2022-03-15fs: Add aops->launder_folioMatthew Wilcox (Oracle)
Since the only difference between ->launder_page and ->launder_folio is the type of the pointer, these can safely use a union without affecting bisectability.

2022-03-15nfs: Convert from invalidatepage to invalidate_folioMatthew Wilcox (Oracle)
Print the folio index instead of the pointer, since this is more useful. We also don't need to use page_file_mapping() as we do not invalidate swapcache pages. Since this is the only caller of nfs_wb_page_cancel(), convert it to nfs_wb_folio_cancel().

As it turns out, these laptops have 2 thermal profile versions. A previous patch added support for v0, this patch adds support for v1 thermal policies that are in use on some devices. We obtain the thermal policy version by querying the get system design data WMI call and looking at the fourth byte it returns, except if the system board DMI Board ID is in a specific array that the windows command center app overrides to thermal policy v0 for some reason.

2022-03-15platform/x86: hp-wmi: Changing bios_args.data to be dynamically allocatedJorge Lopez
The purpose of this patch is to remove 128 bytes buffer limitation imposed in bios_args structure. A limiting factor discovered during this investigation was the struct bios_args.data size restriction. The data member size limits all possible WMI commands to those requiring buffer size of 128 bytes or less. Several WMI commands and queries require a buffer size larger than 128 bytes hence limiting current and feature supported by the driver. It is for this reason, struct bios_args.data changed and is dynamically allocated. hp_wmi_perform_query function changed to handle the memory allocation and release of any required buffer size. All changes were validated on a HP ZBook Workstation notebook, HP EliteBook x360, and HP EliteBook 850 G8. Additional validation was included in the test process to ensure no other commands were incorrectly handled.

2022-03-15nvmet: move the call to nvmet_ns_changed out of nvmet_ns_revalidateChristoph Hellwig
nvmet_ns_changed states via lockdep that the ns->subsys->lock must be held. The only caller of nvmet_ns_changed which does not acquire that lock is nvmet_ns_revalidate. nvmet_ns_revalidate has 3 callers, of which 2 do not acquire that lock: nvmet_execute_identify_cns_cs_ns and nvmet_execute_identify_ns. The other caller nvmet_ns_revalidate_size_store does acquire the lock. Move the call to nvmet_ns_changed from nvmet_ns_revalidate to the callers so that they can perform the correct locking as needed. This issue was found using a static type-based analyser and manually verified.

2022-03-15x86/Kconfig: Do not allow CONFIG_X86_X32_ABI=y with llvm-objcopyNathan Chancellor
There are two outstanding issues with CONFIG_X86_X32_ABI and llvm-objcopy, with similar root causes: 1. llvm-objcopy does not properly convert .note.gnu.property when going from x86_64 to x86_x32, resulting in a corrupted section when linking: https://github.com/ClangBuiltLinux/linux/issues/1141 2. llvm-objcopy produces corrupted compressed debug sections when going from x86_64 to x86_x32, also resulting in an error when linking: https://github.com/ClangBuiltLinux/linux/issues/514 After commit 41c5ef31ad71 ("x86/ibt: Base IBT bits"), the .note.gnu.property section is always generated when CONFIG_X86_KERNEL_IBT is enabled, which causes the first issue to become visible with an allmodconfig build: ld.lld: error: arch/x86/entry/vdso/vclock_gettime-x32.o:(.note.gnu.property+0x1c): program property is too short To avoid this error, do not allow CONFIG_X86_X32_ABI to be selected when using llvm-objcopy. If the two issues ever get fixed in llvm-objcopy, this can be turned into a feature check.

2022-03-15x86: Remove toolchain check for X32 ABI capabilityMasahiro Yamada
Commit 0bf6276392e9 ("x32: Warn and disable rather than error if binutils too old") added a small test in arch/x86/Makefile because binutils 2.22 or newer is needed to properly support elf32-x86-64. This check is no longer necessary, as the minimum supported version of binutils is 2.23, which is enforced at configuration time with scripts/min-tool-version.sh. Remove this check and replace all uses of CONFIG_X86_X32 with CONFIG_X86_X32_ABI, as two symbols are no longer necessary. [nathan: Rebase, fix up a few places where CONFIG_X86_X32 was still used, and simplify commit message to satisfy -tip requirements] Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Signed-off-by: Nathan Chancellor <nathan@kernel.org> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lore.kernel.org/r/20220314194842.3452-2-nathan@kernel.org
2022-03-15x86/alternative: Use .ibt_endbr_seal to seal indirect callsPeter Zijlstra
Objtool's --ibt option generates .ibt_endbr_seal which lists superfluous ENDBR instructions. That is those instructions for which the function is never indirectly called. Overwrite these ENDBR instructions with a NOP4 such that these function can never be indirect called, reducing the number of viable ENDBR targets in the kernel.

2022-03-15objtool: Find unused ENDBR instructionsPeter Zijlstra
Find all ENDBR instructions which are never referenced and stick them in a section such that the kernel can poison them, sealing the functions from ever being an indirect call target. This removes about 1-in-4 ENDBR instructions.

2022-03-15objtool: Validate IBT assumptionsPeter Zijlstra
Intel IBT requires that every indirect JMP/CALL targets an ENDBR instructions, failing this #CP happens and we die. Similarly, all exception entries should be ENDBR. Find all code relocations and ensure they're either an ENDBR instruction or ANNOTATE_NOENDBR. For the exceptions look for UNWIND_HINT_IRET_REGS at sym+0 not being ENDBR.
