Since commit 4b050ba7a6 ("MIPS: pgtable.h: Implement the
pgprot_writecombine function for MIPS") and commit c4687b15a8 ("MIPS: Fix
definition of pgprot_writecombine()") write-combine vma mapping is
available to be used by kernel subsystems for MIPS. In particular the
uncached accelerated attribute is requested to be set by ioremap_wc()
method and by generic PCI memory pages/ranges mapping methods. The same
is done by the drm_io_prot()/ttm_io_prot() functions in case if
write-combine flag is set for vma's passed for mapping. But for some
reason the pgprot_writecombine() method calling is ifdefed to be a
platform-specific with MIPS system being marked as lacking of one. At the
very least it doesn't reflect the current MIPS platform implementation.
So in order to improve the DRM subsystem performance on MIPS with UCA
mapping enabled, we need to have pgprot_writecombine() called for buffers,
which need store operations being combined. In case if particular MIPS
chip doesn't support the UCA attribute, the mapping will fall back to
noncached.

Expose performance counters through 2 driver specific ioctls: one to
enable/disable the perfcnt block, and one to dump the counter values.
There are discussions to expose global performance monitors (those
counters that can't be retrieved on a per-job basis) in a consistent
way, but this is likely to take time to settle on something that works
for various HW/users.
The ioctls are marked unstable so we can get rid of them when the time
comes. We initally went for a debugfs-based interface, but this was
making the transition to per-FD address space more complicated (we need
to specify the namespace the GPU has to use when dumping the perf
counters), hence the decision to switch back to driver specific ioctls
which are passed the FD they operate on and thus will have a dedicated
address space attached to them.
Other than that, the implementation is pretty simple: it basically dumps
all counters and copy the values to a userspace buffer. The parsing is
left to userspace which has to know the specific layout that's used
by the GPU (layout differs on a per-revision basis).

We plan to expose performance counters through 2 driver specific
ioctls until there's a solution to expose them in a generic way.
In order to be able to deprecate those ioctls when this new
infrastructure is in place we add an unsafe module parameter that
will keep those ioctls hidden unless it's set to true (which also
has the effect of tainting the kernel).
All unstable ioctl handlers should use panfrost_unstable_ioctl_check()
to check whether they're supposed to handle the request or reject it
with ENOSYS.

Pull x86 fixes from Thomas Gleixner:
"The accumulated fixes from this and last week:
- Fix vmalloc TLB flush and map range calculations which lead to
stale TLBs, spurious faults and other hard to diagnose issues.
- Use fault_in_pages_writable() for prefaulting the user stack in the
FPU code as it's less fragile than the current solution
- Use the PF_KTHREAD flag when checking for a kernel thread instead
of current->mm as the latter can give the wrong answer due to
use_mm()
- Compute the vmemmap size correctly for KASLR and 5-Level paging.
Otherwise this can end up with a way too small vmemmap area.
- Make KASAN and 5-level paging work again by making sure that all
invalid bits are masked out when computing the P4D offset. This
worked before but got broken recently when the LDT remap area was
moved.
- Prevent a NULL pointer dereference in the resource control code
which can be triggered with certain mount options when the
requested resource is not available.
- Enforce ordering of microcode loading vs. perf initialization on
secondary CPUs. Otherwise perf tries to access a non-existing MSR
as the boot CPU marked it as available.
- Don't stop the resource control group walk early otherwise the
control bitmaps are not updated correctly and become inconsistent.
- Unbreak kgdb by returning 0 on success from
kgdb_arch_set_breakpoint() instead of an error code.
- Add more Icelake CPU model defines so depending changes can be
queued in other trees"

In vop_crtc_mode_fixup() we fixup the mode to show what we actually
will be able to achieve. However we should base our adjustments on
any previous adjustments that were made.
As an example, the dw_hdmi driver may wish to make some small
adjustments to clock rates in its atomic_check() function. If it
does, it will update the adjusted_mode. We shouldn't throw away those
adjustments.
NOTE: the version of the dw_hdmi driver upstream doesn't _actually_
make such adjustments, but downstream in Chrome OS it does. It is
plausible that one day we'll figure out how to cleanly make that
happen in an upstream-friendly way, so we should prepare by using the
right mode.

When fixing up the clock in vop_crtc_mode_fixup() we're not doing it
quite correctly. Specifically if we've got the true clock 266666667 Hz,
we'll perform this calculation:
266666667 / 1000 => 266666
Later when we try to set the clock we'll do clk_set_rate(266666 *
1000). The common clock framework won't actually pick the proper clock
in this case since it always wants clocks <= the specified one.
Let's solve this by using DIV_ROUND_UP.

Add a microcode loader-specific hotplug vector which comes before

The edid override regression fix took a bit longer since this seems to

The 5.1 mount system rework changed the smackfsdef mount option to
smackfsdefault. This fixes the regression by making smackfsdef treated
the same way as smackfsdefault.
Also fix the smack_param_specs[] to have "smack" prefixes on all the
names. This isn't visible to a user unless they either:
(a) Try to mount a filesystem that's converted to the internal mount API
and that implements the ->parse_monolithic() context operation - and
only then if they call security_fs_context_parse_param() rather than
security_sb_eat_lsm_opts().
There are no examples of this upstream yet, but nfs will probably want
to do this for nfs2 or nfs3.
(b) Use fsconfig() to configure the filesystem - in which case
security_fs_context_parse_param() will be called.
This issue is that smack_sb_eat_lsm_opts() checks for the "smack" prefix
on the options, but smack_fs_context_parse_param() does not.

Since commit d52888aa27 ("x86/mm: Move LDT remap out of KASLR region on
5-level paging") kernel doesn't boot with KASAN on 5-level paging machines.
The bug is actually in early_p4d_offset() and introduced by commit
12a8cc7fcf ("x86/kasan: Use the same shadow offset for 4- and 5-level paging")
early_p4d_offset() tries to convert pgd_val(*pgd) value to a physical
address. This doesn't make sense because pgd_val() already contains the
physical address.
It did work prior to commit d52888aa27 because the result of
"__pa_nodebug(pgd_val(*pgd)) & PTE_PFN_MASK" was the same as "pgd_val(*pgd)
& PTE_PFN_MASK". __pa_nodebug() just set some high bits which were masked
out by applying PTE_PFN_MASK.
After the change of the PAGE_OFFSET offset in commit d52888aa27
__pa_nodebug(pgd_val(*pgd)) started to return a value with more high bits
set and PTE_PFN_MASK wasn't enough to mask out all of them. So it returns a
wrong not even canonical address and crashes on the attempt to dereference
it.
Switch back to pgd_val() & PTE_PFN_MASK to cure the issue.

The value stored in the rate field of struct drm_dp_link should
be the actual link-rate and not the bw_code.
Right now the driver stores the code and converts it to the rate.
So fixup the driver to store the rate itself.

Like the RK3328, RK322x SoCs offer a Synopsis DesignWare HDMI transmitter
and an Innosilicon HDMI PHY.
Add a new dw_hdmi_plat_data struct, rk3228_hdmi_drv_data.
Assign a set of mostly generic rk3228_hdmi_phy_ops functions.
Add dw_hdmi_rk3228_setup_hpd() to enable the HDMI HPD and DDC lines.
