Linus,
Please pull these RISC-V updates for v6.18-rc7. v6.18 looks like it's
settling down well for us. Am currently expecting to have one additional
fix with very limited scope coming in next week, after v6.18-rc7 is
tagged.
To my eyes, the only notable patch in this PR is a patch to deal with MIPS
getting their RISC-V/JEDEC vendor ID wrong. Apparently this didn't affect
their testing, because they've told us that their QEMU platform was also
using the wrong vendor ID. (They are fixing upstream QEMU.) The patch
that added the incorrect vendor ID only went in for the v6.18 merge
window. So the good news is that we can fix this before the final v6.18
release is tagged. Speaking with MIPS off-list, they've assured us that
they will start testing on FPGA bitstreams now, so I hope this will be a
closed issue going forward.

----------------------------------------------------------------
RISC-V updates for v6.18-rc7
- Correct the MIPS RISC-V/JEDEC vendor ID.
- Fix the system shutdown behavior in the legacy case where
CONFIG_RISCV_SBI_V01 is set, but the firmware implementation doesn't
support the older v0.1 system shutdown method.
- Align some tools/ macro definitions with the corresponding kernel headers.
