Pull powerpc fixes from Michael Ellerman:
 "It's a bit of a big batch for rc6, but just because I didn't send any
  fixes the last week or two while I was on vacation, next week should
  be quieter:

   - Fix a few objtool warnings since we recently enabled objtool.

   - Fix a deadlock with the hash MMU vs perf record.

   - Fix perf profiling of asynchronous interrupt handlers.

   - Revert the IMC PMU nest_init_lock to being a mutex.

   - Two commits fixing problems with the kexec_file FDT size
     estimation.

   - Two commits fixing problems with strict RWX vs kernels running at
     non-zero.

   - Reconnect tlb_flush() to hash__tlb_flush()

  Thanks to Kajol Jain, Nicholas Piggin, Sachin Sant Sathvika Vasireddy,

Pull ARM SoC fixes from Arnd Bergmann:
 "The majority of bugfixes is once more for the NXP i.MX platform,
  addressing issue with i.MX8M (UART, watchdog and ethernet) as well as
  imx8dxl power button and the USB modem on an imx7 board.

  The reason that i.MX always shows up here is obviously not that they
  are more buggy than the others, but they have the most boards and are
  good about getting fixes in quickly.

  The other DT fixes are for the Nuvoton wpcm450 flash controller and
  the i2c mux on an ASpeed board.

  Lastly, there are updates to the MAINTAINERS entries for Mediatek,
  AMD/Seattle and NXP SoCs, as well as a lone code fix for error
  handling in the allwinner 'rsb' bus driver"

Pull s390 fixes from Heiko Carstens:

 - With CONFIG_VMAP_STACK enabled it is not possible to load the s390
   specific diag288_wdt watchdog module. The reason is that a pointer to
   a string is passed to an inline assembly; this string however is
   located on the stack, while the instruction within the inline
   assembly expects a physicial address. Fix this by copying the string
   to a kmalloc'ed buffer.

 - The diag288_wdt watchdog module does not indicate that it accesses
   memory from an inline assembly, which it does. Add "memory" to the
   clobber list to prevent the compiler from optimizing code incorrectly
   away.

 - Pass size of the uncompressed kernel image to __decompress() call.
   Otherwise the kernel image decompressor may corrupt/overwrite an
   initrd. This was reported to happen on s390 after commit 2aa14b1ab2c4
   ("zstd: import usptream v1.5.2").

* tag 's390-6.2-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390/decompressor: specify __decompress() buf len to avoid overflow
  watchdog: diag288_wdt: fix __diag288() inline assembly
  watchdog: diag288_wdt: do not use stack buffers for hardware data

GCC 13 will enable -fasynchronous-unwind-tables by default on riscv.  In
the kernel, we don't have any use for unwind tables yet, so disable them.
More importantly, the .eh_frame section brings relocations
(R_RISC_32_PCREL, R_RISCV_SET{6,8,16}, R_RISCV_SUB{6,8,16}) into modules
that we are not prepared to handle.
