Merge tag 'asm-generic-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic updates from Arnd Bergmann:
"There are three independent sets of changes:
- Sai Prakash Ranjan adds tracing support to the asm-generic version
of the MMIO accessors, which is intended to help understand
problems with device drivers and has been part of Qualcomm's vendor
kernels for many years
- A patch from Sebastian Siewior to rework the handling of IRQ stacks
in softirqs across architectures, which is needed for enabling
PREEMPT_RT
- The last patch to remove the CONFIG_VIRT_TO_BUS option and some of
the code behind that, after the last users of this old interface
made it in through the netdev, scsi, media and staging trees"
