379663d70b o) Use ABI, not ISA_* options, to determine whether to compile bits if libkern
required for the ABI the kernel is being built for.
   XXX This is implemented in a kind-of nasty way that involves including source
       files, but it's still an improvement.
o) Retire ISA_* options since they're unused and were always wrong.

312af517e3 Remove platform APIs which are not used by any code and which had only stub
implementations or no implementation on all platforms.

Some of these functions might be good ideas, but their semantics were unclear
given the lack of implementation, and an unlucky porter could be fooled into
trying to implement them or, worse, being baffled when something like
platform_trap_enter() failed to be called.

4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.
  Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.

b67d11bbcc Change rman_manage_region() to actually honor the rm_start and rm_end
constraints on the rman and reject attempts to manage a region that is out
of range.
- Fix various places that set rm_end incorrectly (to ~0 or ~0u instead of
  ~0ul).
- To preserve existing behavior, change rman_init() to set rm_start and
  rm_end to allow managing the full range (0 to ~0ul) if they are not set by
  the caller when rman_init() is called.

1591f3f18c Allow the platform code to return a bitmask of running cores rather than just
a number of cores, this allows for a sparse set of CPUs.  Implement support
for sparse core masks on Octeon.

XXX jeff@ suggests that all_cpus should include cores that are offline or
    running other applications/OSes, so the platform API should be further
    extended to allow us to set all_cpus to include all cores that are
    physically-present as opposed to only those that are running FreeBSD.

611f086953 Support for 64 bit PTEs on n32 and n64 compilation.
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.

ab7a71f6e7 The message ring interrupt needs to be enabled for all cpus, not just
the ones which run the message ring handler.

Some bits of the interrupt mask are part of the status register which is
saved with the process context, and these bits are initialized from the
cpu on which the process is created. This means that all the processes
should have the same value for these interrupt mask bits, so that the
interrupt mask remains the same regardless of what thread is scheduled
on the cpu.

3e288e6238 After some off-list discussion, revert a number of changes to the
DPCPU_DEFINE and VNET_DEFINE macros, as these cause problems for various

8e5d93dbb4 Convert the PHY drivers to honor the mii_flags passed down and convert
the NIC drivers as well as the PHY drivers to take advantage of the
mii_attach() introduced in r213878 to get rid of certain hacks. For
the most part these were:
- Artificially limiting miibus_{read,write}reg methods to certain PHY
  addresses; we now let mii_attach() only probe the PHY at the desired
  address(es) instead.
- PHY drivers setting MIIF_* flags based on the NIC driver they hang
  off from, partly even based on grabbing and using the softc of the
  parent; we now pass these flags down from the NIC to the PHY drivers
  via mii_attach(). This got us rid of all such hacks except those of
  brgphy() in combination with bce(4) and bge(4), which is way beyond
  what can be expressed with simple flags.

While at it, I took the opportunity to change the NIC drivers to pass
up the error returned by mii_attach() (previously by mii_phy_probe())
and unify the error message used in this case where and as appropriate
as mii_attach() actually can fail for a number of reasons, not just
because of no PHY(s) being present at the expected address(es).
