My builds are still running, but just an initial report for gcc-12. (I know v5.15.y still does not build completely with gcc-12).
x86_64 and arm64 allmodconfig build fails with gcc-12, with the error:
drivers/acpi/thermal.c: In function 'acpi_thermal_resume': drivers/acpi/thermal.c:1101:21: error: the comparison will always evaluate as 'true' for the address of 'active' will never be NULL [-Werror=address] 1101 | if (!(&tz->trips.active[i])) | ^ drivers/acpi/thermal.c:151:36: note: 'active' declared here 151 | struct acpi_thermal_active active[ACPI_THERMAL_MAX_ACTIVE];
Will need e5b5d25444e9 ("ACPI: thermal: drop an always true check").
powerpc allmodconfig fails with gcc-12, the error is:

Introduced in v5.15.61 due to 2711bedab26c ("Bluetooth: L2CAP: Fix l2cap_global_chan_by_psm regression"). But v5.19.y and mainline does not show the build failure as they also have 41b7a347bf14 ("powerpc: Book3S 64-bit outline-only KASAN support").
