reboot.2: Fix bogus description of reboot() from non-initial PID namespace
...
The current text was confused (mea culpa). No signal is sent to
the init() process. Rather, depending on the 'cmd' given to
reboot(), the 'group_exit_code' value will set to either SIGHUP or
SIGINT, with the effect that one of those signals is reported to
wait() in the parent process.

...
hugetlbfs support for memfd_create() was recently merged by Linus
and should be in the Linux 4.14 release. To request hugetlbfs
support a new memfd_create() flag (MFD_HUGETLB) was added.

mremap.2: Add description of old_size == 0 functionality
...
Since at least the 2.6 time frame, mremap() would create a new
mapping of the same pages if 'old_size == 0'. It would also leave
the original mapping. This was used to create a 'duplicate
mapping'.
A recent change was made to mremap() so that an attempt to create a
duplicate a private mapping will fail.
Document the 'old_size == 0' behavior and new return code from
below commit.
