Merge tag 'riscv-mw1-6.15-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/alexghiti/linux into for-next
riscv patches for 6.15-rc1
* A bunch of fixes:
- We were missing a secondary mmu notifier call when flushing the tlb which is required for IOMMU
- Fix ftrace panics by saving the registers as expected by ftrace
- Fix a couple of stimecmp usage related to cpu hotplug
- Fix a bunch of issues in the misaligned probing handling
* Perf improvements:
- Introduce support for runtime constant improving perf of d_hash()
- Add support for huge pfnmaps to improve tlb utilization
- Use Zawrs to improve smp_cond_load8/16() used by the queued spinlocks
* Hwprobe additions:
- Add support for Zicntr and Zihpm
- Add support for Zaamo and Zalrsc
- Add support for bfloat16 extensiosn
- Add support for Zicbom (only enabling clean and flush, not inval for security reasons)
* Misc:
- Add a kernel parameter to bypass the misaligned speed probing since we can't rely on Zicclsm
* tag 'riscv-mw1-6.15-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/alexghiti/linux: (1585 commits)
