This was found by inspection while tracking a similar
bug in compat_statfs64, that has been fixed in mainline
since decemeber.
- This fixes a bug where not all of the f_spare fields
were cleared on mips and s390.
- Add the f_flags field to struct compat_statfs
- Copy f_flags to userspace in case someone cares.
- Use __clear_user to copy the f_spare field to userspace
to ensure that all of the elements of f_spare are cleared.
On some architectures f_spare is has 5 ints and on some
architectures f_spare only has 4 ints. Which makes
the previous technique of clearing each int individually
broken.
I don't expect anyone actually uses the old statfs system
call anymore but if they do let them benefit from having
the compat and the native version working the same.

Standarize and document the FPGA nodes used on Freescale QorIQ reference
boards. There are different kinds of FPGAs used on the boards, but
only two are currently standard: "pixis", "ngpixis", and "qixis". Although
there are minor differences among the boards that have one kind of FPGA, most
of the functionality is the same, so it makes sense to create common
compatibility strings.
We also need to update the P1022DS platform file, because the compatible
string for its PIXIS node has changed. This means that older kernels are
not compatible with newer device trees. This is not a real problem, however,
since that particular function doesn't work anyway. When the DIU is active,
the PIXIS is in "indirect mode", and so cannot be accessed as a memory-mapped
device.

On FSL Book-E devices we support multiple large TLB sizes and so we can
get into situations in which the initial 1G TLB size is too big and
we're asked for a size that is not mappable by a single entry (like
512M). The single entry is important because when we bring up secondary
cores they need to ensure any data structure they need to access (eg
PACA or stack) is always mapped.
So we really need to determine what size will actually be mapped by the
first TLB entry to ensure we limit early memory references to that
region. We refactor the map_mem_in_cams() code to provider a helper
function that we can utilize to determine the size of the first TLB
entry while taking into account size and alignment constraints.

For those MMUs that have some form of bolt'd linear mapping (TLB)
required its rare that one ever sets mem= smaller than the size of that
mapping.
However, on Book-E 64 parts the initial linear mapping is quite large
(1G) so its quite reasonable that mem= is set smaller than that.
We need to parse the command line for mem= limit and constrain the
amount of memory we map initially by it if need be.
