Hi,

This series makes a few improvements to /proc/kcore. Patches 1 and 2 are
prep patches. Patch 3 is a fix/cleanup. Patch 4 is another prep patch.
Patches 5 and 6 are optimizations to ->read(). Patch 7 adds vmcoreinfo
to /proc/kcore. This series is based on v4.18-rc3. Please consider it
for v4.19.

Thanks!
