drm/rockchip: Fix return type of cdn_dp_connector_mode_valid
The mode_valid field in drm_connector_helper_funcs is expected to be of
type:
enum drm_mode_status (* mode_valid) (struct drm_connector *connector,
struct drm_display_mode *mode);
The mismatched return type breaks forward edge kCFI since the underlying

The return type of cdn_dp_connector_mode_valid should be changed from

drm/gma500: Fix (vblank) IRQs not working after suspend/resume
Fix gnome-shell (and other page-flip users) hanging after suspend/resume
because of the gma500's IRQs not working.
This fixes 2 problems with the IRQ handling:
1. gma_power_off() calls gma_irq_uninstall() which does a free_irq(), but
gma_power_on() called gma_irq_preinstall() + gma_irq_postinstall() which
do not call request_irq. Replace the pre- + post-install calls with
gma_irq_install() which does prep + request + post.
2. After fixing 1. IRQs still do not work on a Packard Bell Dot SC (Intel
Atom N2600, cedarview) netbook.
Cederview uses MSI interrupts and it seems that the BIOS re-configures
things back to normal APIC based interrupts during S3 suspend. There is
some MSI PCI-config registers save/restore code which tries to deal with
this, but on the Packard Bell Dot SC this is not sufficient to restore
MSI IRQ functionality after a suspend/resume.
Replace the PCI-config registers save/restore with pci_disable_msi() on
suspend + pci_enable_msi() on resume. Fixing e.g. gnome-shell hanging.

drm/gma500: Fix BUG: sleeping function called from invalid context errors
gma_crtc_page_flip() was holding the event_lock spinlock while calling
crtc_funcs->mode_set_base() which takes ww_mutex.
The only reason to hold event_lock is to clear gma_crtc->page_flip_event
on mode_set_base() errors.
Instead unlock it after setting gma_crtc->page_flip_event and on
errors re-take the lock and clear gma_crtc->page_flip_event it
it is still set.

VPP_WRAP_OSD1_MATRIX_COEF22.Coeff22 is documented as being bits 0-12,

Without this the output tends to have a pink hue, changing it results
in better color accuracy.
The vendor kernel doesn't use this register. However the code which
sets VIU2_OSD1_MATRIX_COEF22 also uses bits 0-12. There is a slightly
different style of registers for configuring some of the other matrices,

drm/panel-edp: Fix delays for Innolux N116BCA-EA1
Commit
52824ca4502d ("drm/panel-edp: Better describe eDP panel delays")
clarified the various delays used for eDP panels, tying them to the eDP
panel timing diagram.
For Innolux N116BCA-EA1, .prepare_to_enable would be:
t4_min + t5_min + t6_min + max(t7_max, t8_min)
Since t4_min and t5_min are both 0, the panel can use either .enable or
.prepare_to_enable.
As .enable is better defined, switch to using .enable for this panel.
Also add .disable = 50, based on the datasheet's t9_min value. This
effectively makes the delays the same as delay_200_500_e80_d50.

Ghost BO is released with non-empty bulk move object. There is a
warning trace:

dma-buf/dma-resv: check if the new fence is really later
Previously when we added a fence to a dma_resv object we always
assumed the the newer than all the existing fences.
With Jason's work to add an UAPI to explicit export/import that's not
necessary the case any more. So without this check we would allow
userspace to force the kernel into an use after free error.
Since the change is very small and defensive it's probably a good
idea to backport this to stable kernels as well just in case others
are using the dma_resv object in the same way.

drm/gem: Fix GEM handle release errors
Currently we are assuming a one to one mapping between dmabuf and
GEM handle when releasing GEM handles.
But that is not always true, since we would create extra handles for the
GEM obj in cases like gem_open() and getfb{,2}().
A similar issue was reported at:
https://lore.kernel.org/all/
20211105083308.392156-1-jay.xu@rock-chips.com/
Another problem is that the imported dmabuf might not always have
gem_obj->dma_buf set, which would cause leaks in
drm_gem_remove_prime_handles().
Let's fix these for now by using handle to find the exact map to remove.

drm/vc4: hdmi: Rework power up
The current code tries to handle the case where CONFIG_PM isn't selected
by first calling our runtime_resume implementation and then properly
report the power state to the runtime_pm core.
This allows to have a functionning device even if pm_runtime_get_*
functions are nops.
However, the device power state if CONFIG_PM is enabled is
RPM_SUSPENDED, and thus our vc4_hdmi_write() and vc4_hdmi_read() calls
in the runtime_pm hooks will now report a warning since the device might
not be properly powered.
Even more so, we need CONFIG_PM enabled since the previous RaspberryPi
have a power domain that needs to be powered up for the HDMI controller
to be usable.
The previous patch has created a dependency on CONFIG_PM, now we can
just assume it's there and only call pm_runtime_resume_and_get() to make
sure our device is powered in bind.

perf test: Refactor shell tests allowing subdirs
This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.
To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.
This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).
It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).
This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.

perf jevents: Fold strings optimization
If a shorter string ends a longer string then the shorter string may
reuse the longer string at an offset. For example, on x86 the event
arith.cycles_div_busy and cycles_div_busy can be folded, even though
they have difference names the strings are identical after 6
characters. cycles_div_busy can reuse the arith.cycles_div_busy string
at an offset of 6.
In pmu-events.c this looks like the following where the 'also:' lists
folded strings:
/* offset=177541 */ "arith.cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000" /* also: cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000 */
As jevents.py combines multiple strings for an event into a larger
string, the amount of folding is minimal as all parts of the event must
align. Other organizations can benefit more from folding, but lose space
by say recording more offsets.

perf jevents: Compress the pmu_events_table
The pmu_events array requires 15 pointers per entry which in position
independent code need relocating. Change the array to be an array of
offsets within a big C string. Only the offset of the first variable is
required, subsequent variables are stored in order after the \0
terminator (requiring a byte per variable rather than 4 bytes per
offset).
The file size savings are:
no jevents - the same 19,788,464bytes
x86 jevents - ~16.7% file size saving 23,744,288bytes vs 28,502,632bytes
all jevents - ~19.5% file size saving 24,469,056bytes vs 30,379,920bytes
default build options plus NO_LIBBFD=1.
For example, the x86 build savings come from .rela.dyn and
.data.rel.ro becoming smaller by 3,157,032bytes and 3,042,016bytes
respectively. .rodata increases by 1,432,448bytes, giving an overall
4,766,600bytes saving.
To make metric strings more shareable, the topic is changed from say
'skx metrics' to just 'metrics'.
To try to help with the memory layout the pmu_events are ordered as used
by perf qsort comparator functions.

perf pmu-events: Don't assume pmu_event is an array
The current code assumes that a struct pmu_event can be iterated over
forward until a NULL pmu_event is encountered.
This makes it difficult to refactor pmu_event.
Add a loop function taking a callback function that's passed the struct
pmu_event.
This way the pmu_event is only needed for one element and not an entire
array.
Switch existing code iterating over the pmu_event arrays to use the new
loop function pmu_events_table_for_each_event.

RISC-V: KVM: Support sstc extension
Sstc extension allows the guest to program the vstimecmp CSR directly
instead of making an SBI call to the hypervisor to program the next
event. The timer interrupt is also directly injected to the guest by
the hardware in this case. To maintain backward compatibility, the
hypervisors also update the vstimecmp in an SBI set_time call if
the hardware supports it. Thus, the older kernels in guest also
take advantage of the sstc extension.

Commit
6f8191fdf41d ("block: simplify disk shutdown") removed the call
to blk_get_queue() during gendisk allocation but missed to remove the
corresponding cleanup code blk_put_queue() for it. Thus, if the gendisk
allocation fails, the request_queue refcount gets decremented and
reaches 0, causing blk_mq_release() to be called with a hctx still
alive. That triggers a WARNING report, as found by syzkaller:
