- Various virtual vs physical address usage fixes
- Fix error handling in Processor Activity Instrumentation device driver, and
export number of counters with a sysfs file
- Allow for multiple events when Processor Activity Instrumentation counters
are monitored in system wide sampling
- Change multiplier and shift values of the Time-of-Day clock source to improve
steering precision
- Remove a couple of unneeded GFP_DMA flags from allocations
- Disable mmap alignment if randomize_va_space is also disabled, to avoid a too
small heap
- Various changes to allow s390 to be compiled with LLVM=1, since ld.lld and
llvm-objcopy will have proper s390 support witch clang 19
- Add __uninitialized macro to Compiler Attributes. This is helpful with s390's
FPU code where some users have up to 520 byte stack frames. Clearing such
stack frames (if INIT_STACK_ALL_PATTERN or INIT_STACK_ALL_ZERO is enabled)
before they are used contradicts the intention (performance improvement) of
such code sections.
- Convert switch_to() to an out-of-line function, and use the generic switch_to
header file
- Replace the usage of s390's debug feature with pr_debug() calls within the
zcrypt device driver
- Improve hotplug support of the Adjunct Processor device driver
- Improve retry handling in the zcrypt device driver
- Various changes to the in-kernel FPU code:
- Make in-kernel FPU sections preemptible
- Convert various larger inline assemblies and assembler files to C, mainly
by using singe instruction inline assemblies. This increases readability,
but also allows makes it easier to add proper instrumentation hooks
- Cleanup of the header files
- Provide fast variants of csum_partial() and csum_partial_copy_nocheck() based
on vector instructions
- Introduce and use a lock to synchronize accesses to zpci device data
structures to avoid inconsistent states caused by concurrent accesses
- Compile the kernel without -fPIE. This addresses the following problems if
the kernel is compiled with -fPIE:
- It uses dynamic symbols (.dynsym), for which the linker refuses to allow
more than 64k sections. This can break features which use
'-ffunction-sections' and '-fdata-sections', including kpatch-build and
function granular KASLR
- It unnecessarily uses GOT relocations, adding an extra layer of indirection
for many memory accesses
- Fix shared_cpu_list for CPU private L2 caches, which incorrectly were
reported as globally shared
