Despite of the fact that it can be considered as bugfixes, it seems to
me that this patch series can be risky. Let's wait for maintainers

Final commits: from July 5 to July 12

The release date is shifted, but it still remains in July, which seems
acceptable to me.
One more thing:
No release ack is needed before Rc1. Please commit bug fixes at will.
Have a nice day.

It seems to me that it can dropped as basically "non-atomic and can be

Hi all,
I would like to remind you that the code freeze date for Xen 4.19 is
May 31, 2024.
I'm okay with bug fixes being committed without my release ack (just CC
me), except in cases where a one of maintainers gives a strong NACK.
Have a nice week!

But won't then be confusion that if not generic implementation of
test_bit() is chosen then test_bit() can be " atomic and cannot be
reordered " ( as it is in case of x86 )?

The patch is almost independent from Andrew's patch series
to utilize Clang, it's important to note that,
currently, there is no Xen RISC-V CI job in place to verify the
seamless functioning of the build with Clang.

Changes in V6:
- update the message in README

also disabled for now, as RISC-V hasn't introduced this headers yet.
LIVEPATCH isn't ready for RISC-V too and it can be overriden by randconfig,
so to avoid compilation errors for randconfig it is disabled for now.

The context ("* Find First Set bit. Bits are labelled from 1." in
xen/bitops.h )
suggests there's a dependency on an uncommitted patch. It happens becuase
the current patch
series is based on Andrew's patch series (
htt
$-1,%0\n"
"1:" : "=r" (r) : "rm" (x));
return r + 1;
}
#define arch_fls arch_fls
Any specific reason why 'long' and 'int' types for r are used?

For me it is okay until we don't have Hard Code Release deadline.
