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.

GNU as >= 2.40 and GCC >= 13 will support using explicit relocation hints in the assembly code, instead of la.* macros. The usage of explicit relocation hints can improve code generation so it's enabled by default by GCC >= 13. Introduce a Kconfig option AS_HAS_EXPLICIT_RELOCS as the switch for "use explicit relocation hints or not".

Commit ac7c3e4f ("compiler: enable CONFIG_OPTIMIZE_INLINING forcibly") allows compiler to uninline functions marked as 'inline'. 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: 46f16195 ("MIPS: include: Mark __xchg as __always_inline"), 88356d09 ("MIPS: include: Mark __cmpxchg as __always_inline").

Move local_flush_tlb_all() earlier (just after setup_ptwalker() and before page allocation). This can avoid stale TLB entries misguiding the later page allocation. Without this patch the second kernel of kexec/kdump fails to boot SMP. BTW, move output_pgtable_bits_defines() into tlb_init() since it has nothing to do with tlb handler setup.

Now io master CPUs are not hotpluggable on LoongArch, but in the current code only /sys/devices/system/cpu/cpu0/online is not created. Let us set the hotpluggable field of all the io master CPUs as 0, then prevent to create sysfs control file for all the io master CPUs which confuses some user space tools.

Pull clk driver fixes from Stephen Boyd: "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.

This reverts commit e4f0a7ec. When using this new interface, both efi_pstore and ramoops backends are unable to properly decompress dmesg if using zstd, lz4 and lzo algorithms (and maybe more). It does succeed with deflate though. The message observed in the kernel log is: [2.328828] pstore: crypto_acomp_decompress failed, ret = -22! The pstore infrastructure is able to collect the dmesg with both backends tested, but since decompression fails it's unreadable. With this revert everything is back to normal.
