2020-12-10iwlwifi: pcie: remove obsolete pre-release support codeEmmanuel Grumbach
We no longer need code that was introduced to differentiate between two early versions of 8260. We can remove this convoluted way to get the hardware version that was needed because of a bug in the register's configuration. Moreover, since we no longer need to access the PRPH registers, we no longer need to wake up the device, request ownership, etc... Remove all that. This allows us to get the rid of the obsolete comment about the AUX bus MISC address space which should have been moved when this code was moved away from here.

2020-12-09s390/mm: use invalid asce for user space when switching to init_mmHeiko Carstens
Currently only idle_task_exit() explicitly switches (switch_mm) to init_mm. This causes the kernel asce to be loaded into cr7 and therefore it would be used for potential user space accesses. This is currently no problem since idle_task_exit() is nearly the last thing a CPU executes before it is taken down. However things might change - and therefore make sure that always the invalid asce is used for cr7 when active_mm is init_mm. This makes sure that all potential user space accesses will fail, instead of accessing kernel address space.

2020-12-09s390/boot: add build-id to decompressorPhilipp Rudo
More and more functionality from the early boot phase gets carried over to the decompressor. With this the complexity of the code and thus the chance to introduce bugs increases. In order to be able to debug these early boot bugs the distributions have to package the decompressors vmlinux together with the other debuginfos. However for that the distributions require the vmlinux to contain a build-id. Per default the section containing the build-id is placed first in the section table. So make sure to move it behind the .text section otherwise the image would be unbootable. Signed-off-by: Philipp Rudo <prudo@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
