From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Ilya Dryomov <idryomov@gmail.com>
Date: Fri, 3 May 2019 17:27:03 +0200
Subject: [PATCH] rbd: don't assert on writes to snapshots
The check added in commit 721c7fc701c7 ("block: fail op_is_write()
requests to read-only partitions") was lifted in commit a32e236eb93e
("Partially revert "block: fail op_is_write() requests to read-only
partitions""). Basic things like user triggered writes and discards
are still caught, but internal kernel users can submit anything. In
particular, ext4 will attempt to write to the superblock if it detects
errors in the filesystem, even if the filesystem is mounted read-only
on a read-only partition.
The assert is overkill regardless.

Subject: [PATCH] x86/fpu: backport copy_kernel_to_XYZ_err helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
partial cherry-pick from upstream 5.2 "86/fpu: Restore from kernel
memory on the 64-bit path too"
commit 926b21f37b072ae4c117052de45a975c6d468fec
Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Namely, only backport the added helpers, none of the semantic changes.
relevant parts of the original commit message:
> In order to avoid that mess, copy the FPU state from userland, validate
> it and then load it. The copy_kernel_…() helpers are basically just
> like the old helpers except that they operate on kernel memory and the
> fault handler just sets the error value and the caller handles it.
