Merge tag 'sparc-for-6.10-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/alarsson/linux-sparc

Pull sparc updates from Andreas Larsson:

 - Avoid on-stack cpumask variables in a number of places

 - Move struct termio to asm/termios.h, matching other architectures and
   allowing certain user space applications to build also for sparc

 - Fix missing prototype warnings for sparc64

 - Fix version generation warnings for sparc32

 - Fix bug where non-consecutive CPU IDs lead to some CPUs not starting

 - Simplification using swap and cleanup using NULL for pointer

 - Convert sparc parport and chmc drivers to use remove callbacks
   returning void
