IIUC, fchmodat2(fd, "", m, AT_EMPTY_PATH) is equivalent to fchmod(fd,
m). With that, new architectures only need to implement the fchmodat2

It breaks suspend.

If STRICT_KERNEL_RWX is disabled, never use the MMU to mark initmen
nonexecutable.
Also move a misplaced paren that makes the condition always true.

That is always true.
And
This breaks suspend (or resume) on the iBook G4. no_console_suspend
doesn't give any clues, the display just stays dark.

None of the format directives match the type of the arguments.

Alternatively, the return type could be changed to bool, so that the
compiler does the right thing by itself.

I think the right fix is to change nowtime in pmu_set_rtc_time and
cuda_set_rtc_time back to unsigned int (or to u32).

Then why are PMU_68K_V1 and PMU_68K_V2 defined in the first place?

It also changes the value of PMU_68K_V2, which is an ABI break.

This is not a valid use of IPC_STAT. The fourth argument must be a
object of type union semun (not a pointer), with the .buf member
pointing to the struct semid_ds object.

I think these messages are harmless and expected. This device has no
x86 option ROM but a OpenFirmware one. This is likely unrelated to the
sddm crash.
