 1.37  20-Jul-2022  thorpej In the Alpha tc_syncbus(), we need to issue a MB because WMB does not
order reads with respect to writes. Remove now-redundant tc_wmb()
calls before tc_syncbus().

NFC on MIPS other than removing a redundant wbflush() (tc_wmb() followed
by tc_syncbus()).
 1.36  10-Nov-2019  chs in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.
 1.35  04-Nov-2013  christos branches: 1.35.30;
add __USE() for unused volatile variables, so that we generate the same code.
 1.34  13-Mar-2012  elad branches: 1.34.2; 1.34.4;
Replace the remaining KAUTH_GENERIC_ISSUSER authorization calls with
something meaningful. All relevant documentation has been updated or
written.

 1.15  29-Jun-2003  fvdl branches: 1.15.2;
Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
 1.14  29-Jun-2003  simonb Fix 'struct lwp *' lossage.
 1.13  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.

 1.10  17-Mar-2002  atatat Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup

page option might cover that.
