David Hildenbrand	795c230604	riscv/vdso: don't clear PG_reserved The VDSO is part of the kernel image and therefore the struct pages are marked as reserved during boot. As we install a special mapping, the actual struct pages will never be exposed to MM via the page tables. We can therefore leave the pages marked as reserved.

riscv/vdso: don't clear PG_reserved

The VDSO is part of the kernel image and therefore the struct pages are
marked as reserved during boot.

As we install a special mapping, the actual struct pages will never be
exposed to MM via the page tables.  We can therefore leave the pages
marked as reserved.

riscv: remove redundant unlikely()

IS_ERR_VALUE() already implies unlikely(), so it can be omitted.
