[PATCH v2 mips-next 0/4] MIPS: vmlinux.lds.S sections fix & cleanup

[Alexander Lobakin]

This series hunts the problems discovered after manual enabling of
ARCH_WANT_LD_ORPHAN_WARN, notably the missing PAGE_ALIGNED_DATA()
section affecting VDSO placement (marked for stable).

Compile and runtime tested on MIPS32R2 CPS board with no issues.

Since v1 [0]:
 - catch .got entries too as LLD may produce it (Nathan);
 - check for unwanted sections to be zero-sized instead of
   discarding (Fangrui).
