Per dwc3 2.50a spec, the is_devspec bit is used to distinguish the
Device Endpoint-Specific Event or Device-Specific Event (DEVT). If the
bit is 1, the event is represented Device-Specific Event, then use
[7:1] bits as Device Specific Event to marked the type. It has 7 bits,
and we can see the reserved8_31 variable name which means from 8 to 31
bits marked reserved, actually there are 24 bits not 25 bits between
that. And 1 + 7 + 24 = 32, the event size is 4 byes.
So in dwc3_event_type, the bit mask should be:
is_devspec [0] 1 bit
type [7:1] 7 bits
reserved8_31 [31:8] 24 bits
This patch should be backported to kernels as old as 3.2, that contain
the commit 72246da40f3719af3bfd104a2365b32537c27d83 "usb: Introduce
DesignWare USB3 DRD Driver".

This avoids a build error in at91sam9261_9g10_defconfig:

Making the call to at91udc_of_init conditinal also reduces

In case we fail our ->udc_start() callback, we
should be ready to accept another modprobe following
the failed one.
We had forgotten to clear dwc->gadget_driver back
to NULL and, because of that, we were preventing
gadget driver modprobe from being retried.

commit 681f130f39e10 ("netfilter: xt_socket: add XT_SOCKET_NOWILDCARD
flag") added a potential NULL dereference if an old iptables package
uses v0 of the match.
Fix this by removing the test on @info in fast path.
IPv6 can remove the test as well, as it uses v1 or v2.

nf_ct_expect_alloc leaves unset the expectation NAT fields. However,
ctnetlink_exp_dump_expect expects them to be zeroed in case they are
not used, which may not be the case. This results in dumping the NAT
tuple of the expectation when it should not.
Fix it by zeroing the NAT fields of the expectation.

On systems with no package MSR support this caused crash as there
is a bug in the logic to check presence of DTHERM and PTS feature
together. Added a change so that when there is no PTS support, module
doesn't get loaded. Even if some CPU comes online with the PTS
feature disabled, and other CPUs has this support, this patch
will still prevent such MSR accesses.

Some callers of ext4_es_remove_extent() and ext4_es_insert_extent()
may not be completely robust against ENOMEM failures (or the
consequences of reflecting ENOMEM back up to userspace may lead to
xfstest or user application failure).
To mitigate against this, when trying to insert an entry in the extent
status tree, try to shrink the inode's extent status tree before
returning ENOMEM. If there are entries which don't record information
about extents under delayed allocations, freeing one of them is
preferable to returning ENOMEM.

In ext4_ext_map_blocks(), if we have successfully allocated the data
blocks, but then run into trouble inserting the extent into the extent
tree, most likely due to an ENOSPC condition, determine the arguments
to ext4_free_blocks() in a simpler way which is easier to prove to be
correct.

Previously ext4_ext_truncate() was ignoring potential error returns
from ext4_es_remove_extent() and ext4_ext_remove_space(). This can
lead to the on-diks extent tree and the extent status tree cache
getting out of sync, which is particuarlly bad, and can lead to file
system corruption and potential data loss.

The fec/enet driver calculates MDC rate with the formula below.
ref_freq / ((MII_SPEED + 1) x 2)
The ref_freq here is the fec internal module clock, which is missing
from clk-vf610 clock driver right now. And clk-vf610 driver mistakenly
supplies RMII clock (50 MHz) as the source to fec. This results in the
situation that fec driver gets ref_freq as 50 MHz, while physically it
runs at 66 MHz (fec module clock physically sources from ipg which runs
at 66 MHz). That's why software expects MDC runs at 2.5 MHz, while the
measurement tells it runs at 3.3 MHz. And this causes the PHY KSZ8041
keeps swithing between Full and Half mode as below.
libphy: 400d0000.etherne:00 - Link is Up - 100/Full
libphy: 400d0000.etherne:00 - Link is Up - 100/Half
libphy: 400d0000.etherne:00 - Link is Up - 100/Full
libphy: 400d0000.etherne:00 - Link is Up - 100/Half
libphy: 400d0000.etherne:00 - Link is Up - 100/Full
libphy: 400d0000.etherne:00 - Link is Up - 100/Half

The current default pad configuration for UART RX and TX pads sets a 360k
pull-down and writes 1 to a reserved bit (1 << 0). It doesn't seem right to
me that in idle state, the UART has to keep the signal high against a
pull-down resistor.
This patch instead sets a 100k pull-up, which incidentally corresponds to the
register reset value for all but one (MX53_PAD_KEY_ROW0__UART4_RXD_MUX) pad,
and removes the write to the reserved bit.

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications. For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.
After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out. Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.
This removes all the drivers/block uses of the __cpuinit macros
from all C files.

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications. For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.
After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out. Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.
Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
are flagged as __cpuinit -- so if we remove the __cpuinit from
arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
content into no-ops as early as possible, since that will get rid
of these warnings. In any case, they are temporary and harmless.
This removes all the arch/hexagon uses of the __cpuinit macros from

Here, we remove all the MIPS __cpuinit from C code and __CPUINIT
from asm files. MIPS is interesting in this respect, because there
are also uasm users hiding behind their own renamed versions of the
__cpuinit macros.
