[PATCH] RISC-V: fixup in-flight collision with ARCH_WANT_OPTIMIZE_VMEMMAP rename

[PATCH] RISC-V: fixup in-flight collision with ARCH_WANT_OPTIMIZE_VMEMMAP rename

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

Lukas warned that ARCH_WANT_HUGETLB_PAGE_OPTIMIZE_VMEMMAP had been
renamed in the mm tree & that RISC-V would need a fixup as part of the
merge. The warning was missed however, and RISC-V is selecting the
orphaned Kconfig option.

That should have been Lukas Bulwahn <lukas.bulwahn@gmail.com>.
This is what I get for hand-typing an email address that I could have
copied from lore I suppose.

Indeed, you have a newer version of b4 without also updating the patatt dependency. If you're using b4 from git, you need to "git submodule update".

Thanks, it's fixed.  This one's in the queue for testing, but it looks 
generally fine.  Might be a bit slower than usual, as I'm also running 
the glibc tests.

I think I got that right, but the email bounced.  I'm not sure if it's 
just the list issues, though.

B4 probably just replied to the address in my original email,
rather than the corrected one?
