Subject: [GIT PULL] s390 patches for the 4.17 merge window #1
Hi Linus,
please pull from the 'for-linus' branch of
git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus
to receive the following updates:
* Improvements for the spectre defense:
- The spectre related code is consolidated to a single file nospec-branch.c
- Automatic enable/disable for the spectre v2 defenses (expoline vs. nobp)
- Syslog messages for specve v2 are added
- Enable CONFIG_GENERIC_CPU_VULNERABILITIES and define the attribute
functions for spectre v1 and v2
* Add helper macros for assembler alternatives and use them to shorten
the code in entry.S.
* Add support for persistent configuration data via the SCLP Store Data
interface. The H/W interface requires a page table that uses 4K pages
only, the code to setup such an address space is added as well.
* Enable virtio GPU emulation in QEMU. To do this the depends statements
for a few common Kconfig options are modified.
* Add support for format-3 channel path descriptors and add a binary
sysfs interface to export the associated utility strings.
* Add a sysfs attribute to control the IFCC handling in case of constant
channel errors.
* The vfio-ccw changes from Cornelia.
* Bug fixes and cleanups.
There is a trivial merge conflict in drivers/video/console/Kconfig.
