Thanks for the patch.
One thing I am planning to do is to create some kind of semi-automatic
script to extract the syscall info from Linux headers. This
reorganization would make things harder in this area, so I propose that
you just include the group information to each syscall, without
modifying the current order.

gdb/syscalls doesn't have a ChangeLog file, so your ChangeLog entry will
have to be included in the gdb/ChangeLog file, and will have to refer to
syscalls/amd64-linux.xml.
