Expose raw packet capabilities in the core layer to enable a device
to report it.
Two existing capabilities, scatter FCS and IP CSUM were added to this
field for a better user experience by exposing the raw packet caps
from one location.
This field will serve also for future capabilities for raw packet QP.
A new capability was introduced - cvlan stripping, which is the
device's ability to remove cvlan tag from an incoming packet and
report it in the matching work completion.

Counters weren't updated due to Receive WQs' traffic since the
counter-id was not associated with the RQ.
Added support for associating the q-counter-id with the Receive WQ.
The attachment is done only when changing WQ's state from RESET to
READY in modify-WQ command.
FW support is required for the above, without this support
Receive WQ counters will not count.

The problem is that when the kernel tries to truncate an inode in
ext4_truncate(), it tries to clear any on-disk data beyond i_size.
Without the encryption key, it can't do that, and so it triggers a
BUG.
E2fsck does *not* provide this service, and in practice most file
systems have their orphan list processed by e2fsck, so to avoid
crashing, this patch skips this step if we don't have access to the
encryption key (which is the case when processing the orphan list; in
all other cases, we will have the encryption key, or the kernel
wouldn't have allowed the file to be opened).
An open question is whether the fact that e2fsck isn't clearing the
bytes beyond i_size causing problems --- and if we've lived with it
not doing it for so long, can we drop this from the kernel replay of
the orphan list in all cases (not just when we don't have the key for
encrypted inodes).

Since function tables are a common target for attackers, it's best to keep
them in read-only memory. As such, this makes the CDROM device ops tables
const. This drops additionally n_minors, since it isn't used meaningfully,
and sets the only user of cdrom_dummy_generic_packet explicitly so the
variables can all be const.
Inspired by similar changes in grsecurity/PaX.

The prox/range bits included in the Bluetooth reports from the Intuos Pro
were being ignored, leading to two issues. Firstly, the pen would never
announce a BTN_TOOL_PEN event with value 0, leaving userspace to believe
the pen was always active. Secondly, the driver would continue to send
events for data while the packet's "prox" bit was clear. This can lead
to sudden incorrect pointer jumps if the pen is slowly moved away from

Historically a lot of these existed because we did not have
a distinction between what was modular code and what was providing
support to modules via EXPORT_SYMBOL and friends. That changed
when we forked out support for the latter into the export.h file.
This means we should be able to reduce the usage of module.h
in code that is obj-y Makefile or bool Kconfig. In the case of
some code where it is modular, we can extend that to also include
files that are building basic support functionality but not related
to loading or registering the final module; such files also have
no need whatsoever for module.h
The advantage in removing such instances is that module.h itself
sources about 15 other headers; adding significantly to what we feed
cpp, and it can obscure what headers we are effectively using.
Since module.h might have been the implicit source for init.h
(for __init) and for export.h (for EXPORT_SYMBOL) we consider each
instance for the presence of either and replace/add as needed.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
Build coverage of all the mips defconfigs revealed the module.h
header was masking a couple of implicit include instances, so
we add the appropriate headers there.

Unify definitions for MIPS performance counter register fields in
mipsregs.h rather than duplicating them in perf_events and oprofile.
This will allow future patches to use them to expose performance
counters to KVM guests.

Disable stack checking on MIPS kernels. Some distribution toolchains
might pass the -fstack-check option to gcc. This results in a
store-doubleword instruction being emitted at the top of all
functions that checks the available stack space. E.g.,
a80000000001d740 <per_cpu_init>:
a80000000001d740: ffa0bfc0 sd zero,-16448(sp)
a80000000001d744: 2405ffc9 li a1,-55
a80000000001d748: 67bdffc0 daddiu sp,sp,-64
Generally, this is undesirable, and especially on the SGI IP27
platform, it will trigger a NULL pointer dereference in
'_raw_spin_lock_irq' during early init.

Add all the necessary platform code to initialize the dwc3
USB host controller. This code initializes the clocks and
performs a reset on the USB core and PHYs. The driver code
in 'drivers/usb/dwc3' is where the real driver lives.

Adding dedicated flag for AUTO_BKOPS in card->ext_csd structure.
Read AUTO_BKOPS bit value from the device EXT_CSD and set to the
card->ext_csd structure.
In mmc_decode_ext_csd() add a print message in case the AUTO_BKOPS
is enabled

Add support for HS400 mode.
The driver still misses support for tuning, therefore
highspeed modes like HS400 might not work under all
circumstances yet.

The remove callback is called only if probe finished successfully.
