Merge tag 'riscv-for-linus-6.14-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V updates from Palmer Dabbelt:

 - The PH1520 pinctrl and dwmac drivers are enabeled in defconfig

 - A redundant AQRL barrier has been removed from the futex cmpxchg
   implementation

 - Support for the T-Head vector extensions, which includes exposing
   these extensions to userspace on systems that implement them

 - Some more page table information is now printed on die() and systems
   that cause PA overflows
