Hi all,

Warning: Some of the branches in linux-next may still based on v5.12-rc1,
so please be careful if you are trying to bisect a bug.

News: if your -next included tree is based on Linus' tree tag
v5.12-rc1{,-dontuse} (or somewhere between v5.11 and that tag), please
consider rebasing it onto v5.12-rc2. Also, please check any branches
merged into your branch.

Changes since 20210318:

The net-next tree gained a conflict against the net tree.

The amdgpu tree gained a build failure so I used the version from
next-20210318.

The security tree gained a conflict against the ext3 tree.

The rcu tree lost its build failure.

The akpm-current tree still had its build failure for which I applied
a hack.

The akpm tree gained a conflict against the security tre.

Merging rust/rust-next (8ef6f74a3571 Rust support)

This breaks now on s390 with commit 8ef6f74a3571 ("Rust support").
make modules_install / depmod now fails with:

depmod: WARNING: /.../lib/modules/5.12.0-rc3-00001-g8ef6f74a3571/kernel/drivers/s390/scsi/zfcp.ko needs unknown symbol

for every module (yes, the line is complete).
