Linus Torvalds 0cec3f24a7 arm64 updates for 5.20
- Remove unused generic cpuidle support (replaced by PSCI version)
 
 - Fix documentation describing the kernel virtual address space
 
 - Handling of some new CPU errata in Arm implementations
 
 - Rework of our exception table code in preparation for handling
   machine checks (i.e. RAS errors) more gracefully
 
 - Switch over to the generic implementation of ioremap()
 
 - Fix lockdep tracking in NMI context
 
 - Instrument our memory barrier macros for KCSAN
 
 - Rework of the kPTI G->nG page-table repainting so that the MMU remains
   enabled and the boot time is no longer slowed to a crawl for systems
   which require the late remapping
 
 - Enable support for direct swapping of 2MiB transparent huge-pages on
   systems without MTE
 
 - Fix handling of MTE tags with allocating new pages with HW KASAN
 
 - Expose the SMIDR register to userspace via sysfs
 
 - Continued rework of the stack unwinder, particularly improving the
   behaviour under KASAN
 
 - More repainting of our system register definitions to match the
   architectural terminology
 
 - Improvements to the layout of the vDSO objects
 
 - Support for allocating additional bits of HWCAP2 and exposing
   FEAT_EBF16 to userspace on CPUs that support it
 
 - Considerable rework and optimisation of our early boot code to reduce
   the need for cache maintenance and avoid jumping in and out of the
   kernel when handling relocation under KASLR
 
 - Support for disabling SVE and SME support on the kernel command-line
 
 - Support for the Hisilicon HNS3 PMU
 
 - Miscellanous cleanups, trivial updates and minor fixes

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Will Deacon:
 "Highlights include a major rework of our kPTI page-table rewriting
  code (which makes it both more maintainable and considerably faster in
  the cases where it is required) as well as significant changes to our
  early boot code to reduce the need for data cache maintenance and
  greatly simplify the KASLR relocation dance.

  Summary:

   - Remove unused generic cpuidle support (replaced by PSCI version)

   - Fix documentation describing the kernel virtual address space

   - Handling of some new CPU errata in Arm implementations

   - Rework of our exception table code in preparation for handling
     machine checks (i.e. RAS errors) more gracefully

   - Switch over to the generic implementation of ioremap()

   - Fix lockdep tracking in NMI context
