Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into staging

* Log filtering from Alex and Peter
* Chardev fix from Marc-André
* config.status tweak from David
* Header file tweaks from Markus, myself and Veronia (Outreachy candidate)
* get_ticks_per_sec() removal from Rutuja (Outreachy candidate)
* Coverity fix from myself
* PKE implementation from myself, based on rth's XSAVE support

* remotes/bonzini/tags/for-upstream: (28 commits)
  target-i386: implement PKE for TCG
  config.status: Pass extra parameters
  char: translate from QIOChannel error to errno
  exec: fix error handling in file_ram_alloc
  cputlb: modernise the debug support
  qemu-log: support simple pid substitution for logs
  target-arm: dfilter support for in_asm
  qemu-log: dfilter-ise exec, out_asm, op and opt_op
  qemu-log: new option -dfilter to limit output
  qemu-log: Improve the "exec" TB execution logging
  qemu-log: Avoid function call for disabled qemu_log_mask logging
  qemu-log: correct help text for -d cpu
  tcg: pass down TranslationBlock to tcg_code_gen
  util: move declarations out of qemu-common.h
  Replaced get_tick_per_sec() by NANOSECONDS_PER_SECOND
  hw: explicitly include qemu-common.h and cpu.h
  include/crypto: Include qapi-types.h or qemu/bswap.h instead of qemu-common.h
  isa: Move DMA_transfer_handler from qemu-common.h to hw/isa/isa.h
  Move ParallelIOArg from qemu-common.h to sysemu/char.h
  Move QEMU_ALIGN_*() from qemu-common.h to qemu/osdep.h
  ...
