As we provide the disk size verification and correction via disk_ioctl
and disk state provided by disk_open(), we can not share the partition
state in disk_devdesc structure. Also the sharing does make a lot of sense
with ufs, as only one partition is open at any given time, but zfs pools
do keep the disk devices open.
To make sure we do get the correct information about the open device,
just remove the cache.

Fix this by using more dynamic initialization with simpler ifdefs for
the machine dependencies. Find a frame buffer address in a more
portable way that at least compiles on sparc64.
Otherwise, recent Linux guests will use these instructions, resulting
in #UD exceptions since bhyve doesn't implement MONITOR/MWAIT exits.
This fixes boot-time hangs in recent Linux guests on Ryzen CPUs
(and probably Bulldozer aka AMD FX as well).

The boot1.efi immediate issue from PR216964 is that we are reading into
too small buffer, from UEFI spec 2.6:
The size of the Buffer in bytes. This must be a multiple of the intrinsic block size of the device.
The secondary issue is that LBA calculation does not check reminder from
division.
This fix does check the provided buffer size and if we read less than
media sector size or the read offset is not aligned to sector boundary,
we allocate bounce buffer and perform the read by single sector.

uma_zcreate()'s alignment argument is supposed to be sizeof(foo) - 1,
and uma.h provides a set of helper macros for common types. Passing
sizeof(void *) results in all of the members being misaligned triggering
unaligned access faults on certain architectures (notably MIPS).

Instead of single isp_intr() function doing all possible magic, introduce
four different functions to handle mailbox operation completions, async
events, response and ATIO queues. The goal is to isolate different code
paths to make code more readable, and to make easier support for multiple
interrupt vectors. Even oldest hardware in many cases can identify what
code path it should run on interrupt. Contemporary hardware can assign
them to different interrupt vectors.

POSIX 2008 says this about clock_settime(2):
If the value of the CLOCK_REALTIME clock is set via clock_settime(),
the new value of the clock shall be used to determine the time
of expiration for absolute time services based upon the
CLOCK_REALTIME clock. This applies to the time at which armed
absolute timers expire. If the absolute time requested at the
invocation of such a time service is before the new value of
the clock, the time service shall expire immediately as if the
clock had reached the requested time normally.
Setting the value of the CLOCK_REALTIME clock via clock_settime()
shall have no effect on threads that are blocked waiting for
a relative time service based upon this clock, including the
nanosleep() function; nor on the expiration of relative timers
based upon this clock. Consequently, these time services shall
expire when the requested relative interval elapses, independently
of the new or old value of the clock.
When the real-time clock is adjusted, such as by clock_settime(3),
wake any threads sleeping until an absolute real-clock time.
Such a sleep is indicated by a non-zero td_rtcgen. The sleep functions
will set that field to zero and return zero to tell the caller
to reevaluate its sleep duration based on the new value of the clock.
At present, this affects the following functions:
pthread_cond_timedwait(3)
pthread_mutex_timedlock(3)
pthread_rwlock_timedrdlock(3)
pthread_rwlock_timedwrlock(3)
sem_timedwait(3)
sem_clockwait_np(3)
I'm working on adding clock_nanosleep(2), which will also be affected.

Keep your brain turned on and engaged when making a tedious, sweeping,
mechanical change. KTR can correctly log the immediate integral values
