f5523801a3 MFp4:
- Remove unnecessary NULL checks after M_WAITOK allocations.
 - Use VOP_ACCESS instead of hand-rolled suser_cred()
   calls. [1]
 - Use malloc(9) KPI to allocate memory for string.  The
   optimization taken from NetBSD is not valid for FreeBSD
   because our malloc(9) already act that way. [2]

ef518e4122 MFp4: Add tmpfs, an efficient memory file system.
Please note that, this is currently considered as an
experimental feature so there could be some rough
edges.  Consult http://wiki.freebsd.org/TMPFS for
more information.

For now, connect tmpfs to build on i386 and amd64
architectures only.  Please let us know if you have
success with other platforms.

This work was developed by Julio M. Merino Vidal
for NetBSD as a SoC project; Rohit Jalan ported it
from NetBSD to FreeBSD.  Howard Su and Glen Leeder
are worked on it to continue this effort.

Obtained from:	NetBSD via p4
