Subject: [PATCH] vmlinux.lds: fix .data..init_task output section (fix
popwerpc boot)

The .data..init_task output section was missing
a load offset causing a popwerpc target to fail to boot.

Sean MacLennan tracked it down to the definition of
INIT_TASK_DATA_SECTION().

There are only two users of INIT_TASK_DATA_SECTION()
in the kernel today: cris and popwerpc.
cris do not support relocatable kernels and is thus not
impacted by this change.

Fix INIT_TASK_DATA_SECTION() to specify load offset like
all other output sections.
