Rework the dynamic per-CPU stats code a bit. Always set 'statics->ncpus'
to the maximum number of CPUs to ensure that lcpustates[] array is always
allocated to the maximum size. Previously, if top was started without
per-CPU stats it would allocate a smaller lcpustates[] array. When
per-CPU stats were then enabled, it would overflow the array and trash
the cpustates_columns[] array causing the CPU stats to be printed in the
wrong locations.
Fix building of 32-bit compat libraries on amd64 with clang, and using
-g, by reverting r219139. The LLVM PR referenced in that revision was
fixed in the mean time, and we imported a clang snapshot soon
afterwards, so the temporary workaround of disabling clang's integrated
assembler is no longer needed.
In this particular case, using e.g. DEBUG_FLAGS=-g causes clang to
output certain directives into assembly that our version of GNU as
chokes on.
sintrcnt/sintrnames is the address of the size, not the actual size.
Use them appropriately to fetch the actual size.

Fix a LOR between hwpmc and the kernel linker. When a system-wide
sampling mode PMC is allocated, hwpmc calls linker_hwpmc_list_objects()
while already holding an exclusive lock on pmc-sx lock. list_objects()
tries to acquire an exclusive lock on the kld_sx lock. When a KLD module
is loaded or unloaded successfully, kern_kld(un)load calls into the pmc
hook while already holding an exclusive lock on the kld_sx lock. Calling
the pmc hook requires acquiring a shared lock on the pmc-sx lock.
Fix this by only acquiring a shared lock on the kld_sx lock in
linker_hwpmc_list_objects(), and also downgrading to a shared lock on the
kld_sx lock in kern_kld(un)load before calling into the pmc hook. In
kern_kldload this required moving some modifications of the linker_file_t
to happen before calling into the pmc hook.
This fixes the deadlock by ensuring that the hwpmc -> list_objects() case
is always able to proceed. Without this patch, I was able to deadlock a
multicore system within minutes by constantly loading and unloading an KLD
module while I simultaneously started a sampling mode PMC in a loop.

The MBR uses a 32-bit unsigned integer to store the size of a slice, but
fdisk(1) internally uses a signed int. Should a user attempt to specify
a slice containing more than 2^31 - 1 sectors, an error will be reported
on systems with sizeof(long) == 4 and the slice size will be silently
truncated on systems with sizeof(long) > 4.
Instead use an unsigned long to store the slice size in fdisk(1). This
allows the user to specify a slice size up to the maximum permitted by
the MBR on-disk format and does not have any problems with silent
truncation should the use specify an slice size larger than 2^32 on systems
with sizeof(long) > 4.

Don't send EOI to the CPU before we handled the interrupt. This could
potentially trigger multiple pending interrupts for level-sensitive
interrupts. However, the event timer interrupt does need EOI before
being handled to avoid missing clock events.
These conflicting requirements are handled by having the XIV handler
inform the dispatch code whether or not it send EOI to the CPU. If not,
the dispatch code will do it. This allows handlers to send EOI before
doing potentially long-running activities, while still have a sensible
default behaviour.
Add a few more helper functions for working with memory descriptors:
o efi_md_find() - returns the md that covers the given address
o efi_md_last() - returns the last md in the list
o efi_md_prev() - returns the md that preceeds the given md.
