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

From: Conor Dooley <conor.dooley@...rochip.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.

Fixes: 89d77f71f493 ("Merge tag 'riscv-for-linus-6.4-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux")
