling usb_hcd_unlink_urb_from_ep.
If interrupts are not disabled, it can potentially lead to a deadlock.
The deadlock is readily reproduceable on a slower (ARM based) device
such as the TI Pandaboard.

xfs: fix attr2 vs large data fork assert

With Dmitry fsstress updates I've seen very reproducible crashes in
xfs_attr_shortform_remove because xfs_attr_shortform_bytesfit claims that
the attributes would not fit inline into the inode after removing an
attribute. It turns out that we were operating on an inode with lots
of delalloc extents, and thus an if_bytes values for the data fork that
is larger than biggest possible on-disk storage for it which utterly
confuses the code near the end of xfs_attr_shortform_bytesfit.
Fix this by always allowing the current attribute fork, like we already
do for the attr1 format, given that delalloc conversion will take care
for moving either the data or attribute area out of line if it doesn't
fit at that point - or making the point moot by merging extents at this
point.
Also document the function better, and clean up some loose bits.

If we are doing synchronous inode reclaim we block the VM from making
progress in memory reclaim. So if we encouter a flush locked inode
promote it in the delwri list and wake up xfsbufd to write it out now.
Without this we can get hangs of up to 30 seconds during workloads hitting
synchronous inode reclaim.
The scheme is copied from what we do for dquot reclaims.

Genera Touch told us that 0001 is their single point device
and 0003 is the multitouch one. Apparently, we made the tests
someone having a prototype, and not the final product.
They said it should be safe to do the switch.
This partially reverts 5572da0 ("HID: hid-mulitouch: add support

There are two issues in vmw_kms_update_layout_ioctl(). First, the
for loop forgets to index rects and only checks the first element.
Second, there is a potential integer overflow if userspace passes
in a large arg->num_outputs. The call to kzalloc() would allocate
a small buffer, leading to out-of-bounds read.

Disabling the CRTC by setting its framebuffer to NULL, as used by
drm_framebuffer_cleanup(), was failing to pass the current framebuffer
to the crtc_func->disable callback. This is because of the dance within
drm_crtc_helper_set_config to pass the new_fb (NULL in this case) to the
drm_crtc_helper_set_mode with the currently attached fb as a parameter.
drm_crtc_helper_set_mode treats this as a no-op and the encoder is still
enabled. And so the current fb is forgotten before the call to
drm_helper_disable_unused_functions.
This patch treats disabling the CRTC as a simple special case rather
than adding further complexity into the configuration logic.
This fixes a pin-leak of the fb bo on Xserver close.

I am under the impression that it only makes sense to call the ATIF
method if the graphics device has an ACPI handle attached. So we could
skip the call altogether if there is no such handle.

Use the proper macro to issue the debugging message in
radeon_atif_call(). Otherwise we spam the log of many systems with a
message which looks like an error message of unknown origin, and could
thus confuse the user. Commit dc77de12dde95c8da39e4c417eb70c7d445cf84b
was a first step in this direction, but was not sufficient IMHO.
