2024-07-01s390/sclp: Add timeout to Store Data requestsPeter Oberparleiter
Due to a bug in some firmware versions, Store Data requests might not get an event response in certain situations. As a result, the boot process will be blocked indefinitely. Fix this by introducing timeout handling for Store Data requests. In case a timeout occurs, the Store Data operation is halted and no data is retrieved from the SCLP facility. Note: A minority of installed systems rely on Store Data result for device auto-configuration. These systems will fail to boot in case of a Store Data timeout and will need to be switched to manual device configuration as workaround.

2024-07-01s390/sclp: Prevent release of buffer in I/OPeter Oberparleiter
When a task waiting for completion of a Store Data operation is interrupted, an attempt is made to halt this operation. If this attempt fails due to a hardware or firmware problem, there is a chance that the SCLP facility might store data into buffers referenced by the original operation at a later time. Handle this situation by not releasing the referenced data buffers if the halt attempt fails. For current use cases, this might result in a leak of few pages of memory in case of a rare hardware/firmware malfunction.

2024-07-01s390/sclp: Suppress unnecessary Store Data warningPeter Oberparleiter
On systems that do not support Store Data events (such as when running as KVM guest) the following warning message appears during boot: sclp_sd: Store Data request failed (eq=2, di=3, response=0x40f0, flags=0x00, status=0, rc=-5) This warning does not add any useful information since the result is expected due to missing support for that event type. Suppress this message by checking the associated masks of supported events before issuing a Store Data event.

2024-06-24s390/mm: Get total ram pages from memblockWei Yang
On s390, zero page's size relies on total ram pages. Since we plan to move the accounting into __free_pages_core(), totalram_pages may not represent the total usable pages on system at this point when defer_init is enabled. We can get the total usable pages from memblock directly. The size maybe not accurate due to the alignment, but enough for the calculation.

2024-06-05s390/uv: Split large folios in gmap_make_secure()David Hildenbrand
While s390x makes sure to never have PMD-mapped THP in processes that use KVM -- by remapping them using PTEs in thp_split_walk_pmd_entry()->split_huge_pmd() -- there is still the possibility of having PTE-mapped THPs (large folios) mapped into guest memory. This would happen if user space allocates memory before calling KVM_CREATE_VM (which would call s390_enable_sie()). With upstream QEMU, this currently doesn't happen, because guest memory is setup and conditionally preallocated after KVM_CREATE_VM. Could it happen with shmem/file-backed memory when another process allocated memory in the pagecache? Likely, although currently not a common setup. Trying to split any PTE-mapped large folios sounds like the right and future-proof thing to do here. So let's call split_folio() and handle the return values accordingly.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty Pull tty fix from Greg KH: "Here is a single revert for a much-reported regression in 6.10-rc1 when it comes to a few older architectures. Turns out that the VT ioctls don't work the same across all cpu types because of some old compatibility requrements for stuff like alpha and powerpc. So revert the change that attempted to have them use the _IO() macros and go back to the known-working values instead. This has NOT been in linux-next but has had many reports that it fixes the issue with 6.10-rc1" * tag 'tty-6.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: Revert "VT: Use macros to define ioctls"
