commit 2b8bd423614c595540eaadcfbc702afe8e155e50 upstream.
Currently io_ticks is approximated by adding one at each start and end of
requests if jiffies counter has changed. This works perfectly for requests
shorter than a jiffy or if one of requests starts/ends at each jiffy.If disk executes just one request at a time and they are longer than two
jiffies then only first and last jiffies will be accounted.Fix is simple: at the end of request add up into io_ticks jiffies passed
since last update rather than just one jiffy.Example: common HDD executes random read 4k requests around 12ms.

[ Upstream commit ac67b07e268d46eba675a60c37051bb3e59fd201 ]
Currently, the aspeed-sgpio driver exposes up to 80 GPIO lines,
corresponding to the 80 status bits available in hardware. Each of these
lines can be configured as either an input or an output.However, each of these GPIOs is actually an input *and* an output; we
actually have 80 inputs plus 80 outputs.This change expands the maximum number of GPIOs to 160; the lower half
of this range are the input-only GPIOs, the upper half are the outputs.
We fix the GPIO directions to correspond to this mapping.This also fixes a bug when setting GPIOs - we were reading from the
input register, making it impossible to set more than one output GPIO.Signed-off-by: Jeremy Kerr

commit a0d1c951ef08ed24f35129267e3595d86f57f5d3 upstream.
As Documentation/kbuild/llvm.rst implies, building the kernel with a
full set of LLVM tools gets very verbose and unwieldy.Provide a single switch LLVM=1 to use Clang and LLVM tools instead
of GCC and Binutils. You can pass it from the command line or as an
environment variable.Please note LLVM=1 does not turn on the integrated assembler. You need
to pass LLVM_IAS=1 to use it. When the upstream kernel is ready for the
integrated assembler, I think we can make it default.We discussed what we need, and we agreed to go with a simple boolean
flag that switches both target and host tools:https://lkml.org/lkml/2020/3/28/494
https://lkml.org/lkml/2020/4/3/43Some items discussed, but not adopted:
- LLVM_DIR
When multiple versions of LLVM are installed, I just thought supporting
LLVM_DIR=/path/to/my/llvm/bin/ might be useful.CC = $(LLVM_DIR)clang
LD = $(LLVM_DIR)ld.lld
...However, we can handle this by modifying PATH. So, we decided to not do
this.- LLVM_SUFFIX
Some distributions (e.g. Debian) package specific versions of LLVM with
naming conventions that use the version as a suffix.CC = clang$(LLVM_SUFFIX)
LD = ld.lld(LLVM_SUFFIX)
...will allow a user to pass LLVM_SUFFIX=-11 to use clang-11 etc.,
but the suffixed versions in /usr/bin/ are symlinks to binaries in
/usr/lib/llvm-#/bin/, so this can also be handled by PATH.Signed-off-by: Masahiro Yamada

The problem the patch is trying to address is the fact that 'struct
kvm_hyperv_exit' has different layout on when compiling in 32 and 64 bit
modes.In 64-bit mode the default alignment boundary is 64 bits thus
forcing extra gaps after 'type' and 'msr' but in 32-bit mode the
boundary is at 32 bits thus no extra gaps.This is an issue as even when the kernel is 64 bit, the userspace using
the interface can be both 32 and 64 bit but the same 32 bit userspace has
to work with 32 bit kernel.The issue is fixed by forcing the 64 bit layout, this leads to ABI
change for 32 bit builds and while we are obviously breaking '32 bit
userspace with 32 bit kernel' case, we're fixing the '32 bit userspace
with 64 bit kernel' one.As the interface has no (known) users and 32 bit KVM is rather baroque
nowadays, this seems like a reasonable decision.Reviewed-by: Vitaly Kuznetsov

commit b5265c813ce4efbfa2e46fd27cdf9a7f44a35d2e upstream.
In some rare cases, for input data over 32 KB, lzo-rle could encode two
different inputs to the same compressed representation, so that
decompression is then ambiguous (i.e. data may be corrupted - although
zram is not affected because it operates over 4 KB pages).This modifies the compressor without changing the decompressor or the
bitstream format, such that:- there is no change to how data produced by the old compressor is
decompressed- an old decompressor will correctly decode data from the updated
compressor- performance and compression ratio are not affected
- we avoid introducing a new bitstream format
In testing over 12.8M real-world files totalling 903 GB, three files
were affected by this bug. I also constructed 37M semi-random 64 KB
files totalling 2.27 TB, and saw no affected files. Finally I tested
over files constructed to contain each of the ~1024 possible bad input
sequences; for all of these cases, updated lzo-rle worked correctly.There is no significant impact to performance or compression ratio.

SRBDS is an MDS-like speculative side channel that can leak bits from the
random number generator (RNG) across cores and threads. New microcode
serializes the processor access during the execution of RDRAND and
RDSEED. This ensures that the shared buffer is overwritten before it is
released for reuse.While it is present on all affected CPU models, the microcode mitigation
is not needed on models that enumerate ARCH_CAPABILITIES[MDS_NO] in the
cases where TSX is not supported or has been disabled with TSX_CTRL.The mitigation is activated by default on affected processors and it
increases latency for RDRAND and RDSEED instructions. Among other
effects this will reduce throughput from /dev/urandom.* Enable administrator to configure the mitigation off when desired using
either mitigations=off or srbds=off.* Export vulnerability status via sysfs
* Rename file-scoped macros to apply for non-whitelist table initializations.

…t for high speed devices")
commit 3155f4f40811c5d7e3c686215051acf504e05565 upstream.
Commit bd0e6c9614b9 ("usb: hub: try old enumeration scheme first for
high speed devices") changed the way the hub driver enumerates
high-speed devices. Instead of using the "new" enumeration scheme
first and switching to the "old" scheme if that doesn't work, we start
with the "old" scheme. In theory this is better because the "old"
scheme is slightly faster -- it involves resetting the device only
once instead of twice.However, for a long time Windows used only the "new" scheme. Zeng Tao
said that Windows 8 and later use the "old" scheme for high-speed
devices, but apparently there are some devices that don't like it.
William Bader reports that the Ricoh webcam built into his Sony Vaio
laptop not only doesn't enumerate under the "old" scheme, it gets hung
up so badly that it won't then enumerate under the "new" scheme! Only
a cold reset will fix it.Therefore we will revert the commit and go back to trying the "new"
scheme first for high-speed devices.Reported-and-tested-by: William Bader <williambader@hotmail.com>

is not relevant in this case, because the kernel will attempt to probe
the device as soon as a driver is loaded and if the generic designware
PCIe driver is loaded first, then this driver will be probed first.
Therefore, to fix this problem, remove the "snps,dw-pcie" string from
the compatible string as we never want this driver to be probe on

The V2X MU requires that the the sender changes the byte indication
the type of the message in its header. The value required changes
for each MU.This patch adds the documentation of this functionality adding
explanations for fsl,cmd_tag and fsl,rsp_tag.Signed-off-by: Stéphane Dion

commit f36938aa7440f46a0a365f1cfde5f5985af2bef3 upstream.
patch_realtek.c has historically failed to properly configure the PC
Beep Hidden Register for the ALC256 codec (among others). Depending on
your kernel version, symptoms of this misconfiguration can range from
chassis noise, picked up by a poorly-shielded PCBEEP trace, getting
amplified and played on your internal speaker and/or headphones to loud
feedback, which responds to the "Headphone Mic Boost" ALSA control,
getting played through your headphones. For details of the problem, see
the patch in this series titled "ALSA: hda/realtek - Set principled PC
Beep configuration for ALC256", which fixes the configuration.These symptoms have been most noticed on the Dell XPS 13 9350 and 9360,
popular laptops that use the ALC256. As a result, several model-specific
fixups have been introduced to try and fix the problem, the most
egregious of which locks the "Headphone Mic Boost" control as a hack to
minimize noise from a feedback loop that shouldn't have been there in
the first place.Now that the underlying issue has been fixed, remove all these fixups.
Remaining fixups needed by the XPS 13 are all picked up by existing pin
quirks.This change should, for the XPS 13 9350/9360
- Significantly increase volume and audio quality on headphones
- Eliminate headphone popping on suspend/resume
- Allow "Headphone Mic Boost" to be set again, making the headphone
jack fully usable as a microphone jack too.Fixes: 8c69729b4439 ("ALSA: hda - Fix headphone noise after Dell XPS 13 resume back from S3")
