Move en7523_register_clocks routine in hw_init callback.
Introduce en7523_clk_hw_init callback for EN7523 SoC.
This is a preliminary patch to differentiate IO mapped region between
EN7523 and EN7581 SoCs in order to access chip-scu IO region
<0x1fa20000 0x384> on EN7581 SoC as syscon device since it contains
miscellaneous registers needed by multiple devices (clock, pinctrl ..).

REG_PCIE*_MEM and REG_PCIE*_MEM_MASK regs (PBUS_CSR memory region) are not
part of the scu block on the EN7581 SoC and they are used to select the
PCIE ports on the PBUS, so remove this configuration from the clock driver
and set these registers in the PCIE host driver instead.

clk_mt6735_apmixed_probe()
If an error occurs after a successful mtk_alloc_clk_data(),
mtk_free_clk_data() should be called, as already done in the .remove()

Original architecture clock code from where this driver was derived did not
include nothing related to mmc clocks. OpenWRT people started to use mtk-sd
upstream driver recently and they were forced to use a dts 'fixed-clock'
node with 48 MHz clock:
- https://github.com/openwrt/openwrt/pull/15896
The proper thing to do to avoid that is to add the mmc related clocks to the
driver to avoid a dts with fixed clocks nodes. The minimal documentation in
the mt7620 programming guide says that there is a BBP_PLL clock of 480 MHz
derived from the 40 MHz XTAL and from there a clock divider by ten produces
the desired SDHC clock of 48 MHz for the mmc. Hence add a fixed clock 'bbppll'
and factor clock 'sdhc' ten divider child to properly set the 'mmc' peripheral
clock with the desired 48 Mhz rate.

Base clocks are the first in being probed and are real dependencies of the
rest of fixed, factor and peripheral clocks. For old ralink SoCs RT2880,
RT305x and RT3883 'xtal' must be defined first since in any other case,
when fixed clocks are probed they are delayed until 'xtal' is probed so the
following warning appears:

When this driver was mainlined we could not find any active users of old
ralink SoCs so we cannot perform any real tests for them. Now, one user
of a Belkin f9k1109 version 1 device which uses RT3883 SoC appeared and
reported some issues in openWRT:
- https://github.com/openwrt/openwrt/issues/16054
Thus, define a 'rt2880_xtal_recalc_rate()' just returning the expected
frequency 40Mhz and use it along the old ralink SoCs to have a correct
boot trace with no warnings and a working clock plan from the beggining.

Clock plan for Ralink SoC RT3883 needs an extra 'periph' clock to properly
set some peripherals that has this clock as their parent. When this driver
was mainlined we could not find any active users of this SoC so we cannot
perform any real tests for it. Now, one user of a Belkin f9k1109 version 1
device which uses this SoC appear and reported some issues in openWRT:
- https://github.com/openwrt/openwrt/issues/16054
The peripherals that are wrong are 'uart', 'i2c', 'i2s' and 'uartlite' which
has a not defined 'periph' clock as parent. Hence, introduce it to have a
properly working clock plan for this SoC.

Same as MT8195, MT8188 GPU clock is primarly supplied by the dedicated
mfgpll. The clock "mfg_core_tmp" is only used as an alt clock when
setting mfgpll clock rate.
If we keep the univpll parents from mfg_core_tmp, when setting
GPU frequency to 390000000, the common clock framework would switch
the parent to univpll, instead of setting mfgpll to 390000000:
mfgpll 0 0 0 949999756
univpll 2 2 0 2340000000
univpll_d6 1 1 0 390000000
top_mfg_core_tmp 1 1 0 390000000
mfg_ck_fast_ref 1 1 0 390000000
mfgcfg_bg3d 1 1 0 390000000
This results in failures when subsequent devfreq operations need to
switch to other frequencies. So remove univpll from the parent list.
This solution is taken from commit 72d38ed720e9 ("clk: mediatek:
clk-mt8195-topckgen: Drop univplls from mfg mux parents")

Commit 0f471d31e5e8 ("clk: mediatek: Split MT8195 clock drivers and allow

Among those, the config options COMMON_CLK_MT8195_AUDSYS and
COMMON_CLK_MT8195_MSDC have no reference in the source tree and are not
used in the Makefile to include a specific file.
Drop the dead config options COMMON_CLK_MT8195_AUDSYS and

The cpu_emergency_register_virt_callback() function is used
unconditionally by the x86 kvm code, but it is declared (and defined)
conditionally:
#if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD)
void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback);
...
leading to a build error when neither KVM_INTEL nor KVM_AMD support is
enabled:
arch/x86/kvm/x86.c: In function ‘kvm_arch_enable_virtualization’:
arch/x86/kvm/x86.c:12517:9: error: implicit declaration of function ‘cpu_emergency_register_virt_callback’ [-Wimplicit-function-declaration]

12522 | cpu_emergency_unregister_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fix the build by defining empty helper functions the same way the old
cpu_emergency_disable_virtualization() function was dealt with for the
same situation.
Maybe we could instead have made the call sites conditional, since the
callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak
fallback. I'll leave that to the kvm people to argue about, this at
least gets the build going for that particular config.

Pull more bcachefs updates from Kent Overstreet:
"Assorted minor syzbot fixes, and for bigger stuff:
Fix two disk accounting rewrite bugs:
- Disk accounting keys use the version field of bkey so that journal
replay can tell which updates have been applied to the btree.
This is set in the transaction commit path, after we've gotten our
journal reservation (and our time ordering), but the
BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay
uses was incorrectly skipping this for new updates generated prior
to journal replay.
This fixes the underlying cause of an assertion pop in
disk_accounting_read.
- A couple of fixes for disk accounting + device removal.
Checking if acocunting replicas entries were marked in the
superblock was being done at the wrong point, when deltas in the
journal could still zero them out, and then additionally we'd try
to add a missing replicas entry to the superblock without checking
if it referred to an invalid (removed) device.
A whole slew of repair fixes:
- fix infinite loop in propagate_key_to_snapshot_leaves(), this fixes
an infinite loop when repairing a filesystem with many snapshots
- fix incorrect transaction restart handling leading to occasional
"fsck counted ..." warnings
- fix warning in __bch2_fsck_err() for bkey fsck errors
- check_inode() in fsck now correctly checks if the filesystem was
clean
- there shouldn't be pending logged ops if the fs was clean, we now

The isomorphism neg_if_exp negates the test of a ?: conditional,
making it unnecessary to have an explicit case for a negated test
with the branches inverted.
At the same time, we can disable neg_if_exp in cases where a
different API function may be more suitable for a negated test.
Finally, in the non-patch cases, E matches an expression with
parentheses around it, so there is no need to mention ()
explicitly in the pattern. The () are still needed in the patch
cases, because we want to drop them, if they are present.

The parentheses are only needed if there is a disjunction, ie a
set of possible changes. If there is only one pattern, we can
remove these parentheses. Just like the format:
- x
+ y
not:
(
- x
+ y
)

Pull x86 kvm updates from Paolo Bonzini:
"x86:
- KVM currently invalidates the entirety of the page tables, not just
those for the memslot being touched, when a memslot is moved or
deleted.
This does not traditionally have particularly noticeable overhead,
but Intel's TDX will require the guest to re-accept private pages
if they are dropped from the secure EPT, which is a non starter.
Actually, the only reason why this is not already being done is a
bug which was never fully investigated and caused VM instability
with assigned GeForce GPUs, so allow userspace to opt into the new
behavior.
- Advertise AVX10.1 to userspace (effectively prep work for the
"real" AVX10 functionality that is on the horizon)
- Rework common MSR handling code to suppress errors on userspace
accesses to unsupported-but-advertised MSRs
This will allow removing (almost?) all of KVM's exemptions for
userspace access to MSRs that shouldn't exist based on the vCPU
model (the actual cleanup is non-trivial future work)
- Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC)
splits the 64-bit value into the legacy ICR and ICR2 storage,
whereas Intel (APICv) stores the entire 64-bit value at the ICR
offset
- Fix a bug where KVM would fail to exit to userspace if one was
triggered by a fastpath exit handler
- Add fastpath handling of HLT VM-Exit to expedite re-entering the
guest when there's already a pending wake event at the time of the
exit
- Fix a WARN caused by RSM entering a nested guest from SMM with
invalid guest state, by forcing the vCPU out of guest mode prior to
signalling SHUTDOWN (the SHUTDOWN hits the VM altogether, not the
nested guest)
- Overhaul the "unprotect and retry" logic to more precisely identify
cases where retrying is actually helpful, and to harden all retry
paths against putting the guest into an infinite retry loop
- Add support for yielding, e.g. to honor NEED_RESCHED, when zapping
rmaps in the shadow MMU
- Refactor pieces of the shadow MMU related to aging SPTEs in
prepartion for adding multi generation LRU support in KVM
- Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is
enabled, i.e. when the CPU has already flushed the RSB
- Trace the per-CPU host save area as a VMCB pointer to improve
readability and cleanup the retrieval of the SEV-ES host save area
- Remove unnecessary accounting of temporary nested VMCB related
allocations
- Set FINAL/PAGE in the page fault error code for EPT violations if
and only if the GVA is valid. If the GVA is NOT valid, there is no
guest-side page table walk and so stuffing paging related metadata
is nonsensical
- Fix a bug where KVM would incorrectly synthesize a nested VM-Exit
instead of emulating posted interrupt delivery to L2
- Add a lockdep assertion to detect unsafe accesses of vmcs12
structures
- Harden eVMCS loading against an impossible NULL pointer deref
(really truly should be impossible)
- Minor SGX fix and a cleanup
- Misc cleanups
Generic:
- Register KVM's cpuhp and syscore callbacks when enabling
virtualization in hardware, as the sole purpose of said callbacks
is to disable and re-enable virtualization as needed
- Enable virtualization when KVM is loaded, not right before the
first VM is created
Together with the previous change, this simplifies a lot the logic
of the callbacks, because their very existence implies
virtualization is enabled
- Fix a bug that results in KVM prematurely exiting to userspace for
coalesced MMIO/PIO in many cases, clean up the related code, and
add a testcase
- Fix a bug in kvm_clear_guest() where it would trigger a buffer
overflow _if_ the gpa+len crosses a page boundary, which thankfully
is guaranteed to not happen in the current code base. Add WARNs in
more helpers that read/write guest memory to detect similar bugs
Selftests:
- Fix a goof that caused some Hyper-V tests to be skipped when run on
bare metal, i.e. NOT in a VM
- Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES
guest
- Explicitly include one-off assets in .gitignore. Past Sean was
completely wrong about not being able to detect missing .gitignore
entries
- Verify userspace single-stepping works when KVM happens to handle a
VM-Exit in its fastpath
- Misc cleanups"
