Hi Linus,
please pull s390 updates for the 6.6 merge window.
There will be a merge conflict with Andrew's mm-nonmm-stable tree.
Since the diff of the merge resolution is quite large I'm going to
reply to this mail.
Thanks,
Heiko
The following changes since commit 6eaae198076080886b9e7d57f4ae06fa782f90ef:
Linux 6.5-rc3 (2023-07-23 15:24:10 -0700)
are available in the Git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git tags/s390-6.6-1

s390/pci: use builtin_misc_device macro to simplify the code (2023-08-23 14:37:42 +0200)
----------------------------------------------------------------
s390 updates for 6.6 merge window
- Add vfio-ap support to pass-through crypto devices to secure execution
guests
- Add API ordinal 6 support to zcrypt_ep11misc device drive, which is
required to handle key generate and key derive (e.g. secure key to
protected key) correctly
- Add missing secure/has_secure sysfs files for the case where it is not
possible to figure where a system has been booted from. Existing user
space relies on that these files are always present
- Fix DCSS block device driver list corruption, caused by incorrect
error handling
- Convert virt_to_pfn() and pfn_to_virt() from defines to static inline
functions to enforce type checking
- Cleanups, improvements, and minor fixes to the kernel mapping setup
- Fix various virtual vs physical address confusions
- Move pfault code to separate file, since it has nothing to do with
regular fault handling
- Move s390 documentation to Documentation/arch/ like it has been done
for other architectures already
- Add HAVE_FUNCTION_GRAPH_RETVAL support
- Factor out the s390_hypfs filesystem and add a new config option for
it. The filesystem is deprecated and as soon as all users are gone it
can be removed some time in the not so near future
- Remove support for old CEX2 and CEX3 crypto cards from zcrypt device
driver
- Add support for user-defined certificates: receive user-defined
certificates with a diagnose call and provide them via 'cert_store'
keyring to user space
- Couple of other small fixes and improvements all over the place

Maybe I'm doing something wrong, but below is the rather large diff
of the merge commit, using "git diff HEAD HEAD^@", where HEAD is the

Something weird there. I just see the arch/s390/Kconfig part (I use
git diff-tree <merge commit>). What did you merge?
I can't see any commits affecting kernel/Kconfig.kexec in the s390
branch in linux-next.

Actually I use "git diff-tree --cc <merge commit>"

There is logical conflict between
commit 37002bc6b603 ("docs: move s390 under arch")
from the s390 tree:
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux tags/s390-6.6-1
and
commit 89cde455915f ("kexec: consolidate kexec and crash options into kernel/Kconfig.kexec")
from Andrew's tree:
git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm mm-nonmm-stable
The commit in Andrew's tree introduces kernel/Kconfic.kexec and uses the
old location for Documentation (which is correct for Andrew's tree). So
when merging the s390 tree and Andrew's tree into Linus' tree that should
be fixed as well (btw.: this is not "fixed" in linux-next).
So I guess the size of the merge commit diff is simply a result of
kernel/Kconfig.exec not being present in both trees and being modified with
the merge, and therefore the complete file is part of the diff.
