8a5be36b93 powerpc updates for 5.11
- Switch to the generic C VDSO, as well as some cleanups of our VDSO
    setup/handling code.
 
  - Support for KUAP (Kernel User Access Prevention) on systems using the hashed
    page table MMU, using memory protection keys.
 
  - Better handling of PowerVM SMT8 systems where all threads of a core do not
    share an L2, allowing the scheduler to make better scheduling decisions.
 
  - Further improvements to our machine check handling.
 
  - Show registers when unwinding interrupt frames during stack traces.
 
  - Improvements to our pseries (PowerVM) partition migration code.
 
  - Several series from Christophe refactoring and cleaning up various parts of
    the 32-bit code.
 
  - Other smaller features, fixes & cleanups.

Here is the big driver core updates for 5.11-rc1
 
 This time there was a lot of different work happening here for some
 reason:
 	- redo of the fwnode link logic, speeding it up greatly
 	- auxiliary bus added (this was a tag that will be pulled in
 	  from other trees/maintainers this merge window as well, as
 	  driver subsystems started to rely on it)
 	- platform driver core cleanups on the way to fixing some
 	  long-time api updates in future releases
 	- minor fixes and tweaks.
 
 All have been in linux-next with no (finally) reported issues.  Testing
 there did helped in shaking issues out a lot :)

a353397b0d usb: gadget: f_fs: Re-use SS descriptors for SuperSpeedPlus
In many cases a function that supports SuperSpeed can very well
operate in SuperSpeedPlus, if a gadget controller supports it,
as the endpoint descriptors (and companion descriptors) are
generally identical and can be re-used. This is true for two
commonly used functions: Android's ADB and MTP. So we can simply
assign the usb_function's ssp_descriptors array to point to its
ss_descriptors, if available. Similarly, we need to allow an
epfile's ioctl for FUNCTIONFS_ENDPOINT_DESC to correctly
return the corresponding SuperSpeed endpoint descriptor in case
the connected speed is SuperSpeedPlus as well.

The only exception is if a function wants to implement an
Isochronous endpoint capable of transferring more than 48KB per
service interval when operating at greater than USB 3.1 Gen1
speed, in which case it would require an additional SuperSpeedPlus
Isochronous Endpoint Companion descriptor to be returned as part
of the Configuration Descriptor. Support for that would need
to be separately added to the userspace-facing FunctionFS API
which may not be a trivial task--likely a new descriptor format
(v3?) may need to be devised to allow for separate SS and SSP
descriptors to be supplied.
