addition of new methods in PPC64 MMU interface, to isolate platform specific
code. Currently, the new methods are implemented on pseries and PowerNV

There are cases where there's no vm_page_t structure for a given physical
address, such as the CCSR. In this case, trying to obtain the
md.page_tracked struct member would lead to a NULL dereference, and panic.
Tighten this up by checking for kernel_pmap AND that the page structure
actually exists before dereferencing. The flag can only be set when it's
tracked in the kernel pmap anyway.

This is a requirement of supporting SCTP as a kernel loadable module.
This patch was developed by markj@, I tweaked a bit the SCTP related

Previously they were defined in a header which was included exactly
once. Change this to follow the usual practice of putting definitions

The TDP_NOFAULTING flag should be checked in vm_fault(), not in
vm_fault_trap(). Otherwise kernel accesses to userspace, like
vn_io_fault(), enter vm locking when it should not.

Also fix non-standard nomenclature in the Caps code, and update the

The logic in XX_IsPortalIntr() was reading past the end of XX_PInfo.
This was causing it to erroneously return 1 instead of 0 in some
circumstances, causing a panic on the AmigaOne X5000 due to mixing
exclusive and nonexclusive interrupts on the same interrupt line.
Since this code is only called a couple of times during startup, use
a simple double loop instead of the complex read-ahead single loop.
This also fixes a bug where it would never check cpu=0 on type=1.

This changes the printed format, so anything that scrapes and parses

Since we are trying to bind device interrupt threads to the device domain,
it should have sense to make memory often accessed by them local. If domain
is not known, fall back to round-robin.

Node' cdp.si_name is the full path as provided by make_dev(9), it

With this note, handling of VDIR and VCHR nodes only differs in
