Instead of using global variables we are going to use dynamically allocated
memory. It allows to append a support of more than one ethernet adapter which
might have different settings simultaniously.

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so some #ifdef blocks
depending on CONFIG_PM_RUNTIME may be dropped now.
Do that in drivers/i2c/busses/i2c-omap.c.

This patch checks if the process that opens the /dev/kfd device is 32-bit
process. If so, it returns -EPERM and prints a warning message in dmesg.
This is done to prevent 32-bit user processes from using amdkfd, and hence, HSA
features.
AMD's HSA userspace stack will also support only 64-bit processes on Linux.

A crash was observed while cfg80211 del_station handler is
called while stopping AP. This was happening because we were
deleting station list and Rx reorder table entries in del_sta
handler. While station entry is being deleted here, it may happen
that station deauth event from FW would also try to delete station
entry.
This patch fixes this crash by not deleting station entries in del_station
handler. Entry would be deleted while processing station deauth event; which
is triggered by del_station command to FW.

This patch resolves couple of issues in ixgbevf_probe/remove():
1. Fix a case where adapter->state is tested after free_netdev() this is
same as the patch for ixgbe from Daniel Borkmann <dborkman@redhat.com>:
commit b5b2ffc0574e1f27 ("ixgbe: fix use after free adapter->state test in ixgbe_remove/ixgbe_probe")
2. Move pci_set_drvdata() after all the error checks in ixgbevf_probe() and
then add a check in ixgbevf_probe() to avoid running the cleanup functions
twice in cases where probe failed.

The driver has logic to free up used data in case any of the checks in
ixgbe_probe() fail, however there is a similar set of cleanups that can
occur on driver unload in ixgbe_remove() which can cause the rmmod command
to crash.
This patch aims to fix the logic by moving pci_set_drvdata() after all error
checks and then adds a check in ixgbe_remove() to skip it altogether if
adapter comes up empty.

This patch extends the function pointer structure to include the new
X550 class MAC types. This creates a new file ixgbe_x550.c that contains
all of the new methods. Because of similarities to the X540 part in
some cases we just use it's methods where they can be used without any
modification. These exported functions are now defined in the new
ixgbe_x540.h file.

Currently the shared code checksum calculation function only
returns a u16 and cannot return an error code. Unfortunately
a variety of errors can happen that completely prevent the
calculation of a checksum. So, change the function return value
from a u16 to an s32 and return a negative value on error, or the
positive checksum value when there is no error.

The X550 hardware will use more bits in the mask, so change
the prototypes to match. This larger mask will require changes
in callers which use the higher bits. Likewise since X550 will
use different semaphore mask values and will use the lan_id

Accessing the CIAA/D register can block access to the PCI config space.
This patch removes the read/write operations to the CIAA/D registers
and makes use of standard kernel functions for accessing the PCI config
space.
In addition it moves ixgbevf_check_for_bad_vf() into the watchdog subtask
which reduces the frequency of the checks.

This change cleans up the tail writes for the ixgbe descriptor queues. The
current implementation had me confused as I wasn't sure if it was still
making use of the surprise remove logic or not.
It also adds the mmiowb which is needed on ia64, mips, and a couple other
architectures in order to synchronize the MMIO writes with the Tx queue
_xmit_lock spinlock.

This patch cleans up the page reuse code getting it into a state where all
the workarounds needed are in place as well as cleaning up a few minor
oversights such as using __free_pages instead of put_page to drop a locally
allocated page.
It also cleans up how we clear the descriptor status bits. Previously they
were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a
64 bit field and 64 bit writes can be a bit more expensive on on 32 bit
systems. Since we are no longer using the header split feature the upper
32 bits of the address no longer need to be cleared. As a result we can
just clear the status bits and leave the length and VLAN fields as-is which
should provide more information in debugging.

So apparently jiffies<->nsec<->ktime isn't accurate or something. At
elast if we timeout there's occasionally still a few hundred us left
(in a 2 second timeout).
Stuff I've tried and thrown out again:
- Sampling the before timestamp before jiffies. Doesn't improve test
path rate at all.
- Using jiffies. Way to inaccurate, which means way too much drift
with signals plus automatic ioctl restarting in userspace. In
hindsight we should have used an absolute timeout, but hey we need
something for v3 of the i915 gem wait interfaces ;-)
- Trying to figure out where accuracy gets lost. gl testcase really
don't care all that much about this (as long as isn't not massively
off), it's just that the testcase gets a bit upset if it receives an
EITME with timeout > 0.
So as long as we're in the ballbark it's good enough. So patch
everything up if we're at most one jiffies off. I get's me a solid
test again.
This regression is probably introduced in

So fix this up by reinstating our handrolled _timeout function. While
at it bother with handling MAX_JIFFIES.
v2: Convert to usecs (we don't care about the accuracy anyway) first
to avoid overflow issues Dave Gordon spotted.
v3: Drop the explicit MAX_JIFFY_OFFSET check, usecs_to_jiffies should
take care of that already. It might be a bit too enthusiastic about it
though.
v4: Chris has a much nicer color, so use his implementation.
This requires to export nsec_to_jiffies from time.c.
