750eb154f1 Fix an inverted test csae. Success of getenv() is determined by a return 
value of !NUL rather than NUL.

3b0708baaa Use %ecx instead of %ebx for the scratch register while updating %dr7 since 
%ecx isn't a call safe register and thus we don't have to save and restore
it.

655d637879 - Fix typo in comment from previous revision. 
- Fix a bug in the LDT changes where the wrong argument was passed to
  set_user_ldt() from cpu_switch().  The bug was passing a pointer to the
  ldt, but set_user_ldt() takes a pointer to the process' mdproc structure.

3ae1b5c128 Fixed bugs in rev.1.973. Actually enable PCI_ENABLE_IO_MODES. It 
defeats the point of LINT to comment out positive options.

Fixed style bugs in rev.1.973:
- disordering of PCI options list.
- missing space after "options".
- line longer than 80 characters.
- bogus quoting of "BIOS".

67beb4eaf7 Add support for loadable microcode which implements interrupt coalescing 
and packet bundling.  Make the microcode settings controllable via sysctl
and loader tunables.

Submitted by: Marko Zec <zec@tel.fer.hr>

Also extend the workaround for Dynamic Standby mode to later '559 chips,
not just the ICH2 variants.

c0bfb6b8ea If we get an unhandled page fault in kernel mode, either panic (if 
pcb_onfault is not set) or arrange to restart at the location in
pcb_onfault.

This ought to help the stability of a system under moderate load. It
certainly stops DDB from hanging the kernel when it tries to access a
non-present page.

  at the type in the trapframe.

1704b54dc9 o Note an additional potential problem here: LOCKD_MSG directly exports 
struct ucred to userland.  In 5.0-CURRENT, it is desirable to instead
  export struct xucred, as ucred contains mutexes, pointers, and other
  kernel evil.  I'll add it to my work queue.
