The EFI framebuffer produces corrupted output on certain systems. For
now display the framebuffer parameters (address, dimensions, etc.) on
boot to aid in tracking down these issues.

Mark cpu_search_lowest/cpu_search_highest/cpu_search_both as noinline,
while cpu_search() gets always_inline. With the attributes set,
cpu_search() is inlined in wrappers, and if()s with constant
conditionals are optimized.
On some tests on many-core machine, the hwpmc reported samples for
cpu_search*() are reduced from 25% total to 9%.

- Don't discard frames if the dropped or error flag is set.
- Don't remove the last 4-bytes of every packet.
- Add extra range check for data position offset when receiving data.

The array index for the callchain is getting double-incremented -- both in the
loop and the storing. It should only be incremented in one location.
Also, constrain the stack pointer range check.

requests on the trim_queue, even for the CFA ERASE. This allows us, in
the future, to collapse adjacent requests. Since CFA ERASE is only for
CF cards, and it is so restrictive in what it can do, the collapse
code is not presently here. This also brings the ada driver more in
line with the da driver's treatment of BIO_DELETEs.

UPDATING. This is the first step towards the removal of ia64 from
head. A buildworld for ia64 will now yield:
% make buildworld
make[1]: "/usr/src/Makefile.inc1" line 151: Unknown target ia64:ia64.
While here, trim the ia64-specific additions from ObsoleteFiles.inc
Discussed at: BSDcan
descriptors in order to relocate RTLD itself. To allocate memory,
we need the pagesizes array initialized, but that happens after
RTLD is relocated. This ordering is important for amd64, but it's
opposite of what ia64 needs. Handle this conflict with the define
called RTLD_INIT_PAGESIZES_EARLY. When defined, obtain the page
sizes before relocating rtld, otherwise do it after.
Don't check ZVOL_WCE flag, used in Solaris to control device "write cache".
It is not applicable on FreeBSD and by default set to "disable".

As sc(4) and vt(4) coexist and are both enabled in GENERIC, the existence
of a vt(4) sysctl is not sufficient to determine that vt(4) is in use.
Reported by: Trond Endrestøl
Both vt(4) and ofwfb(4) need a lot of love to be usable on sparc64 and even
then the performance of ofwfb(4) would suck compared to hardware accelerated
drivers like creator(4) and machfb(4).
The UEFI framebuffer driver vt_efifb requires vt(4), so add a mechanism
for the startup routine to set the preferred console. This change is
ugly because console init happens very early in the boot, making a
cleaner interface difficult. This change is intended only to facilitate
the sc(4) / vt(4) transition, and can be reverted once vt(4) is the
default.
1. oce_multiq_start(): make sure the buffer is consumed even on ENXIO
2. oce_multiq_transmit(): there is an extra call to drbr_enqueue()
causing the mbuf to be enqueued twice when the NIC's queue is full,
and potential panics
3. oce_multiq_transmit(): same problem fixed recently in ixgbe (r267187)
and other drivers: if the mbuf is enqueued, the proper return value is 0

These have no effect on FreeBSD, in fact they are ifdef'ed,
but make easier future merges:

6718877 crgetzoneid() use can cause problems when forking processes with
USDT providers in a non global zone
