Currently, intel_pstate_update_perf_limits() first converts the
policy minimum and maximum limits into percentages of the maximum
turbo frequency (rounding up to an integer) and then converts these
percentages to fractions (by using fixed-point arithmetic to divide
them by 100).
That introduces a rounding error unnecessarily, because the fractions
can be obtained by carrying out fixed-point divisions directly on the
input numbers.
Rework the computations in intel_pstate_hwp_set() to use fractions
instead of percentages (and drop redundant local variables from
there) and modify intel_pstate_update_perf_limits() to compute the
fractions directly and percentages out of them.
While at it, introduce percent_ext_fp() for converting percentages
to fractions (with extended number of fraction bits) and use it in
the computations.

The rdtgroup_kn_unlock waits for the last user to release and put its

This race could be easily reproduced by running 2 instances
of following script:
mount -t resctrl resctrl /sys/fs/resctrl/
pushd /sys/fs/resctrl/
mkdir krava
echo "krava" > krava/schemata
rmdir krava
popd
umount /sys/fs/resctrl
It triggers the slub debug error message with following command
line config: slub_debug=,kernfs_node_cache.

Pavel Machek reported the following warning on x86-32:
WARNING: kernel stack frame pointer at f50cdf98 in swapper/2:0 has bad value (null)
The warning is caused by the unwinder not realizing that it reached the
end of the stack, due to an unusual prologue which gcc sometimes
generates for aligned stacks. The prologue is based on a gcc feature
called the Dynamic Realign Argument Pointer (DRAP). It's almost always
enabled for aligned stacks when -maccumulate-outgoing-args isn't set.
This issue is similar to the one fixed by the following commit:
8023e0e2a4 ("x86/unwind: Adjust last frame check for aligned function stacks")
... but that fix was specific to x86-64.
Make the fix more generic to cover x86-32 as well, and also ensure that
the return address referred to by the frame pointer is a copy of the
original return address.

The more significant portions:
Patch #1 would cause timeout when qedr utilizes the highest

Patch #4 fixes a leak of mapped addresses; When iommu is enabled,
offloaded storage protocols might eventually run out of resources

Before iterating over the the LL2 Rx ring, the ring's
spinlock is taken via spin_lock_irqsave().
The actual processing of the packet [including handling
by the protocol driver] is done without said lock,
so qed releases the spinlock and re-claims it afterwards.
Problem is that the final spin_lock_irqrestore() at the end
of the iteration uses the original flags saved from the
initial irqsave() instead of the flags from the most recent
irqsave(). So it's possible that the interrupt status would
be incorrect at the end of the processing.

The setup/remove_state/instance() functions in the hotplug core code are
serialized against concurrent CPU hotplug, but unfortunately not serialized
against themself.
As a consequence a concurrent invocation of these function results in
corruption of the callback machinery because two instances try to invoke
callbacks on remote cpus at the same time. This results in missing callback
invocations and initiator threads waiting forever on the completion.
The obvious solution to replace get_cpu_online() with cpu_hotplug_begin()
is not possible because at least one callsite calls into these functions
from a get_online_cpu() locked region.
Extend the protection scope of the cpuhp_state_mutex from solely protecting
the state arrays to cover the callback invocation machinery as well.

sdhci_arasan_get_timeout_clock() divides the frequency it has with (1 <<
(13 + divisor)).
However, the divisor is not some Arasan-specific value, but instead is
just the Data Timeout Counter Value from the SDHCI Timeout Control
Register.
Applying it here like this is wrong as the sdhci driver already takes
that value into account when calculating timeouts, and in fact it *sets*
that register value based on how long a timeout is wanted.
Additionally, sdhci core interprets the .get_timeout_clock callback
return value as if it were read from hardware registers, i.e. the unit
should be kHz or MHz depending on SDHCI_TIMEOUT_CLK_UNIT capability bit.
This bit is set at least on the tested Zynq-7000 SoC.
With the tested hardware (SDHCI_TIMEOUT_CLK_UNIT set) this results in
too high a timeout clock rate being reported, causing the core to use
longer-than-needed timeouts. Additionally, on a partitioned MMC
(therefore having erase_group_def bit set) mmc_calc_max_discard()
disables discard support as it looks like controller does not support
the long timeouts needed for that.
Do not apply the extra divisor and return the timeout clock in the
expected unit.
Tested with a Zynq-7000 SoC and a partitioned Toshiba THGBMAG5A1JBAWR
eMMC card.

Rockchip finally named the SOC as RV1108, so change it.
