Subject: [PATCH 0/3] riscv: vdso.lds.S: some improvement

This series renews one of my last year RFC patch[1], tries to improve
the vdso layout a bit. 

patch1 removes useless symbols
patch2 merges .data section of vdso into .rodata because they are
readonly
patch3 is the real renew patch, it removes hardcoded 0x800 .text start
addr. But I rewrite the commit msg per Andrew's suggestions and move
move .note, .eh_frame_hdr, and .eh_frame between .rodata and .text to
keep the actual code well away from the non-instruction data.
