8ad85ff260 The doreti_iret_fault code is always called with gs base MSR containing
kernel gs base, because %rip is adjusted only on kernel-mode trap caused
by iretq execution. On the other hand, the stack contains (hardware
part of) trap frame from the usermode. As a consequence, checking for
frame mode and doing swapgs causes the kernel to enter trap() with
usermode gs base.

Remove the check for mode and conditional swapgs, we already have right
gs base in the MSR.

603724d3ab Commit step 1 of the vimage project, (network stack)
virtualization work done by Marko Zec (zec@).

This is the first in a series of commits over the course
of the next few weeks.

Mark all uses of global variables to be virtualized
with a V_ prefix.
Use macros to map them back to their global names for
now, so this is a NOP change only.

We hope to have caught at least 85-90% of what is needed
so we do not invalidate a lot of outstanding patches again.

abf07f13fd Add some sysctl reporting for most pci_pci bridges. We now report
domain, pribus (the primary bus, eg the bus that this chip is on),
secbus (the secondary bus, eg the bus immediately behind this chip)
and subbus (the number of the highest bus behind this chip).
Normally, this information is reported via bootverbose parameters, but
that's hard to use for debugging in some cases.

This adds reading of pribus to make this happen.  In addition, change
the narrow types to u_int to allow for easier reporting via sysctl for
domain, secbus and subbus.  This should have no effect, but if it
does, please let me know.

48d48eb980 Fix a regression introduced in r179289 splitting up ip6_savecontrol()
into v4-only vs. v6-only inp_flags processing.
When ip6_savecontrol_v4() is called from ip6_savecontrol() we
were not passing back the **mp thus the information will be missing
in userland.
Istead of going with a *** as suggested in the PR we are returning
**mp now and passing in the v4only flag as a pointer argument.

2e37c8eacb Convert the snp(4) driver to use cdevpriv.
Now we have a single /dev/snp device node, which can be opened by
watch(8) multiple times. Even though snp(4) will be dead as of next
week, it's nice having this in SVN, because:

- We may want to MFC it to RELENG_7.
- By the time we fix snp(4) again, it's already there, existing watch(8)
  binaries should already work.

Just like bpf(4), I'm adding a symlink from snp0 to snp to remain binary
compatible.
