Despite never getting called from atomic context,
usb URB memory allocations use GFP_ATOMIC, which does not sleep
for allocation.
GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL,
which can sleep and improve the possibility of sucessful allocation.
This is found by a static analysis tool named DCNS written by myself.
And I also manually check it.

As the kernel doc "timers-howto.txt" reads,
short delay with msleep() can take much longer.
In a case of raspbery-pi platform where CONFIG_HZ_100 was set,
it actually affected the init of Friio devices
since it issues lots of i2c transactions with short delay.

Pull rdma fixes from Doug Ledford:
"This is our first pull request of the rc cycle. It's not that it's
been overly quiet, we were just waiting on a few things before sending
this off.
For instance, the 6 patch series from Intel for the hfi1 driver had
actually been pulled in on Tuesday for a Wednesday pull request, only
to have Jason notice something I missed, so we held off for some
testing, and then on Thursday had to respin the series because the
very first patch needed a minor fix (unnecessary cast is all).
There is a sizable hns patch series in here, as well as a reasonably
largish hfi1 patch series, then all of the lines of uapi updates are
just the change to the new official Linux-OpenIB SPDX tag (a bunch of
our files had what amounts to a BSD-2-Clause + MIT Warranty statement
as their license as a result of the initial code submission years ago,
and the SPDX folks decided it was unique enough to warrant a unique
tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4
and core/cache/cma updates to round out the bunch.
None of it was overly large by itself, but in the 2 1/2 weeks we've
been collecting patches, it has added up :-/.
As best I can tell, it's been through 0day (I got a notice about my
last for-next push, but not for my for-rc push, but Jason seems to
think that failure messages are prioritized and success messages not
so much). It's also been through linux-next. And yes, we did notice in
the context portion of the CMA query gid fix patch that there is a
dubious BUG_ON() in the code, and have plans to audit our BUG_ON usage
and remove it anywhere we can.

Since commit d677a4d601 ("Makefile: support flag
-fsanitizer-coverage=trace-cmp"), you miss to build the SANCOV
plugin under some circumstances.
CONFIG_KCOV=y
CONFIG_KCOV_ENABLE_COMPARISONS=y
Your compiler does not support -fsanitize-coverage=trace-pc
Your compiler does not support -fsanitize-coverage=trace-cmp
Under this condition, $(CFLAGS_KCOV) is not empty but contains a
space, so the following ifeq-conditional is false.
ifeq ($(CFLAGS_KCOV),)
Then, scripts/Makefile.gcc-plugins misses to add sancov_plugin.so to
gcc-plugin-y while the SANCOV plugin is necessary as an alternative
means.

I managed to send some modpost patches to old addresses of both
Masahiro and Michal, and omitted linux-kbuild from cc, because my
tried and trusted scripts/get_maintainer wrapper failed me. Add the
modpost directory to the MAINTAINERS entry, and while at it make the
Makefile glob match scripts/Makefile itself, and add one matching the
Kbuild.include file as well.

This reverts commit 22072e83eb as it is
broken.
Alan writes:
What you can't see just from reading the patch is that in both
cases (ehci->itd_pool and ehci->sitd_pool) there are two
allocation paths -- the two branches of an "if" statement -- and
only one of the paths calls dma_pool_[z]alloc. However, the
memset is needed for both paths, and so it can't be eliminated.
Given that it must be present, there's no advantage to calling
dma_pool_zalloc rather than dma_pool_alloc.

Right now it's possible to set dell laptop to compile in but this
causes dell-smbios to compile in which breaks if dcdbas is a module.
Dell laptop shouldn't select dell-smbios anymore, but depend on it.
