cause harm in some edge cases.
- Even after masking the media with IFM_GMASK the result may have bits
besides the duplex ones set so just comparing it with IFM_FDX may lead
to false negatives.
- Announce PAUSE support also for manually selected 1000BASE-T, but for
all manually selected media types only in full-duplex mode. Announce
asymmetric PAUSE support only for manually selected 1000BASE-T.
- Simplify setting the manual configuration bits to only once after we
have figured them all out. This also means we no longer unnecessarily
update the hardware along the road.
- Remove a stale comment.

- Move the realtime priority range up above kernel sleep priorities and
just below interrupt thread priorities.
- Contract the interrupt and kernel sleep priority ranges a bit so that
the timesharing priority band can be increased. The new timeshare range
is now slightly larger than the old realtime + timeshare ranges.
- Change the ULE scheduler to no longer use realtime priorities for
interactive threads. Instead, the larger timeshare range is now split
into separate subranges for interactive and non-interactive ("batch")
threads. The end result is that interactive threads and non-interactive
threads still use the same priority ranges as before, but realtime
threads now have a separate, dedicated priority range.
- Do not modify the priority of non-timeshare threads in sched_sleep()
or via cv_broadcastpri(). Realtime and idle priority threads will
no longer have their priorities affected by sleeping in the kernel.

Mark gcc-provided asm files as not requiring executable stack.
It seems that non-FreeBSD ABIs for powerpc64 claim stack non-executable.
Due to this, rs6000_elf_end_indicate_exec_stack() only emit the note for
32 bit target. I decided not to change FreeBSD ABI and patch
emit the notes for both variants.

generated from lib/csu/common/crtbrand.c (which ultimately ends up in
executables and shared libraries, via crt1.o, gcrt1.o or Scrt1.o).
For all arches except sparc, gcc emits the section directive for the
abitag struct in crtbrand.c with a PROGBITS type. However, newer
versions of binutils (after 2.16.90) require the section to be of NOTE
type, to guarantee that the .note.ABI-tag section correctly ends up in
the first page of the final executable.
Unfortunately, there is no clean way to tell gcc to use another section
type, so crtbrand.c (or the C files that include it) must be compiled in
multiple steps:
- Compile the .c file to a .s file.
- Edit the .s file to change the 'progbits' type to 'note', for the section
directive that defines the .note.ABI-tag section.
- Compile the .s file to an object file.
These steps are done in the invididual Makefiles for each applicable arch.

started to execute, it seems that the corresponding ISR bit in the "old"
local APIC can be cleared. This causes the local APIC interrupt routine
to fail to find an interrupt to service. Rather than panic'ing in this
case, simply return from the interrupt without sending an EOI to the
local APIC. If there are any other pending interrupts in other ISR
registers, the local APIC will assert a new interrupt.

In n32 and n64, add support for physical address above 4GB by having
64 bit page table entries and physical addresses. Major changes are:
- param.h: update PTE sizes, masks and shift values to support 64 bit PTEs.
- param.h: remove DELAY(), mips_btop(same as atop), mips_ptob (same as
ptoa), and reformat.
- param.h: remove casting to unsigned long in trunc_page and round_page
since this will be used on physical addresses.
- _types.h: have 64 bit __vm_paddr_t for n32.
- pte.h: update TLB LO0/1 access macros to support 64 bit PTE
- pte.h: assembly macros for PTE operations.
- proc.h: md_upte is now 64 bit for n32 and n64.
- exception.S and swtch.S: use the new PTE macros for PTE operations.
- cpufunc.h: TLB_LO0/1 registers are 64bit for n32 and n64.
- xlr_machdep.c: Add memory segments above 4GB to phys_avail[] as they are
supported now.

1. Use vm_paddr_t for physical addresses.
There are a few places in the MIPS platform code where vm_offset_t is
used for physical addresses, change these to use vm_paddr_t:
- phys_avail[], physmem_desc[] arrays
- pmap_mapdev(), page_is_managed(), is_cacheable_mem() pmap_map() args
- local variables of various pmap functions
2. Change init_pte_prot() return from int to pt_entry_t, as this can be
64 bit when using 64 bit TLB entries.
3. Update printing of pt_entry_t and of vm_paddr_t to use 'j' format with
uintmax_t. This will be useful later if we plan to use 64bit phsical addr
on 32 bit n32 compilation.
