Merge tag 'exec-20241220' of https://github.com/philmd/qemu into staging
Accel & Exec patch queue - Ignore writes to CNTP_CTL_EL0 on HVF ARM (Alexander) - Add '-d invalid_mem' logging option (Zoltan) - Create QOM containers explicitly (Peter) - Rename sysemu/ -> system/ (Philippe) - Re-orderning of include/exec/ headers (Philippe) Move a lot of declarations from these legacy mixed bag headers: . "exec/cpu-all.h" . "exec/cpu-common.h" . "exec/cpu-defs.h" . "exec/exec-all.h" . "exec/translate-all" to these more specific ones: . "exec/page-protection.h" . "exec/translation-block.h" . "user/cpu_loop.h" . "user/guest-host.h" . "user/page-protection.h" # -----BEGIN PGP SIGNATURE----- # # iQIzBAABCAAdFiEE+qvnXhKRciHc/Wuy4+MsLN6twN4FAmdlnyAACgkQ4+MsLN6t # wN6mBw//QFWi7CrU+bb8KMM53kOU9C507tjn99LLGFb5or73/umDsw6eo/b8DHBt # KIwGLgATel42oojKfNKavtAzLK5rOrywpboPDpa3SNeF1onW+99NGJ52LQUqIX6K # A6bS0fPdGG9ZzEuPpbjDXlp++0yhDcdSgZsS42fEsT7Dyj5gzJYlqpqhiXGqpsn8 # 4Y0UMxSL21K3HEexlzw2hsoOBFA3tUm2ujNDhNkt8QASr85yQVLCypABJnuoe/// # 5Ojl5wTBeDwhANET0rhwHK8eIYaNboiM9fHopJYhvyw1bz6yAu9jQwzF/MrL3s/r # xa4OBHBy5mq2hQV9Shcl3UfCQdk/vDaYaWpgzJGX8stgMGYfnfej1SIl8haJIfcl # VMX8/jEFdYbjhO4AeGRYcBzWjEJymkDJZoiSWp2NuEDi6jqIW+7yW1q0Rnlg9lay # ShAqLK5Pv4zUw3t0Jy3qv9KSW8sbs6PQxtzXjk8p97rTf76BJ2pF8sv1tVzmsidP # 9L92Hv5O34IqzBu2oATOUZYJk89YGmTIUSLkpT7asJZpBLwNM2qLp5jO00WVU0Sd # +kAn324guYPkko/TVnjC/AY7CMu55EOtD9NU35k3mUAnxXT9oDUeL4NlYtfgrJx6 # x1Nzr2FkS68+wlPAFKNSSU5lTjsjNaFM0bIJ4LCNtenJVP+SnRo= # =cjz8 # -----END PGP SIGNATURE----- # gpg: Signature made Fri 20 Dec 2024 11:45:20 EST # gpg: using RSA key FAABE75E12917221DCFD6BB2E3E32C2CDEADC0DE # gpg: Good signature from "Philippe Mathieu-Daudé (F4BUG) <f4bug@amsat.org>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: FAAB E75E 1291 7221 DCFD 6BB2 E3E3 2C2C DEAD C0DE * tag 'exec-20241220' of https://github.com/philmd/qemu: (59 commits) util/qemu-timer: fix indentation meson: Do not define CONFIG_DEVICES on user emulation system/accel-ops: Remove unnecessary 'exec/cpu-common.h' header system/numa: Remove unnecessary 'exec/cpu-common.h' header hw/xen: Remove unnecessary 'exec/cpu-common.h' header target/mips: Drop left-over comment about Jazz machine target/mips: Remove tswap() calls in semihosting uhi_fstat_cb() target/xtensa: Remove tswap() calls in semihosting simcall() helper accel/tcg: Un-inline translator_is_same_page() accel/tcg: Include missing 'exec/translation-block.h' header accel/tcg: Move tcg_cflags_has/set() to 'exec/translation-block.h' accel/tcg: Restrict curr_cflags() declaration to 'internal-common.h' qemu/coroutine: Include missing 'qemu/atomic.h' header exec/translation-block: Include missing 'qemu/atomic.h' header accel/tcg: Declare cpu_loop_exit_requested() in 'exec/cpu-common.h' exec/cpu-all: Include 'cpu.h' earlier so MMU_USER_IDX is always defined target/sparc: Move sparc_restore_state_to_opc() to cpu.c target/sparc: Uninline cpu_get_tb_cpu_state() target/loongarch: Declare loongarch_cpu_dump_state() locally user: Move various declarations out of 'exec/exec-all.h' ...
