This changes the order of hook processing as the copy-on-write handlers
are called after the journal processing. This makes more sense as the
journal overwrite is logically part of the disk IO.
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:
1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.
2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.
I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.
This man-page is based on OpenBSD's securelevel(7), and the copyright was
not reflecting that (probably due to a copy/paste error on my part; I can't
remember).
Noticed by Jeremy C. Reed, thanks!
- don't use VERBOSE_INIT_ARM
- dont configure obio UART
- using intr -1 for now, causes callout interrupt polling
can use that until serirq from 8712 works
in mmu_init_table\gemini_start.S and devmap[]\gemini_machdep.c;
this allows some flexibility e.g. to map 'em all, which is useful
e.g. when using obio uart to debug lpc uart.
- add mmu_init_table entries for Gemini global regs, lpchc, and lpcio
these are needed to consinit() when console is lpc uart

- add mmu_init_table entries for Gemini global regs, lpchc, and lpcio
these are needed to consinit() when console is lpc uart
- now have 2 versions of consinit, one for obio uart,
the other for lpc uart; we use CONSADDR to determine
which gets compiled.
- remove a useless bus_space map/unmap from obio uart version of consinit
comcnattach() will do his own...
- introduce X11FLAVOUR to choose src/x11 vs src/external/mit/xorg
for the X11 to build if MKX11=yes is set. it takes the values
of either Xorg or XFree86.
- default to Xorg on alpha, i386, macppc, shark, sparc and sparc64
- remove MKXORG_WITH_XSRC_XSERVER, unused and never useful
When a TCP timer is disarmed (with callout_stop()) in the general case
callout_invoking() isn't checked, so the timer handler could be called run
when the current interrupt handler exits, athough the timer is disarmed.
This case cause bad things like TCPT_REXMT and TCPT_PERSIST being both pending,
causing a panic (see the PR for details).
Close the issue by aborting the handler if the timer is not callout_expired().
(the EXPIRED flag being cleared by callout_stop()).
