I am always trying not to forget to rebase on top of staging for this
patch series:

65c49e7aa2 (HEAD -> riscv-dt-support-v8, origin/riscv-dt-support-v8)
xen/riscv: introduce early_fdt_map()
ead52f68ce xen/riscv: page table handling
c3aba0520f xen/riscv: introduce and initialize SBI RFENCE extension
3ffb3ffd38 xen/riscv: introduce functionality to work with CPU info
4bfd2bfdb2 xen/riscv: introduce asm/pmap.h header
87bc91db10 xen/riscv: set up fixmap mappings
09b925f973 xen/riscv: allow write_atomic() to work with non-scalar
types
625ee7650c xen/README: add compiler and binutils versions for RISC-V64
5379a23ad7 xen/riscv: test basic exception handling stuff
2b6fb9f3c4 (origin/staging, origin/HEAD, staging) blkif: Fix a couple
of typos
6e73a16230 blkif: Fix alignment description for discard request
0111c86bfa x86/boot: Refactor BIOS/PVH start

Only some patches have been merged today to staging on top of "blkif:
Fix a couple of typos".

It shouldn't be any issue with applying patches from these patch
series.
