Fix by including the appropriate header files in the appropriate
source files.
This patch should have no functional impact.

Several functions and arrays which are only used in the files in which
they are declared are missing "static" qualifiers. Warnings for these
symbols are reported by sparse:
arch/riscv/kernel/vdso.c:28:18: warning: symbol 'vdso_data' was not declared. Should it be static?
arch/riscv/mm/sifive_l2_cache.c:145:12: warning: symbol 'sifive_l2_init' was not declared. Should it be static?
Resolve these warnings by marking them as static.

Since commit a6c19dfe39 ("arm64,ia64,ppc,s390,sh,tile,um,x86,mm:
remove default gate area"), which predates riscv's inclusion in
Linux by almost three years, the default behavior wrt the gate area
is sane. Remove riscv's gate area stubs.

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.

This contains the various __init C functions, the initial assembly
