- Use a default -march of mips64 on N64 and N32 kernels.
- Set the endianness (via MIPS_ENDIAN) and ABI (via MIPS_ABI) in
CFLAGS from MACHINE_ARCH. ARCH_FLAGS now only sets a different
-march value if needed.
- TRAMP_ARCH_FLAGS inherits MIPS_ENDIAN from MACHINE_ARCH but does
not set the ABI since XLPN32 needs an N64 ABI for the trampoline
loader. When TRAMP_ARCH_FLAGS is used it must set both -march
and -mabi.

10572 Fix race in dnode_check_slots_free()
https://www.illumos.org/issues/10572
The Fix from ZoL:
Currently, dnode_check_slots_free() works by checking dn->dn_type
in the dnode to determine if the dnode is reclaimable. However,
there is a small window of time between dnode_free_sync() in the
first call to dsl_dataset_sync() and when the useraccounting code
is run when the type is set DMU_OT_NONE, but the dnode is not yet
evictable, leading to crashes. This patch adds the ability for
dnodes to track which txg they were last dirtied in and adds a
check for this before performing the reclaim.
This patch also corrects several instances when dn_dirty_link was
treated as a list_node_t when it is technically a multilist_node_t.
10579 Don't allow dnode allocation if dn_holds != 0
https://www.illumos.org/issues/10579
The fix from ZoL:
This patch simply fixes a small bug where dnode_hold_impl() could
attempt to allocate a dnode that was in the process of being freed,
but which still had active references. This patch simply adds the
required check.

By default next_cmd() initializes only first u32 of opcode. O_ICMP6TYPE
opcode has array of bit masks to store corresponding ICMPv6 types.
An opcode that precedes O_ICMP6TYPE, e.g. O_IP6_DST, can have variable
length and during opcode filling it can modify memory that will be used
by O_ICMP6TYPE opcode. Without explicit initialization this leads to
creation of wrong opcode.

busy acquires while held.
This allows code that would need to acquire and release a very large number
of page busy locks to use the old mechanism where busy is only checked and
not held. This comes at the cost of false positives but never false
negatives which the single consumer, vm_fault_soft_fast(), handles.

The wrong toolchain was set in MAKE_PARAMS_powerpc, however, there are
some other issues preventing powerpc from building in tinderbox:
1) There is no powerpc-gcc and powerpc-xtoolchain-gcc port that
provides an external 32-bit powerpc GCC toolchain.
2) On other targets, the same toolchain can build all of the
architectures for a given target. MIPS achieves this by always
setting -mabi and -EB/-EL explicitly instead of relying on the
compiler's default architecture. PowerPC might be able to do the
same thing, but as of today, powerpc-gcc would be required for
powerpc and powerpcspe and powerpc64-gcc would be required for
powerpc64. Our existing logic for make universe does not permit
per-MACHINE_ARCH toolchains.
I tried hacking TARGETS_powerpc to only include powerpc64 when
powerpc64-gcc was present, and while that skipped the 32-bit worlds,
it tried to build all the kernels.

The former spelling probably confused MOVDIR64B with MOVDIRI64.
MOVDIR_64B is the 64-*byte* direct store instruction; MOVDIR_I64 is the
64-*bit* direct store instruction (underscores added here for clarity; they are
not part of the canonical instruction name).
No functional change.
