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.

the lock instead of queueing it to a task.
- Do not invoke jme_rxintr() to reclaim any unprocessed but received
packets when shutting down the interface. Instead, just drop these
packets to match the behavior of other drivers.
- Hold the driver lock in the interrupt handler to avoid races with
ioctl requests to down the interface.

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.

bus_size_t may be 32 or 64 bits. Change the bounce_zone alignment field
to explicitly be 32 bits, as I can't really imagine a DMA device that
needs anything close to 2GB alignment of data.
