these two patches convert the s390 architecture to generic VDSO. The
first patch adds an option to add architecture specific information
to struct vdso_data. We need that information because the old s390
assembly code had a steering capability, which steered the clock slowly.
To emulate that
This patch converts s390 to the generic vDSO. There are a few special
things on s390:
- vDSO can be called without a stack frame - glibc did this in the past.
So we need to allocate a stackframe on our own.
- The former assembly code used stcke to get the TOD clock and applied
time steering
Add the possibility to add architecture specific vDSO
data to struct vdso_data. This is useful if the arch specific
user space VDSO code needs additional data during execution.
If CONFIG_ARCH_HAS_VDSO_DATA is defined, the generic code will
include asm/vdso/data.h which should contain 'struct
