When we encounter an I/O error on a piece of metadata while deleting
a file system or zvol, we don't update the bptree_entry_phys_t's
bookmark. This would lead to double free of bp's which will lead to
space map corruption.
Instead of tolerating and allowing the corruption, panic immediately.
See Illumos #4390 for more details.

The operation was documented and implemented partially (both from a
type and architecture perspective) on 2013-08-21 and got used in
ZFS with revision 260150 (zfeature.c) and since ZFS is supported on
ia64, the lack of having atomic_swap became problem.
- Use simple ++ for rare events.
- Use uma_zone_get_cur() to get knowledge about space left in cache.
- Convert many fields of struct ng_netflow_info to 64 bit.

to enter guest context and vmx_exit_guest() is used to transition back into
host context.
Fix a longstanding race where a vcpu interrupt notification might be ignored
if it happens after vmx_inject_interrupts() but before host interrupts are
disabled in vmx_resume/vmx_launch. We now called vmx_inject_interrupts() with
host interrupts disabled to prevent this.

FreeBSD porting notes: the kernel part of this changeset depends
on Solaris buf(9S) interfaces and are not really applicable for

no longer any need for the page's PG_CACHED and PG_FREE flags to be set and
cleared while the free page queues lock is held. Thus, vm_page_alloc(),
vm_page_alloc_contig(), and vm_page_alloc_freelist() can wait until after
the free page queues lock is released to clear the page's flags. Moreover,
the PG_FREE flag can be retired. Now that the reservation system no longer
uses it, its only uses are in a few assertions. Eliminating these
assertions is no real loss. Other assertions catch the same types of
misbehavior, like doubly freeing a page (see r260032) or dirtying a free
page (free pages are invalid and only valid pages can be dirtied).
Eliminate an unneeded variable from vm_page_alloc_contig().
