Commit 79e539453b34e35f39299a899d263b0a1f1670bd introduced a
regression where you cannot use sysrq 'g' to enter kgdb. The solution
is to move the intel fb sysrq over to V for video instead of G for
graphics. The SMP VOYAGER code to register for the sysrq-v is not
anywhere to be found in the mainline kernel, so the comments in the
code were cleaned up as well.
This patch also cleans up the sysrq definitions for kgdb to make it
generic for the kernel debugger, such that the sysrq 'g' can be used
in the future to enter a gdbstub or another kernel debugger.

The receive interrupt routine checks the wrong register if the
receive fifo is empty. Further an explicit interrupt acknowledge
write is introduced. In some circumstances another interrupt was
issued.

IB/mlx4: Don't overwrite fast registration page list when posting work request

The low-level mlx4 driver modified the page-list addresses for fast
register work requests post send to big-endian, and set a "present"
bit. This caused problems later when the consumer attempted to unmap
the pages using the page-list (using the list addresses which were
assumed to be still in CPU-endian order). Fix the mlx4 driver to
allocate two buffers and use a private buffer for the hardware-format
bus addresses.
This patch fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1571>,

When the SQ is flushed, mark the flushed entries as not signaled so
the poll logic doesn't re-insert the CQ entry thinking its an out of
order completion.
The bug can cause the NFS/RDMA server to crash due to processing the
same completed work request twice.

This patch (as1240) adds the NOGET quirk for three devices from CH
Products: the Pro pedals, the Combatstick joystick, and the Flight-Sim
yoke. Without these quirks, the devices haven't worked for many
kernel releases. Sometimes replugging them after boot-up would get
them to work and sometimes they wouldn't work at all.

ioatdma 0000:00:08.0: DMA-API: device driver frees DMA memory with
wrong function [device address=0x000000007f76f800] [size=2000 bytes]
[map
ped as single] [unmapped as page]
The ioatdma driver was unmapping all regions
(either allocated as page or single) using unmap_page.
This patch lets dma driver recognize if unmap_single or unmap_page should be used.
It introduces two new dma control flags:
DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE.
They should be set to indicate dma driver to do dma-unmapping as single
(first one for the source, tha latter for the destination).
If respective flag is not set, the driver assumes dma-unmapping as page.

disable_irq() should wait for all running handlers to complete
before returning. As such, if it's used to disable an interrupt
from that interrupt's handler it will deadlock. This replaces
the dangerous instances with the _nosync() variant which doesn't
have this problem.
Note the 2 handlers in question are only used #ifdef DEBUG so
I imagine these code paths don't get hit often.

Fix a bug in viafb on x86_64 builds (e.g. for VIA Nano CPU).
You cannot make the assumption that sizeof(unsigned int) ==
sizeof(unsigned long), so the parsing of the default mode (640x480) fails,
leading to a division by zero during insmod of the driver.

When userspace sets effect->u.rumble.strong_magnitude to 0x8001 or
larger, ml_combine_effects() would always return strong_magnitude
0xffff.
Problem is that 'gain' is passed in as signed integer. Multiplying
magnitude (__u16) with gain (int) causes magnitude read as signed and
results negative value (with magnitude > 0x8000). This signed integer
is then divided and value, still negative, converted to 32bit unsigned
integer. Finally checking combine overflow min(new+old, 0xffff) gives
out 0xffff.
Fix is to simply change 'gain' to unsigned int.

See Errata documentation. The recommended workaround is to use PIO4 instead
which will we automatically do by flagging this mode not available.

Error timestamps are in jiffies which doesn't run while suspended and
PHY events during resume isn't too uncommon. When the two are
combined, it can lead to unnecessary speed downs if the machine is
suspended and resumed repeatedly. Clear error history on resume.

The original driver doesn't use 66 MHz clock for UDMA33.
[ The alternative solution would be to adjust UDMA33 timings
for 66 MHz clock but I think that it is safer to stick with
old & tested behavior for now. ]

New device attach path in ata_eh_revalidate_and_attach() is divided
into two separate loops because ATA requires IDENTIFY to be issued to
slave first while the user expects to see device probe messages from
the master device. new_mask is used to track which devices are the
new ones between the first loop and the second.
This usually works well but if an error occurs during configuration
stage, ata_dev_revalidate_and_attach() returns with error code and
forgets new_mask. On the retry run, dev->class is set and new_mask
for the device is clear, so the device just gets revalidated and thus
ends up skipping post-configuration procedure including scheduling of
SCSI_HOTPLUG for the device. When this occurs, ATA part of probing
works fine but SCSI probing usually doesn't happen and makes the
device unreachable.
The behavior has been around for a very long time but it has been
uncovered with the recent addition of 1_5_GBPS horkage which uses
-EAGAIN return value from ata_dev_configure() to restart the probing
sequence after forcing cable speed.
This can be fixed by making sure dev->class is permanently set only
after all configurations are successfully complete. Fix it.

PAGE_MASK is 0xFFFFF000 on i386 -- even with PAE.
So it's not sufficient to ensure that you use phys_addr_t or uint64_t
everywhere you handle physical addresses -- you also have to avoid using
the construct 'addr & PAGE_MASK', because that will strip the high 32
bits of the address.
This patch avoids that problem by using PHYSICAL_PAGE_MASK instead of
PAGE_MASK where appropriate. It leaves '& PAGE_MASK' in a few instances
that don't matter -- where it's being used on the virtual bus addresses
we're dishing out, which are 32-bit anyway.
Since PHYSICAL_PAGE_MASK is not present on other architectures, we have
to define it (to PAGE_MASK) if it's not already defined.
Maybe it would be better just to fix PAGE_MASK for i386/PAE?

Hey, I have an Edimax wireless USB adapter that uses the rt2870 chipset.
lsusb shows it as follows:
Bus 001 Device 002: ID 7392:7717
When I added that ID to rt2870.h, the device came up and worked as
expected.
