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.

vm_map_free_{left,right} rather than re-implementing them. Use the
VM_MAP_FOREACH macro where applicable. Fix some indentation.

Rely on a system initialization done by a bootloader in that cases.

Based on POWER9BSD implementation, with all POWER9 specific code removed and
addition of new methods in PPC64 MMU interface, to isolate platform specific
code. Currently, the new methods are implemented on pseries and PowerNV
(D21643).

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.

instead of calling an SCTP specific function from the IP code.
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
code.

Previously they were defined in a header which was included exactly
once. Change this to follow the usual practice of putting definitions
in C files. No functional change intended.

On many filesystems the traversal is effectively a no-op. Add a way to avoid
the overhead.

It is a more natural fit. vfs_msync only deals with active vnodes.

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.
