Thomas Bogendoerfer 14b46ba92b MIPS: kernel: Fix random segmentation faults 
Commit 69896119dc ("MIPS: vdso: Switch to generic storage
implementation") switches to a generic vdso storage, which increases
the number of data pages from 1 to 4. But there is only one page
reserved, which causes segementation faults depending where the VDSO
area is randomized to. To fix this use the same size of reservation
and allocation of the VDSO data pages.

Fixes: 69896119dc ("MIPS: vdso: Switch to generic storage implementation")
