Subject: [PATCH 0/2] Revert boot-breaking changes in fs/

next-20230213 introduced commit d9722a475711 ("splice: Do splice read from
a buffered file without using ITER_PIPE") which broke booting on any
Qualcomm ARM64 device I grabbed, dereferencing a null pointer in
generic_filesplice_read+0xf8/x598. Revert it (and its dependency)
(or accept better solutions should anybody come up with such) to make
them bootable again.
