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

76d2a0493a RISC-V: Init and Halt Code 
This contains the various __init C functions, the initial assembly
kernel entry point, and the code to reset the system.  When a file was
init-related this patch contains the entire file.
