MIPS: kernel: Fix random segmentation faults
[ Upstream commit 14b46ba92bf547508b4a49370c99aba76cb53b53 ]
Commit 69896119dc9d ("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.
