- fix buffer size for in-kernel disassembler for ebpf programs. - fix two memory leaks in zcrypt driver. - expose PCI device UID as index, including an indicator if the uid is unique. - remove some oprofile leftovers. - improve stack unwinder tests. - don't use gcc atomic builtins anymore, just like all other architectures. Even though I'm sure the current code is ok, I totally dislike that s390 is the only architecture being special here; especially considering that there was a lengthly discussion about this topic and the outcome was not to use the builtins. Therefore open-code atomic ops again with inline assembly and switch to gcc builtins as soon as other architectures are doing. - couple of other changes to atomic and cmpxchg, and use atomic-instrumented.h for KASAN. - separate zbus creation, registration, and scanning in our PCI code which allows for cleaner and easier handling. - a rather large change to the vfio-ap code to fix circular locking dependencies when updating crypto masks. - move QAOB handling from qdio layer down to drivers. - add CRW inject facility to common I/O layer. This adds debugs files which allow to generate artificial events from user space for testing purposes. - increase SCLP console line length from 80 to 320 characters to avoid odd wrapped lines. - add protected virtualization guest and host indication files, which indicate either that a guest is running in pv mode or if the hypervisor is capable of starting pv guests. - various other small fixes and improvements all over the place. -----BEGIN PGP SIGNATURE----- iQIyBAABCAAdFiEECMNfWEw3SLnmiLkZIg7DeRspbsIFAmCICNwACgkQIg7DeRsp bsJgSQ/0Cn3KTymF8SJ7tXLpYBNHmZBL1sQ284pPNYmqluwephUaX643f/48RR5y rlbaewyHCbYyR+gwkUykuUQm/d+iwihip/uFmyEktr9JutOOS1RQKd8ujeyE2BUb aaDyE0J5VFYdd/ZA92n9FhkuNDOMZRFAK1SOfifT9jNWCl8iYz+pXV1Gx7LbJYVY KWfJ9D/zgzLoOTWhj4jWu8LutfLEqK+hq5nqxBII8APCV/QDYnjkwpwW01LoMtOv eHhtSz0JboFRk0FYf8oyR7AXQBz76+Ru3aivJNL7sr1S3N2yMSzNQbk/ATVBLER9 VMQX2TfGGT/Ln3P4rYEoP2vGITRn765wg4KWNB2u3pY2try12G39fmjzOwVfbxQw BDAcLwxU7Tw0vJY+yI6ZWkPDXcs+uAWQwNiYoMtfUPfMYLEpLFffbWGwdZPKZRrH fy4e5ZFuavZsZr8Zeu4WYILJZoDnvhbs59gPzaLBPKosR0ZGNi8q6bnztnqnrYhi Oirt6aPOOyEoN/IT2bO1sDhIzIpCorIwCMZTRIQzerFRcjJgy0xHM9MRYRLMj6iW xltgWNt01SbTm6pbimwMUnjN5AdMTbHlTSzD8G34eWO21cVgHGpndbcT/M3uemyy Wf034Er2eFqlhXyhiAYTnNhVGbd+YMido7eo/CbGvqCxNvmKbA== =e+mh -----END PGP SIGNATURE----- Merge tag 's390-5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Heiko Carstens: - fix buffer size for in-kernel disassembler for ebpf programs. - fix two memory leaks in zcrypt driver. - expose PCI device UID as index, including an indicator if the uid is unique. - remove some oprofile leftovers. - improve stack unwinder tests. - don't use gcc atomic builtins anymore, just like all other architectures.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
