The parisc kernel doesn't work with CONFIG_MODVERSIONS since the commit
71810db27c1c853b335675bee335d893bc3d324b. It can't load modules with the
error: "module unix: Unknown relocation: 41".
The commit changes __kcrctab from 64-bit valus to 32-bit values. The
assembler generates R_PARISC_SECREL32 secrel relocation for them and the
module loader doesn't support this relocation.
This patch adds the R_PARISC_SECREL32 relocation to the module loader.

Pull SCSI fixes from James Bottomley:
"This is a rather large set of fixes. The bulk are for lpfc correcting
a lot of issues in the new NVME driver code which just went in in the
merge window.
The others are:
- fix a hang in the vmware paravirt driver caused by incorrect
handling of the new MSI vector allocation
- long standing bug in storvsc, which recent block changes turned
from being a harmless annoyance into a hang
- yet more fallout (in mpt3sas) from the changes to device blocking

Reviewing the result of what was just added for Kconfig, we made a poor
choice. It worked well for full kernel builds, but not so much for how
it would be deployed on a distro.
Here's the final result:
- lpfc will compile in NVME initiator and/or NVME target support based
on whether the kernel has the corresponding subsystem support.
Kconfig is not used to drive this specifically for lpfc.
- There is a module parameter, lpfc_enable_fc4_type, that indicates
whether the ports will do FCP-only or FCP & NVME (NVME-only not yet
possible due to dependency on fc transport). As FCP & NVME divvys up
exchange resources, and given NVME will not be often initially, the
default is changed to FCP only.

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
node. But it's calling kernfs_put on the node which calls the
rdtgroup_kn_unlock, which might not be the group's directory node, but
another group's file node.
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.
Call kernfs_put on the group's node to fix it.

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:
8023e0e2a48d ("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.

While working on the futex code, I stumbled over this potential
use-after-free scenario. Dmitry triggered it later with syzkaller.
pi_mutex is a pointer into pi_state, which we drop the reference on in
unqueue_me_pi(). So any access to that pointer after that is bad.
Since other sites already do rt_mutex_unlock() with hb->lock held, see
for example futex_lock_pi(), simply move the unlock before
unqueue_me_pi().

This address several different issues in qed.
The more significant portions:
Patch #1 would cause timeout when qedr utilizes the highest
CIDs availble for it [or when future qede adapters would utilize

Patch #4 fixes a leak of mapped addresses; When iommu is enabled,
offloaded storage protocols might eventually run out of resources
and fail to map additional buffers.
Patches #6,#7 were missing in the initial iSCSI infrastructure
submissions, and would hamper qedi's stability when it reaches

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.

This fixes vlans learning not being enabled for wider ranges than 255.

When we notify peers of potential changes, it's also good to update
IGMP memberships. For example, during VM migration, updating IGMP
memberships will redirect existing multicast streams to the VM at the
new location.

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.

If we have scheduling enabled, we jump directly to insert-and-run.
That's fine, but we run the queue async and we don't pass in information
on whether we can block from this context or not. Fixup both these
cases.

Before this patch, device InJournal will be included in prexor
(SYNDROME_SRC_WANT_DRAIN) but not in reconstruct (SYNDROME_SRC_WRITTEN). So it
will break parity calculation. With srctype == SYNDROME_SRC_WRITTEN, we need
include both dev with non-null ->written and dev with R5_InJournal. This fixes
logic in 1e6d690(md/r5cache: caching phase of r5cache)

Touching HW while clocks are off is a serious error and for instance
breaks suspend functionality. After this patch tilcdc_crtc_update_fb()
always updates the primary plane's framebuffer pointer, increases fb's
reference count and stores vblank event. tilcdc_crtc_update_fb() only
writes the fb's DMA address to HW if the crtc is enabled, as
tilcdc_crtc_enable() takes care of writing the address on enable.
This patch also refactors the tilcdc_crtc_update_fb() a bit. Number of
subsequent small changes had made it almost unreadable. There should
be no other functional changes but checking the CRTC's enable
state. However, the locking goes a bit differently and some of the
redundant checks have been removed in this new version.
The enable_lock should be enough to protect the access to
tilcdc_crtc->enabled. The irq_lock protects the access to last_vblank
and next_fb. The check for vrefresh and last_vblank being valid is
redundant, as the vrefresh should be always valid if the CRTC is
enabled and now last_vblank should be too, because it is initialized
to current time when CRTC raster is enabled. If for some reason the
values are not correctly initialized the division by zero warning is
quite appropriate.
