clk: tegra: remove USB from clk init table
The USB clocks are just clock gates, so no need to set a specific clock.
In fact trying to set a specific clock is just a NOP if the requested
clockrate is the same as those of the parent (clk_m) or will trigger a
WARN_ON() if rates don't match up.
As we are not setting a specific rate, nor activating the clocks at
init, there is no point in keeping the the usb entries in the clock init
table.

x86: Fix bit corruption at CPU resume time
In commit
78d77df71510 ("x86-64, init: Do not set NX bits on non-NX
capable hardware") we added the early_pmd_flags that gets the NX bit set
when a CPU supports NX. However, the new variable was marked __initdata,
because the main _use_ of this is in an __init routine.
However, the bit setting happens from secondary_startup_64(), which is
called not only at bootup, but on every secondary CPU start. Including
resuming from STR and at CPU hotplug time. So the value cannot be
__initdata.

Pull devm usage cleanup from Wolfram Sang:
"Lately, I have been experimenting how to improve the devm interface to
make writing device drivers easier and less error prone while also
getting rid of its subtle issues. I think it has more potential but
still needs work and definately conistency, especiall in its usage.
The first thing I come up with is a low hanging fruit regarding
devm_ioremap_resouce(). This function already checks if the passed
resource is valid and gives an error message if not. So, we can
remove similar checks from the drivers and get rid of a bit of code
and a number of inconsistent error strings.
This series only removes the unneeded check iff devm_ioremap_resource
follows platform_get_resource directly. The previous version tried to
shuffle code if needed, too, what lead to an embarrasing bug. It
turned out to me that shuffling code for all cases found will make the
automated script too complex, so I am unsure if an automated cleanup
is the proper tool for this case. Removing the easy stuff seems
worthwhile to me, though.
Despite various architectures and platform dependencies, I managed to
compile test 45 out of 57 modified files locally using heuristics and
defconfigs."

Btrfs: use a btrfs bioset instead of abusing bio internals
Btrfs has been pointer tagging bi_private and using bi_bdev
to store the stripe index and mirror number of failed IOs.
As bios bubble back up through the call chain, we use these
to decide if and how to retry our IOs. They are also used
to count IO failures on a per device basis.
Recently a bio tracepoint was added lead to crashes because
we were abusing bi_bdev.
This commit adds a btrfs bioset, and creates explicit fields
for the mirror number and stripe index. The plan is to
extend this structure for all of the fields currently in
struct btrfs_bio, which will mean one less kmalloc in
our IO path.

btrfs: do away with non-whole_page extent I/O
end_bio_extent_readpage computes whole_page based on bv_offset and
bv_len, without taking into account that blk_update_request may modify
them when some of the blocks to be read into a page produce a read
error. This would cause the read to unlock only part of the file
range associated with the page, which would in turn leave the entire
page locked, which would not only keep the process blocked instead of
returning -EIO to it, but also prevent any further access to the file.
It turns out that btrfs always issues whole-page reads and writes.
The special handling of non-whole_page appears to be a mistake or a
left-over from a time when this wasn't the case. Indeed,
end_bio_extent_writepage distinguished between whole_page and
non-whole_page writes but behaved identically in both cases!
I've replaced the whole_page computations with warnings, just to be
sure that we're not issuing partial page reads or writes. The
warnings should probably just go away some time.

MIPS: Extract schedule_mfi info from __schedule
schedule_mfi is supposed to be extracted from schedule(), and

But, after optimization, schedule() is reduced to a sibling

One solution is to compile schedule() with -fno-omit-frame-pointer

degradation.
Another solution is to extract info from the real scheduler,
__schedule, and this is the approache adopted here.
This patch reads the __schedule address by either following
the 'j' call in schedule if KALLSYMS is disabled or by using
kallsyms_lookup_name to lookup __schedule if KALLSYMS is

Given a function, get_frame_info() analyzes its instructions
to figure out frame size and return address. get_frame_info()
works as follows:
1. analyze up to 128 instructions if the function size is unknown
2. search for 'addiu/daddiu sp,sp,-immed' for frame size
3. search for 'sw ra,offset(sp)' for return address
4. end search when it sees jr/jal/jalr
This leads to an issue when the given function is a sibling

arm64: debug: fix mdscr.ss check when enabling debug exceptions
When we take an exception at EL1, we only want to enable debug
exceptions if we're not currently stepping, otherwise we can easily get
stuck in a loop stepping into interrupt handlers.
Unfortunately, the current code tests the wrong bit in the mdscr, so fix
that.

ALSA: usb-audio: proc: use found syncmaxsize to determine feedback format
freqshift is only set for the data endpoint and syncmaxsize is only set
for the sync endpoint. This results in a syncmaxsize of zero used in the
proc output feedback format calculation, which gives a feedback format
incorrectly shown as 8.16 for UAC2 devices.
As neither the data nor the sync endpoint gives all the relevant
content, output the two combined.
Also remove the sync_endpoint "packet size" which is always zero
and the sync_endpoint "momentary freq" which is constant.
Tested with UAC2 async and UAC1 adaptive, not tested with UAC1 async.

When UMS was deprecated it removed support for nomodeset commandline
we really want this in distro land so we can debug stuff, everyone
should fallback to vesa correctly.
v2: oops -1 isn't used anymore, restore original behaviour
-1 is default, so we can boot with nomodeset on the command line,
then use radeon.modeset=1 to override it for debugging later.

drm/qxl: fix ioport interactions for kernel submitted commands.
So qxl has ioports, but it really really really doesn't want you
to write to them twice, but if you write and get a signal before
the irq arrives to let you know its completed, you have to think
ahead and avoid writing another time.
However this works fine for update area where really multiple
writes aren't the end of the world, however with create primary
surface, you can't ever do multiple writes. So this stop internal
kernel writes from doing interruptible waits, because otherwise
we have no idea if this write is a new one or a continuation of
a previous one.
virtual hw sucks more than real hw.
This fixes lockups and VM crashes when resizing and starting/stopping
X.
