kernel: copy kernel 4.19 code to 5.4 No changes were done to the patches while coping them. Currently they do not apply on top of kernel 5.4. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

From: Felix Fietkau <nbd@nbd.name>
Subject: kernel: disable cfi cmdset 0002 erase suspend
on some platforms, erase suspend leads to data corruption and lockups when write
ops collide with erase ops. this has been observed on the buffalo wzr-hp-g300nh.
rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,
simply disable erase suspend, as it will usually not produce any useful gain on
the small filesystems used on embedded hardware.
