Merge patch series "RISC-V: Apply Zicboz to clear_page"

Andrew Jones <ajones@ventanamicro.com> says:

When the Zicboz extension is available we can more rapidly zero naturally
aligned Zicboz block sized chunks of memory. As pages are always page
aligned and are larger than any Zicboz block size will be, then
clear_page() appears to be a good candidate for the extension. While cycle
count and energy consumption should also be considered, we can be pretty
certain that implementing clear_page() with the Zicboz extension is a win
by comparing the new dynamic instruction count with its current count[1].
Doing so we see that the new count is just over a quarter of the old count
(see patch6's commit message for more details).

For those of you who reviewed v1[2], you may be looking for the memset()
patches. As pointed out in v1, and a couple follow-up emails, it's not
clear that patching memset() is a win yet. When I get a chance to test
on real hardware with a comprehensive benchmark collection then I can
post the memset() patches separately (assuming the benchmarks show it's
worthwhile).

* b4-shazam-merge:
RISC-V: KVM: Expose Zicboz to the guest
RISC-V: KVM: Provide UAPI for Zicboz block size
RISC-V: Use Zicboz in clear_page when available

RISC-V: alternatives: Support patching multiple insns in assembly

As pointed out in commit d374a16539b1 ("RISC-V: fix compile error
from deduplicated __ALTERNATIVE_CFG_2"), we need quotes around
parameters passed to macros within macros to avoid spaces being
interpreted as separators. ALT_NEW_CONTENT was trying to handle
this by defining new_c has a vararg, but this isn't sufficient
for calling ALTERNATIVE() from assembly with multiple instructions
in the new/old sequences. Remove the vararg "hack" and use quotes.
