  RISC-V: Fix the VDSO symbol generaton for binutils-2.35+ (2020-11-06 00:03:48 -0800)

----------------------------------------------------------------
RISC-V Fixes for 5.10-rc3

* An SPDX comment style fix.
* A fix to ignore memory that is unusable.
* A fix to avoid setting a kernel text offset for the !MMU kernels, where
  skipping the first page of memory is both unnecessary and costly.
* A fix to avoid passing the flag bits in satp to pfn_to_virt().
* A fix to __put_kernel_nofault, where we had the arguments to
  __put_user_nocheck reversed.
* A workaround for a bug in the FU540 to avoid triggering PMP issues during
  early boot.
* A change to how we pull symbols out of the vDSO.  The old mechanism was
  removed from binutils-2.35 (and has been backported to Debian's 2.34).
