ac5774c288 Fix a 64-bit pointer/int warning. 1998-03-19 03:42:35 +00:00

003c50d1d5 Add a macro to invalidate the TLB for a given pmap/va pair. TLB 
invalidation algorithm:

	if (old mapping had PG_ASM set || pmap is active) {
		TIBS(va);
		if (also sync I-stream)
			imb();
	}

The check for "old mapping had PG_ASM" will get all kernel mappings (since
kernel mappings always have PG_ASM set).

This allows us to remove the bogus check for the kernel pmap in
active_pmap() - do so.

Use the new TLB invalidation macro whenever such action is needed.

15adb17803 Eliminate the last argument from pmap_remove_mapping(); it makes its own

7ee4af11a7 Change active_pmap() to use the CPU mask (XXX and check for kernel pmap 
as well, until some other changes are made).  Nuke active_user_pmap(),
and change the places that used it to use active_pmap() instead (as well
as make some DIAGNOSTIC consistency checks).

605472f676 Optimize out a TLB invalidation in a common case of pmap_enter(): if 
the PTE was previously invalid, no TLB invalidation is necessary because:

	(1) when a PTE is invalidated, its entry is flushed from the
	    TLB

	(2) the PALcode won't install an invalid PTE into the TLB.

091dafd39f Add support for reading/writing FFS in non-native byte order, conditioned 
to "options FFS_EI". The superblock and inodes (without blk addr) are
byteswapped at disk read/write time, other metadatas are byteswapped
when used (as they are acceeded directly in the buffer cache).
This required the addition of a "um_flags" field to struct ufsmount.
ffs_bswap.c contains superblock and inode byteswap routines also used
by userland utilities.

86d534a7d9 - Make MACHINE_NEW_NONCONTIG non-optional. 
- Maintain two copies of the number and size of physical memory segments.
  One copy, mem_clusters[], contains _all_ of physical RAM, for crash dumps.
  The other copy, phys_seg_list[], starts out with all of physical RAM (and
  is used to initialize mem_clusters[]), but is adjusted to be the memory
  actually managed by the VM system.
- Fix computation of physmem; when support for MACHINE_NEW_NONCONTIG was
  added, physmem was accidentally changed to not take into account the memory
  located before the kernel, or the memory taken up by the kernel itself.

efbd14c45d mounting a union causes VOP_WHITEOUT to be called on the upper root 
vn, with a 0 component.  If the upper fs was a unionfs,
union_whiteout() would deref compnent to get a struct proc, and panic.
struct proc was only being passed to FIXUP, which never used it.  It
turns out this happened a lot.  I ripped most of the unneeded code
out, and left in the few places that really did need the proc handle.

b9eaff9db8 when considering attaching compatibility-mode channels, try a quick reset 
and see if anything responds.  if nothing (that's attributable to the
PCI IDE controller) responds, then that channel either has no devices on
it or has been disabled (via a non-standard mechanism) by the BIOS.  If nothing
responds, don't map the compat.-mode interrupt or attach the wdc to that
channel, because the BIOS is likely to assign that IRQ to a different PCI
device.  If that happens, the kernel will panic because that device will
try to map the IRQ level-triggered, but the compat interrupt will have been
mapped edge-triggered.  (One possible way around this is to map the compat
interrupt edge-triggered, but it's not clear reading the spec that this
is correct or desirable.)

ff06be8ce0 reorganize mapping/attachment of wdc channels so that it'll be easier to 
insert a check to see whether a channel appears to be enabled.  Shouldn't
be necessary, according to the spec, but some PC chipsets allow individual
compatibility channels to be disabled.  "I hate PCs."

25f48b177c Use NKPDE page table pages (instead of only one) for temporary mapping 
in transition to relocated mode.
Remove preparation for "bioscall" identity mapping - it is in the way
and can be done later in init386().
Should solve the problem described in PR 4832 and 5102.

84c6b9dbd7 Make zs_iflush not loop indefinitly. Some Mac PowerBooks lie about having 
two SCC channels, and can get stuck in an infinite loop. This change
stops after flushing 4 bytes. Might need upping to 8 bytes if we support
85230 ESCC's.
