Subject: x86_64 vDSO linker script cleanup
From: Roland McGrath <roland@xxxxxxxxxx>
I can't see the reason ". = VDSO_PRELINK + 0x900;" was ever there in the
linker script for the x86_64 vDSO. I can't find anything that depends on this
magic offset, or that should care at all about the particular location of of
the .data section (all from vvar.c) in the vDSO image. If it is really
desireable to place .data at 0x900, then it should be after all the other
sections so they fill in the space up to 0x900.
This removes the 0x900 magic and cleans up the output sections generally in
the vDSO linker script. This saves a few hundred bytes in the size of the
vDSO file, bringing it back well under 4kb total so that its vma only needs
one page.
