PMU hardware about VM is switched on VM exit to host rather than vCPU
context sched off, PMU is checked and restored on return to VM. It is
not necessary to check PMU on vCPU context sched on callback, since the
request is made on the VM exit entry or VM PMU CSR access abort routine
already.

On LoongArch system, guest PMU hardware is shared by guest and host but
PMU interrupt is separated. PMU is pass-through to VM, and there is PMU
context switch when exit to host and return to guest.
There is optimiation to check whether PMU is enabled by guest. If not,
it is not necessary to return to guest. However, if it is enabled, PMU
context for guest need switch on. Now KVM_REQ_PMU notification is set
on vCPU context switch, but it is missing if there is no vCPU context
switch while PMU is used by guest VM, so fix it.

When timer is fired in oneshot mode, CSR.TVAL will stop with value -1
rather than 0. However when the register CSR.TVAL is restored, it will
continue to count down rather than stop there.
Now the method is to write 0 to CSR.TVAL, wait to count down for 1 cycle
at least, which is 10ns with a timer freq 100MHz, and then retore timer
interrupt status. Here add 2 cycles delay to assure that timer interrupt
is injected.
With this patch, timer selftest case passes to run always.

With secondary MMU page table, if there is a read page fault, the page's
write attribute will not set even if it is writable from master MMU page
table. This logic only works if dirty tracking is enabled, so page table
should be set with _PAGE_WRITE if dirty tracking is disabled.
It reduces extra page fault on secondary MMU page table if a VM finishes
migration, when the master MMU page table is ready and the secondary MMU
page is fresh.

When specifying '-d' for kexec_file_load interface, loaded locations of
kernel/initrd/cmdline etc can be printed out to help debug.
Commit eb7622d908 ("kexec_file, riscv: print out debugging message if
required") fixes the same issue on RISC-V.
So, remove kexec_image_info() because the content has been printed out
in generic code.
And on Loongson-3A5000, the printed messages look like below:

The kexec_buf structure was previously declared without initialization.
commit bf454ec31a ("kexec_file: allow to place kexec_buf randomly")
added a field that is always read but not consistently populated by all
architectures. This un-initialized field will contain garbage.
This is also triggering a UBSAN warning when the uninitialized data is
accessed:
------------[ cut here ]------------
UBSAN: invalid-load in ./include/linux/kexec.h:210:10
load of value 252 is not a valid value for type '_Bool'
Zero-initializing kexec_buf at declaration ensures all fields are
cleanly set, preventing future instances of uninitialized memory being
used.

Now if the PTE/PMD is dirty with _PAGE_DIRTY but without _PAGE_MODIFIED,
after {pte,pmd}_modify() we lose _PAGE_DIRTY, then {pte,pmd}_dirty()
return false and lead to data loss. This can happen in certain scenarios
such as HW PTW doesn't set _PAGE_MODIFIED automatically, so here we need
_PAGE_MODIFIED to record the dirty status (_PAGE_DIRTY).
The new modification involves checking whether the original PTE/PMD has
the _PAGE_DIRTY flag. If it exists, the _PAGE_MODIFIED bit is also set,
ensuring that the {pte,pmd}_dirty() interface can always return accurate
information.

Now there 5 places which calculate max_pfn & max_low_pfn:
1. in fdt_setup() for FDT systems;
2. in memblock_init() for ACPI systems;
3. in init_numa_memory() for NUMA systems;
4. in arch_mem_init() to recalculate for "mem=" cmdline;
5. in paging_init() to recalculate for NUMA systems.
Since memblock_init() is called both for ACPI and FDT systems, move the
calculation out of the for_each_efi_memory_desc() loop can eliminate the
first case. The last case is very questionable (may be derived from the
MIPS/Loongson code) and breaks the "mem=" cmdline, so should be removed.
And then the NUMA version of paging_init() can be also eliminated.
After consolidation there are 3 places of calculation:
1. in memblock_init() for both ACPI and FDT systems;
2. in init_numa_memory() to recalculate for NUMA systems;
3. in arch_mem_init() to recalculate for the "mem=" cmdline.
For all cases the calculation is:
max_pfn = PFN_DOWN(memblock_end_of_DRAM());
max_low_pfn = min(PFN_DOWN(HIGHMEM_START), max_pfn);

LoongArch's MSG interrupt features are used across multiple subsystems.
Clarify these features to avoid misuse, existing users will be adjusted
if necessary.
MSGINT: Infrastructure, means the CPU core supports message interupts.
Indicated by CPUCFG1.MSGINT.
AVECINT: AVEC interrupt controller based on MSGINT, means the CPU chip
supports direct message interrupts. Indicated by IOCSR.FEATURES.DMSI.
REDIRECTINT: REDIRECT interrupt controller based on MSGINT and AVECINT,
means the CPU chip supports redirect message interrupts. Indicated by
IOCSR.FEATURES.RMSI.
For example:
Loongson-3A5000/3C5000 doesn't support MSGINT/AVECINT/REDIRECTINT;
Loongson-3A6000 supports MSGINT but doesn't support AVECINT/REDIRECTINT;
Loongson-3C6000 supports MSGINT/AVECINT/REDIRECTINT.
