Huacai Chen eeeeaafa62 LoongArch: Use correct accessor to read FWPC/MWPC
CSR.FWPC and CSR.MWPC are 32bit registers, so use csr_read32() rather
than csr_read64() to read the values of FWPC/MWPC.

Tiezhu Yang 4c8a7c9827 LoongArch: Refine the init_hw_perf_events() function
(1) Use the existing CPUCFG6_PMNUM_SHIFT macro definition instead of
the magic value 4 to get the PMU number.

(2) Detect the value of PMU bits via CPUCFG instruction according to
the ISA manual instead of hard-coded as 64, because the value may be
different for various micro-architectures.

Remove the unnecessary __GFP_HIGHMEM masking in pud_alloc_one(), which
was introduced with commit 382739797f ("loongarch: convert various

Tianyang Zhang a073d637c8 LoongArch: Let {pte,pmd}_modify() record the status of _PAGE_DIRTY
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.

Huacai Chen ce5ad03e45 LoongArch: Consolidate max_pfn & max_low_pfn calculation
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);

Huacai Chen 43a9e6a10b LoongArch: Consolidate early_ioremap()/ioremap_prot()
1. Use phys_addr_t instead of u64, which can work for both 32/64 bits.
2. Check whether the input physical address is above TO_PHYS_MASK (and
   return NULL if yes) for the DMW version.

Note: In theory early_ioremap() also need the TO_PHYS_MASK checking, but
the UEFI BIOS pass some DMW virtual addresses.

Huacai Chen 4e67526840 LoongArch: Use physical addresses for CSR_MERRENTRY/CSR_TLBRENTRY
Now we use virtual addresses to fill CSR_MERRENTRY/CSR_TLBRENTRY, but
hardware hope physical addresses. Now it works well because the high
bits are ignored above PA_BITS (48 bits), but explicitly use physical
addresses can avoid potential bugs. So fix it.

Huacai Chen f28abb9f96 LoongArch: Clarify 3 MSG interrupt features
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.

It is possible to force a specific version of python to be used when
building the kernel by passing PYTHON3= on the make command line.
However kernel-doc.py is currently called with python3 hard-coded and
thus ignores this setting.

Use $(PYTHON3) to run $(KERNELDOC) so that the desired version of
python is used.

Linus Torvalds 5b95a50001 Merge tag 'trace-v6.18-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:

 - Check for reader catching up in ring_buffer_map_get_reader()

   If the reader catches up to the writer in the memory mapped ring
   buffer then calling rb_get_reader_page() will return NULL as there's
   no pages left. But this isn't checked for before calling
   rb_get_reader_page() and the return of NULL causes a warning.

   If it is detected that the reader caught up to the writer, then
   simply exit the routine

 - Fix memory leak in histogram create_field_var()

   The couple of the error paths in create_field_var() did not properly
   clean up what was allocated. Make sure everything is freed properly
   on error

 - Fix help message of tools latency_collector

   The help message incorrectly stated that "-t" was the same as
   "--threads" whereas "--threads" is actually represented by "-e"

Zhang Chujun 53afec2c8f tracing/tools: Fix incorrcet short option in usage text for --threads
The help message incorrectly listed '-t' as the short option for
--threads, but the actual getopt_long configuration uses '-e'.
This mismatch can confuse users and lead to incorrect command-line
usage. This patch updates the usage string to correctly show:
	"-e, --threads NRTHR"
to match the implementation.

Note: checkpatch.pl reports a false-positive spelling warning on
'Run', which is intentional.

Jouni Högander b11a020d91 drm/xe: Do clean shutdown also when using flr

shutdown. This is causing random warnings from pending related works as the
underlying hardware is reset in the middle of their execution.

Zilin Guan 80f0d631dc tracing: Fix memory leaks in create_field_var()
The function create_field_var() allocates memory for 'val' through
create_hist_field() inside parse_atom(), and for 'var' through
create_var(), which in turn allocates var->type and var->var.name
internally. Simply calling kfree() to release these structures will
result in memory leaks.

Use destroy_hist_field() to properly free 'val', and explicitly release
the memory of var->type and var->var.name before freeing 'var' itself.

Steven Rostedt aa997d2d2a ring-buffer: Do not warn in ring_buffer_map_get_reader() when reader catches up
The function ring_buffer_map_get_reader() is a bit more strict than the
other get reader functions, and except for certain situations the
rb_get_reader_page() should not return NULL. If it does, it triggers a
warning.

This warning was triggering but after looking at why, it was because
another acceptable situation was happening and it wasn't checked for.

If the reader catches up to the writer and there's still data to be read
on the reader page, then the rb_get_reader_page() will return NULL as
there's no new page to get.

In this situation, the reader page should not be updated and no warning
should trigger.
