H A DALL1.503 Sat Sep 24 11:05:17 GMT 2022 riastradh branches: 1.503.4;
x86: Support EFI runtime services.

This creates a special pmap, efi_runtime_pmap, which avoids setting
PTE_U but allows mappings to lie in what would normally be user VM --
this way we don't fall afoul of SMAP/SMEP when executing EFI runtime
services from CPL 0. SVS does not apply to the EFI runtime pmap.

The mechanism is intended to work with either physical addressing or
virtual addressing; currently the bootloader does physical addressing
but in principle it could be modified to do virtual addressing
instead, if it allocated virtual pages, assigned them in the memory
map, and issued RT->SetVirtualAddressMap.

Not sure pmap_activate_sync and pmap_deactivate_sync are correct,
need more review from an x86 wizard.

If this causes fallout, it can be disabled temporarily without
reverting anything by just making efi_runtime_init return immediately
without doing anything, or by removing options EFI_RUNTIME.

amd64-only for now pending type fixes and testing on i386.

valid "mnt_transinfo" and remove now unneeded flag IMNT_HAS_TRANS.

Run fstrans_start()/fstrans_done() on dead_rootmount if FSTRANS_DEAD_ENABLED.
Should become the default for DIAGNOSTIC in the future.

H A Dif.c1.503 Sat Apr 09 23:38:33 GMT 2022 riastradh sys: Use membar_release/acquire around reference drop.

This just goes through my recent reference count membar audit and
changes membar_exit to membar_release and membar_enter to
membar_acquire -- this should make everything cheaper on most CPUs
without hurting correctness, because membar_acquire is generally
cheaper than membar_enter.

H A Djob.c1.503 Fri May 09 20:26:03 GMT 2025 rillig make: error out if writing to an internal pipe fails

The write end of the childExitJob pipe is synchronous, therefore, there
is no EAGAIN to be expected. Writing to the pipe is expected to succeed,
so error out noticeably.
