2021-10-28docs: submitting-patches: make section about the Link: tag more explicitThorsten Leemhuis1-11/+22
Mention the 'Link' tag in the section about adding URLs to the commit msg, to make it clearer they "_primarily_ [...] should be about background", as Linus recently stated (see the link below). That makes the explanation also easier to find with a text search. For the same reason and to improve comprehensibility provide an example, too. Slightly improve the text at the same time to make it more obvious developers are meant to add links to issue reports in mailing list archives, as those allow regression tracking efforts to automatically check which bugs got resolved. Move the section also downwards slightly, to reduce jumping back and forth between aspects relevant for the top and the bottom part of the commit msg.

There's a warning there from a .gitignore file: tools/perf/.gitignore: Documentation/doc.dep This is not really a cross-reference type of warning, so no need to report it.

In commit b212921b13bd ("elf: don't use MAP_FIXED_NOREPLACE for elf executable mappings") we still leave MAP_FIXED_NOREPLACE in place for load_elf_interp. Unfortunately, this will cause kernel to fail to start with: 1 (init): Uhuuh, elf segment at 00003ffff7ffd000 requested but the memory is mapped already Failed to execute /init (error -17) The reason is that the elf interpreter (ld.so) has overlapping segments. readelf -l ld-2.31.so Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align LOAD 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x000000000002c94c 0x000000000002c94c R E 0x10000 LOAD 0x000000000002dae0 0x000000000003dae0 0x000000000003dae0 0x00000000000021e8 0x0000000000002320 RW 0x10000 LOAD 0x000000000002fe00 0x000000000003fe00 0x000000000003fe00 0x00000000000011ac 0x0000000000001328 RW 0x10000 The reason for this problem is the same as described in commit ad55eac74f20 ("elf: enforce MAP_FIXED on overlaying elf segments"). Not only executable binaries, elf interpreters (e.g. ld.so) can have overlapping elf segments, so we better drop MAP_FIXED_NOREPLACE and go back to MAP_FIXED in load_elf_interp.

2021-10-03objtool: print out the symbol type when complaining about itLinus Torvalds1-4/+8
The objtool warning that the kvm instruction emulation code triggered wasn't very useful: arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception in that it helpfully tells you which symbol name it had trouble figuring out the relocation for, but it doesn't actually say what the unknown symbol type was that triggered it all. In this case it was because of missing type information (type 0, aka STT_NOTYPE), but on the whole it really should just have printed that out as part of the message. Because if this warning triggers, that's very much the first thing you want to know - why did reloc2sec_off() return failure for that symbol? So rather than just saying you can't handle some type of symbol without saying what the type _was_, just print out the type number too.

2021-10-03kvm: fix objtool relocation warningLinus Torvalds1-1/+0
The recent change to make objtool aware of more symbol relocation types (commit 24ff65257375: "objtool: Teach get_alt_entry() about more relocation types") also added another check, and resulted in this objtool warning when building kvm on x86: arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception The reason seems to be that kvm_fastop_exception() is marked as a global symbol, which causes the relocation to ke kept around for objtool. And at the same time, the kvm_fastop_exception definition (which is done as an inline asm statement) doesn't actually set the type of the global, which then makes objtool unhappy. The minimal fix is to just not mark kvm_fastop_exception as being a global symbol. It's only used in that one compilation unit anyway, so it was always pointless. That's how all the other local exception table labels are done. I'm not entirely happy about the kinds of games that the kvm code plays with doing its own exception handling, and the fact that it confused objtool is most definitely a symptom of the code being a bit too subtle and ad-hoc. But at least this trivial one-liner makes objtool no longer upset about what is going on.

2021-10-02cachefiles: Fix oops in trace_cachefiles_mark_buried due to NULL objectDave Wysochanski1-1/+1
In cachefiles_mark_object_buried, the dentry in question may not have an owner, and thus our cachefiles_object pointer may be NULL when calling the tracepoint, in which case we will also not have a valid debug_id to print in the tracepoint. Check for NULL object in the tracepoint and if so, just set debug_id to MAX_UINT as was done in 2908f5e101e3 ("fscache: Add a cookie debug ID and use that in traces"). This fixes the following oops: FS-Cache: Cache "mycache" added (type cachefiles) CacheFiles: File cache on vdc registered ...

2021-10-02drm/i915: fix blank screen booting crashesHugh Dickins1-2/+3
5.15-rc1 crashes with blank screen when booting up on two ThinkPads using i915. Bisections converge convincingly, but arrive at different and suprising "culprits", none of them the actual culprit. netconsole (with init_netconsole() hacked to call i915_init() when logging has started, instead of by module_init()) tells the story: kernel BUG at drivers/gpu/drm/i915/i915_sw_fence.c:245! with RSI: ffffffff814d408b pointing to sw_fence_dummy_notify(). I've been building with CONFIG_CC_OPTIMIZE_FOR_SIZE=y, and that function needs to be 4-byte aligned.

The Rainier power supply returns the bytes in LSB/MSB order. The Witherspoon power supply uses version cffps1. The Rainier power supply should use version cffps2.

Because Rui is now going to focus on work that is not related to the maintenance of the thermal subsystem in the kernel, Rafael will start to help Daniel with handling the development process as a new member of the thermal maintainers team. Rui will continue to review patches in that area. The thermal development process flow will change so that the material from the thermal git tree will be merged into the thermal branch of the linux-pm.git tree before going into the mainline. Update the information in MAINTAINERS accordingly. Signed-off-by: Rafael J.
