2d2c395217 LoongArch: Use generic BUG() handler
Inspired by commit 9fb7410f955("arm64/BUG: Use BRK instruction for
generic BUG traps"), do similar for LoongArch to use generic BUG()
handler.

This patch uses the BREAK software breakpoint instruction to generate
a trap instead, similarly to most other arches, with the generic BUG
code generating the dmesg boilerplate.

This allows bug metadata to be moved to a separate table and reduces
the amount of inline code at BUG() and WARN() sites. This also avoids
clobbering any registers before they can be dumped.

To mitigate the size of the bug table further, this patch makes use of
the existing infrastructure for encoding addresses within the bug table
as 32-bit relative pointers instead of absolute pointers.

(Note: this limits the max kernel size to 2GB.)

d279134168 LoongArch: Use TLB for ioremap()
We can support more cache attributes (e.g., CC, SUC and WUC) and page
protection when we use TLB for ioremap(). The implementation is based
on GENERIC_IOREMAP.

The existing simple ioremap() implementation has better performance so
we keep it and introduce ARCH_IOREMAP to control the selection.

We move pagetable_init() earlier to make early ioremap() works, and we
modify the PCI ecam mapping because the TLB-based version of ioremap()
will actually take the size into account.

b61a40afca LoongArch: Refactor cache probe and flush methods
Current cache probe and flush methods have some drawbacks:
1, Assume there are 3 cache levels and only 3 levels;
2, Assume L1 = I + D, L2 = V, L3 = S, V is exclusive, S is inclusive.

However, the fact is I + D, I + D + V, I + D + S and I + D + V + S are
all valid. So, refactor the cache probe and flush methods to adapt more
types of cache hierarchy.

a2a84e3633 LoongArch: mm: Refactor TLB exception handlers
This patch simplifies TLB load, store and modify exception handlers:

1. Reduce instructions, such as alu/csr and memory access;
2. Execute tlb search instruction only in the fast path;
3. Return directly from the fast path for both normal and huge pages;
4. Re-tab the assembly for better vertical alignment.

And fixes the concurrent modification issue of fast path for huge pages.

This issue will occur in the following steps:

   CPU-1 (In TLB exception)         CPU-2 (In THP splitting)
1: Load PMD entry (HUGE=1)
2: Goto huge path
3:                                  Store PMD entry (HUGE=0)
4: Reload PMD entry (HUGE=0)
5: Fill TLB entry (PA is incorrect)

This patch also slightly improves the TLB processing performance:

* Normal pages: 2.15%, Huge pages: 1.70%.

  #include <stdlib.h>
  #include <unistd.h>
  #include <sys/mman.h>

        size_t mem_size;

        int i;

                return -1;
        }

        page_size = sysconf(_SC_PAGESIZE);
        flags = MAP_PRIVATE | MAP_ANONYMOUS;
        mem_size = strtoul(argv[1], NULL, 10);
        if (argc > 2)
                flags |= MAP_HUGETLB;

59b3d4a9b0 LoongArch: Support R_LARCH_GOT_PC_{LO12,HI20} in modules
GCC >= 13 and GNU assembler >= 2.40 use these relocations to address
external symbols, so we need to add them.

Let the module loader emit GOT entries for data symbols so we would be
able to handle GOT relocations. The GOT entry is just the data's symbol
address.

In module.lds, emit a stub .got section for a section header entry. The
actual content of the section entry will be filled at runtime by module_
frob_arch_sections().

11cd8a6483 LoongArch: Adjust symbol addressing for AS_HAS_EXPLICIT_RELOCS
If explicit relocation hints are used by the toolchain, -Wa,-mla-*
options will be useless for the C code. So only use them for the
!CONFIG_AS_HAS_EXPLICIT_RELOCS case.

Replace "la" with "la.pcrel" in head.S to keep the semantic consistent
with new and old toolchains for the low level startup code.

For per-CPU variables, the "address" of the symbol is actually an offset
from $r21. The value is near the loading address of main kernel image,
but far from the loading address of modules. So we use model("extreme")
attibute to tell the compiler that a PC-relative addressing with 32-bit
offset is not sufficient for local per-CPU variables.

The behavior with different assemblers and compilers are summarized in
the following table:

AS has            CC has
explicit relocs   explicit relocs * Behavior
==============================================================
No                No                Use la.* macros.
                                    No change from Linux 6.0.
--------------------------------------------------------------
No                Yes               Disable explicit relocs.
                                    No change from Linux 6.0.
--------------------------------------------------------------
Yes               No                Not supported.
--------------------------------------------------------------
Yes               Yes               Enable explicit relocs.
                                    No -Wa,-mla* options used.
==============================================================
*: We assume CC must have model attribute if it has explicit relocs.
   Both features are added in GCC 13 development cycle, so any GCC
   release >= 13 should be OK. Using early GCC 13 development snapshots
   may produce modules with unsupported relocations.

Commit ac7c3e4ff4 ("compiler: enable CONFIG_OPTIMIZE_INLINING

In case of __xchg()/__cmpxchg() this would cause to reference
BUILD_BUG(), which is an error case for catching bugs and will not
happen for correct code, if __xchg()/__cmpxchg() is inlined.

This bug can be produced with CONFIG_DEBUG_SECTION_MISMATCH enabled,
and the solution is similar to below commits:

Move local_flush_tlb_all() earlier (just after setup_ptwalker() and
before page allocation). This can avoid stale TLB entries misguiding

BTW, move output_pgtable_bits_defines() into tlb_init() since it has

 	- thunderbolt bugfix for plug event delays
 	- typec runtime warning removal
 	- dwc3 st driver bugfix.  Note, a follow-on fix for this will

 	  be sufficient for now.

e5fa173f9a Here's the last batch of clk driver fixes for this release. These
patches fix serious problems, for example, i.MX has an issue where
 changing the NAND clk frequency hangs the system. On Allwinner H6 the
 GPU is being overclocked which could lead to long term hardware damage.
 And finally on some Broadcom SoCs the serial console stopped working
 because the clk tree hierarchy description got broken by an inadvertant
 DT node name change. That's fixed by using 'clock-output-names' to
 generate a stable and unique name for clks so the framework can properly
 link things up.
 
 There's also a couple build fixes in here. One to fix CONFIG_OF=n builds
 and one to avoid an array out of bounds bug that happens during clk
 registration on microchip. I hope that KASAN would have found that OOB
 problem, but probably KASAN wasn't attempted. Instead LLVM/clang
 compilation caused an oops, while GCC didn't.

  inadvertant DT node name change. That's fixed by using
  'clock-output-names' to generate a stable and unique name for clks so
  the framework can properly link things up.

  There's also a couple build fixes in here. One to fix CONFIG_OF=n
  builds and one to avoid an array out of bounds bug that happens during
  clk registration on microchip. I hope that KASAN would have found that
  OOB problem, but probably KASAN wasn't attempted. Instead LLVM/clang
  compilation caused an oops, while GCC didn't"

c816f2e981 perf tools fixes for v6.0: 5th batch
- Fail the 'perf test record' entry on error, fixing a regression where just
   setup stuff like allocating memory and not the actual things being tested failed.
 
 - Fixup disabling of -Wdeprecated-declarations for the python scripting engine, the
   previous attempt had a brown paper bag thinko.
 
 - Fix branch stack sampling test to include sanity check for branch filter on PowerPC.
 
 - Update is_ignored_symbol function to match the kernel ignored list, fixing running
   the 'perf test' entry that compares resolving symbols from kallsyms to resolving from
   vmlinux.
 
 - Augment the data source type with ARM's neoverse_spe list, the previous code
   was limited in its search resolving the data source.
 
 - Fix some clang 5 variable set but unused cases.
 
 - Get a perf cgroup more portably in BPF as the __builtin_preserve_enum_value builtin is
   not available in older versions of clang. In those cases we can forgo BPF's CO-RE (Compile
   Once, Run Everywhere).
 
 - More Fixes for Intel's hybrid CPU model.
