The libedit "fout" output must be sent to fd 2 since it contains prompts
that POSIX says must be sent to fd 2. However, the libedit "ferr" output
receives error messages such as from "bind" that make no sense to send to fd
1.
Since r287197 ieee80211com is a part of drivers softc; as a result,
after detach all pointers to it (iv_ic, ni_ic) are invalid. Most
possible users (tasks, interrupt handlers) are blocked / removed
when device is stopped; however, ioctl handlers were not tracked
and may crash if ieee80211com structure is accessed.
Since ieee80211com pointer access from ieee80211vap structure is not
protected by lock (constant after interface creation) and used in
many other places just use reference counting for ioctl handlers;
on detach set 'detached' flag and wait until reference counter goes to 0.
For HEAD ieee80211vap size was changed (__FreeBSD_version bumped);
however, in stable branches I'm going to split / reuse the last
iv_spare field for KBI stability.
Tested with:
- rsu(4), SIOCSIFCAP (-rxcsum) ioctl;
- rtwn_pci(4), SIOCG80211 / IEEE80211_IOC_HTPROTMODE ioctl.

For most wireless drivers Rx mbuf is allocated as one
contiguous chunk; only few are using chains for allocations -
but even then at least MCLBYTES (minus Rx descriptor size) is
available in the first mbuf.
In addition to the above, m_pullup was never called here - otherwise,
reallocation will break post-crypto_decap logic (ieee80211_decap,
ieee80211_deliver_data...), so just remove it; length check is left
in case if some truncated frame appears here.

Book-E powerpc uses 64-bit vm_paddr_t, and 32-bit powerpc has 32-bit pointers,
so gcc errors with cast to pointer from integer of different size. As this will

For parity with Intel hosts, which already mask out the CPUID feature
bits that indicate the presence of the SPEC_CTRL MSR, do the same on
AMD.
Eventually we may want to have a better support story for guests, but
for now, limit the damage of incorrectly indicating an MSR we do not yet
support.
Eventually, we may want a generic CPUID override system for
administrators, or for minimum supported feature set in heterogenous
environments with failover. That is a much larger scope effort than
this bug fix.

Right now bus_addr_t and vm_paddr_t are always aliased to the same
underlying integer type on x86, which makes the interchange hard to
detect. Shortly, i386 kernel would use uint64_t for vm_paddr_t to
enable automatic use of PAE paging structures if hardware allows it,
while bus_addr_t would be extended to 64bit only when PAE option is
specified.
Fix all places that were identified as using bus_addr_t while page
address was assumed. This was performed by testing the complete PAE
merging patch on machine with > 4G of RAM enabled.

In order to allow single kernel to use PAE pagetables on i386 if
hardware supports it, and fall back to classic two-level paging
structures if not, superpage code should be able to adopt to either 2M
or 4M superpages size. There I make MI VM structures large enough to
track the biggest possible superpage, by allowing architecture to
define VM_NFREEORDER_MAX and VM_LEVEL_0_ORDER_MAX constants.
Corresponding VM_NFREEORDER and VM_LEVEL_0_ORDER symbols can be
defined as runtime values and must be less than the _MAX constants.
If architecture does not define _MAXs, it is assumed that _MAX ==
normal constant.

Even M_WAITOK callers must check for failure. For example, if the device is
quiescing, either due to automatic error-recovery induced reset, or due to
administrative detach, the routine will return ENXIO and the acquire
reference will not be held. So, there is no mode in which it is safe to
assume the routine succeeds without checking.
