RISC-V Fixes for 5.10-rc3

Browse source

* 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).
