Pull Qualcomm clk driver updates from Bjorn Andersson:
- Introduces support for the camera clock controller in SM8450 and
the display and gpu clock controllers in SM8350.
- Various fixes, new clocks and USB GDSCs are introduced for IPQ8074
and for MSM8939 a series of fixes for issues introduced by inheriting
the MSM8916 GCC driver is introduced.
- Support for a new type of voteable GDSCs are introduced and put in
use for the SC8280XP PCIe GDSCs. SC8280XP pipe clocks transitioned to
the new phy-mux implementation.
- MSM8996 GCC, the RPM clock driver and some clocks in MSM8994 GCC are
transitioned to use parent_data.
- The topology for Titan (camera) GDSCs on SDM845 and SM8250 are corrected
and MSM8916 gains more possible frequencies for its GP clocks.
- The GCC and tsens handling on MSM8960 is reworked to mimic the design in
IPQ8074 and allow the GCC driver to probe earlier.
- The regulator based mmcx supply for dispcc and videocc is dropped, as
the only upstream target that adapted this interface was transitioned
several kernel versions ago.
- GDSCs found to be enabled at boot will now reflect in the enable
count of the supply, as was done with the regulator supplies
previously.

first waiter
With commit d257cc8cb8d5 ("locking/rwsem: Make handoff bit handling more
consistent"), the writer that sets the handoff bit can be interrupted
out without clearing the bit if the wait queue isn't empty. This disables
reader and writer optimistic lock spinning and stealing.
Now if a non-first writer in the queue is somehow woken up or a new
waiter enters the slowpath, it can't acquire the lock. This is not the
case before commit d257cc8cb8d5 as the writer that set the handoff bit
will clear it when exiting out via the out_nolock path. This is less
efficient as the busy rwsem stays in an unlock state for a longer time.
In some cases, this new behavior may cause lockups as shown in [1] and
[2].
This patch allows a non-first writer to ignore the handoff bit if it
is not originally set or initiated by the first waiter. This patch is
shown to be effective in fixing the lockup problem reported in [1].

If hmm_range_fault() is called with the HMM_PFN_REQ_FAULT flag and a
device private PTE is found, the hmm_range::dev_private_owner page is used
to determine if the device private page should not be faulted in.
However, if the device private page is not owned by the caller,
hmm_range_fault() returns an error instead of calling migrate_to_ram() to
fault in the page.
For example, if a page is migrated to GPU private memory and a RDMA fault
capable NIC tries to read the migrated page, without this patch it will
get an error. With this patch, the page will be migrated back to system
memory and the NIC will be able to read the data.

There was a report that a task is waiting at the
throttle_direct_reclaim. The pgscan_direct_throttle in vmstat was
increasing.
This is a bug where zone_watermark_fast returns true even when the free
is very low. The commit f27ce0e14088 ("page_alloc: consider highatomic
reserve in watermark fast") changed the watermark fast to consider
highatomic reserve. But it did not handle a negative value case which
can be happened when reserved_highatomic pageblock is bigger than the
actual free.
If watermark is considered as ok for the negative value, allocating
contexts for order-0 will consume all free pages without direct reclaim,
and finally free page may become depleted except highatomic free.
Then allocating contexts may fall into throttle_direct_reclaim. This
symptom may easily happen in a system where wmark min is low and other
reclaimers like kswapd does not make free pages quickly.
Handle the negative case by using MIN.

According to "BIOS Information (Type 0) structure" in the SMBIOS
Reference Specification [1], it shows 64K * (n+1) is the size of
the physical device containing the BIOS if the size is less than
16M.
Additionally, we can see the related code in dmidecode [2]:
u64 s = { .l = (code1 + 1) << 6 };
So the output of dmidecode is correct, the output of boardinfo
is wrong, fix it.
By the way, at present no need to consider the size is 16M or
greater on LoongArch, because it is usually 4M or 8M which is
enough to use.

In file ptrace.c, function fpr_set does not copy fcsr data from ubuf
to kbuf. That's the reason why fcsr cannot be modified by ptrace.
This patch fixs this problem and allows users using ptrace to modify
the fcsr.

Current calculation of shared cache size is from the node (die) scope,
but we hope 'lscpu' to show the shared cache size of the whole package
for multi-die chips (e.g., Loongson-3C5000L, which contains 4 dies in
one package). So fix it by multiplying nodes_per_package.

On physical machine we can save power by disabling clock of hot removed
cpu. However as different platforms require different methods to
configure clocks, the code is platform-specific, and probably belongs to
firmware/pmu or cpu regulator, rather than generic arch/loongarch code.
Also, there is no such register on QEMU virt machine since the
clock/frequency regulation is not emulated.
This patch removes the hard-coded clock register accesses in generic
LoongArch cpu hotplug flow.

While B{EQ,NE}Z and B{EQ,NE} are different instructions, and the vastly
expanded range for branch destination does not really matter in the few
cases touched, use the B{EQ,NE}Z where possible for shorter lines and
better consistency (e.g. some places used "BEQ foo, zero", while some
used "BEQ zero, foo").

Some of the assembly code in the LoongArch port likely originated
from a time when the assembler did not support pseudo-instructions like
"move" or "jr", so the desugared form was used and readability suffers
(to a minor degree) as a result.
As the upstream toolchain supports these pseudo-instructions from the
beginning, migrate the existing few usages to them for better
readability.

Some of the assembly in the LoongArch port seem to come from a
prehistoric time, when the assembler didn't even have support for the
ABI names we all come to know and love, thus used raw register numbers
which hampered readability.
The usages are found with a regex match inside arch/loongarch, then
manually adjusted for those non-definitions.

When offset is larger than the size of the bit array, we should not
attempt to access the array as we can perform an access beyond the
end of the array. Fix this by changing the pre-condition.
Using "cmp r2, r1; bhs ..." covers us for the size == 0 case, since
this will always take the branch when r1 is zero, irrespective of
the value of r2. This means we can fix this bug without adding any
additional code!

Some cloud hypervisors do not provide IBPB on very recent CPU processors,
including AMD processors affected by Retbleed.
Using IBPB before firmware calls on such systems would cause a GPF at boot
like the one below. Do not enable such calls when IBPB support is not
present.

Users may request that pages from an OpenCL SVM allocation be migrated
to the GPU with clEnqueueSVMMigrateMem(). In Nouveau this will call into
nouveau_dmem_migrate_vma() to do the migration. If the total range to be
migrated exceeds SG_MAX_SINGLE_ALLOC the pages will be migrated in
chunks of size SG_MAX_SINGLE_ALLOC. However a typo in updating the
starting address means that only the first chunk will get migrated.
Fix the calculation so that the entire range will get migrated if
possible.
