in XEN2 and XEN3 kernels.
Xen really requires cgd, and as users are likely to get a domain given
to them without the possibility of recompiling a kernel for
themselves, we need to provide this by default.
As discussed with bouyer@, and with his OK.
flags to the compiler so it obeys the same ABI as the rest of the kernel.
Remove the hacks used to work around the abi differences (using %s7 as
curlwp) intruduced for the binary hal.
- remove local shrinked memcpy() from bootxx.c bacause
now it's identical with __OPTIMIZE_SIZE__ libsa one
derived from src/common/lib/libc/string/bcopy.c.
Tested netboot from le0 and bootxx + boot from sd0 on SS1+.
have no drivers.
Standby TIMER that we don't use. One of the timers is always out of
standby on my Jornada on boot (WinCE uses it), so save some power.
Standby AFE and FIR for which we have no drivers (I don't know if any
hpcsh hardware actually uses them, so they are likely to be in standby
already anyway).
Fix numerous problems:
1. LDT updates are not atomic.
2. Number of processes running with private LDTs and/or I/O bitmaps
is not capped. System with high maxprocs can be paniced.
3. LDTR can be leaked over context switch.
4. GDT slot allocations can race, giving the same LDT slot to two procs.
5. Incomplete interrupt/trap frames can be stacked.
6. In some rare cases segment faults are not handled correctly.
some reason. Restore it to correct 16.
HTF did hpcsh work all this time with hd6446x_imask[_IPL_N] indexed
with IPLs 0..15 is a mistery... Discovered by accidentally triggering
hd64461 timer interrupt that is not enabled and should have been
masked.
_IPL_N used to be *also incorrect* 15 before Andy's change, which
makes one wonder if dumb luck is severly underappreciated.
easier to do it there rather than mess with config_interrupts()).
From kiyohara@. Discussed with drochner@, who pointed out that pcmcia
drivers are expected to attach with interrupts enabled.
to memcpy(). Work around that by using a local variable instead.
(This looks a bit dubious, but who am I to judge the restrictions
in the standalone environment on the vax -- this should not change
the semantics of what was here before.)
implementation of bcopy() needs to become memcpy() as well. The
simpler local implementation is needed so that the boot code doesn't
overflow the available space.
registers. if we faulted trying to set them, just fall into
"we_re_toast", and arrange for a SEGV to be delivered to the
userland process. fixes kernel mode faults.
