      SOC_FOO to ARCH_FOO conversion for RISC-V
      
      RISC-V is an outlier in using SOC_FOO rather than ARCH_FOO for
      vendors/micro-archs. SOC_FOO may make more sense (I personally prefer
      it), but the rest of the "world" uses ARCH_FOO. That'd be fine, with
      with an increasing number of existing SoC vendors moving to RISC-V,
      unifying our symbol names with the expectations of the rest of the world
      makes sense.
      Folks did not seem keen on changing the world (and they can't really be
      blamed for that) so convert RISC-V over to match.
      
      Add some ARCH_FOO stubs alongside the existing SOC_FOO ones, which will
      be removed once all users of SOC_FOO have been converted*, and convert
      the DT bits of RISC-V kbuild over to the new symbols.
      
      * It may be best to wait until after the next LTS to remove the SOC_FOO
        ones, for the sake of external users.

      treewide: Convert del_timer*() to timer_shutdown*() · 292a089d
      Steven Rostedt (Google) authored
      Due to several bugs caused by timers being re-armed after they are
      shutdown and just before they are freed, a new state of timers was added
      called "shutdown".  After a timer is set to this state, then it can no
      longer be re-armed.
      
      The following script was run to find all the trivial locations where
      del_timer() or del_timer_sync() is called in the same function that the
      object holding the timer is freed.  It also ignores any locations where
      the timer->function is modified between the del_timer*() and the free(),
      as that is not considered a "trivial" case.
      
      This was created by using a coccinelle script and the following
      commands:
      
          $ cat timer.cocci
          @@
          expression ptr, slab;
          identifier timer, rfield;
          @@
          (
          -       del_timer(&ptr->timer);
          +       timer_shutdown(&ptr->timer);
          |
          -       del_timer_sync(&ptr->timer);
          +       timer_shutdown_sync(&ptr->timer);
          )
            ... when strict
                when != ptr->timer
          (
                  kfree_rcu(ptr, rfield);
          |
                  kmem_cache_free(slab, ptr);
          |
                  kfree(ptr);
          )

      pstore: Properly assign mem_type property · beca3e31
      Luca Stefani authored
      If mem-type is specified in the device tree
      it would end up overriding the record_size
      field instead of populating mem_type.
      
      As record_size is currently parsed after the
      improper assignment with default size 0 it
      continued to work as expected regardless of the
      value found in the device tree.
      
      Simply changing the target field of the struct
      is enough to get mem-type working as expected.

      pstore: Make sure CONFIG_PSTORE_PMSG selects CONFIG_RT_MUTEXES · 2f4fec59
      John Stultz authored
      In commit 76d62f24 ("pstore: Switch pmsg_lock to an rt_mutex
      to avoid priority inversion") I changed a lock to an rt_mutex.
      
      However, its possible that CONFIG_RT_MUTEXES is not enabled,
      which then results in a build failure, as the 0day bot detected:
        https://lore.kernel.org/linux-mm/202212211244.TwzWZD3H-lkp@intel.com/
      
      Thus this patch changes CONFIG_PSTORE_PMSG to select
      CONFIG_RT_MUTEXES, which ensures the build will not fail.

      do_ctors calls the affected constructors:
      
        CFI failure at do_basic_setup+0x64/0x90 (target:
        asan.module_ctor+0x0/0x28; expected type: 0xa540670c)
      
      Specifically, this happens because CFI is disabled for
      kernel/cfi.c. There's no reason to keep CFI disabled here anymore, so
      fix the failure by not filtering out CC_FLAGS_CFI for the file.
      
      Note that https://reviews.llvm.org/rG3b14862f0a96 fixed the issue
      where LLVM didn't emit CFI type hashes for any sanitizer constructors,
      but now type hashes are emitted correctly for TUs that use CFI.
