While here generate code for different variants of getcc() using a macro
GETCC(sz) where 'sz' indicates the operand size.

of this patch, resumectx() called npxresume() directly, but that doesn't
work because resumectx() runs with a non-standard %cs selector. Instead,
all of the FPU suspend/resume handling is done in C.

optional attributes field.
- Add a 'machdep.smap' sysctl that exports the SMAP table of the running
system as an array of the ACPI 3.0 structure. (On older systems, the
attributes are given a value of zero.) Note that the sysctl only
exports the SMAP table if it is available via the metadata passed from
the loader to the kernel. If an SMAP is not available, an empty array
is returned.
- Add a format handler for the ACPI 3.0 SMAP structure to the sysctl(8)
binary to format the SMAP structures in a readable format similar to
the format found in boot messages.

- use proper __FreeBSD_version check and more importantly check for __am64__

different question.
- cast uint64_t to uintmax_t and use %jx for printing.
Note: there are more values that could be printed in that status function
but leave that for the future; printf doesn't seem to be the right
way to do it anyway.
Note: there is more breakage related to i40e_allocate_dma*() having
conflicting declarations, so more fixes to come.

e.g. when a global variable is initialized with a pointer to ifunc.
Add symbol type check and call resolver for STT_GNU_IFUNC symbol types
when processing non-PLT relocations, but only after non-IFUNC
relocations are done. The two-phase proceessing is required since
resolvers may reference other symbols, which must be ready to use when
resolver calls are done.
Restructure reloc_non_plt() on x86 to call find_symdef() and handle
IFUNC in single place.
For non-x86 reloc_non_plt(), check for call for IFUNC relocation and
do nothing, to avoid processing relocs twice.

- Rename $kerberos5_server_enable with $kdc_enable and rename
rc.d/kerberos with rc.d/kdc.
- Rename $kadmin5_server_enable with $kadmind_enable.
- Rename ${kerberos5,kpasswdd}_server with ${kdc,kpasswdd}_program.
- Fix rc.d/{kadmind,kerberos,kpasswdd,kfd} scripts not to change variables
after load_rc_config().
- Add rc.d/ipropd_master and rc.d/ipropd_slave scripts. These are
for iprop-master(8) and iprop-slave(8). Keytab used for iprop service is
defined in ipropd_{master,slave}_keytab (/etc/krb5.keytab by default).
- Add dependency on rc.d/kdc to SERVERS. rc.d/kdc must be invoked as early
as possible before scripts divided by rc.d/SERVERS.
Note that changes to rc.d/{kdc,kpasswdd,kadmind} are backward-compatible
with the old configuration variables:
${kerberos5,kpasswdd,kadmin5}_server{,_enable,_flags}.
Prior to this change we triggered ARC reclaim when kmem usage passed 3/4
of the total available, as indicated by vmem_size(kmem_arena, VMEM_ALLOC).
This could lead large amounts of unused RAM e.g. on a 192GB machine with
ARC the only major RAM consumer, 40GB of RAM would remain unused.
The old method has also been seen to result in extreme RAM usage under
certain loads, causing poor performance and stalls.
We now trigger ARC reclaim when the number of free pages drops below the
value defined by the new sysctl vfs.zfs.arc_free_target, which defaults
to the value of vm.v_free_target.
