uapi: asm-generic: fcntl: Fix typo 'the the' in comment (2022-07-22
14:54:22 +0200)
----------------------------------------------------------------
asm-generic: updates for 6.0
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.
