Refreshed patches, removed upstreamed patch:

 generic/hack: 551-loop-Better-discard-support-for-block-devices.patch

Added generic config symbol `ARM64_ERRATUM_1542419` due to Fixes:
f2791551cedb ("arm64: errata: Hide CTR_EL0.DIC on systems affected by
Neoverse-N1 #1542419").

Run tested: qemu-x86-64, apalis, nbg6617
Build tested: x86/64, imx6, ipq40xx, sunxi/a53

From 3117c3f45edbcc269baaebd3d13f39b7bf884aa6 Mon Sep 17 00:00:00 2001

Subject: loop: Better discard support for block devices
If the backing device for a loop device is itself a block device,
then mirror the "write zeroes" capabilities of the underlying
block device into the loop device. Copy this capability into both
max_write_zeroes_sectors and max_discard_sectors of the loop device.
The reason for this is that REQ_OP_DISCARD on a loop device translates
into blkdev_issue_zeroout(), rather than blkdev_issue_discard(). This
presents a consistent interface for loop devices (that discarded data
is zeroed), regardless of the backing device type of the loop device.
There should be no behavior change for loop devices backed by regular
files.
This change fixes blktest block/003, and removes an extraneous
error print in block/013 when testing on a loop device backed
by a block device that does not support discard.
