Due to a different size of ino_t ustat needs a compat handler, but
currently only x86 and mips provide one. Add a generic compat_sys_ustat
and switch all architectures over to it. Instead of doing various
user copy hacks compat_sys_ustat just reimplements sys_ustat as
it's trivial. This was suggested by Arnd Bergmann.

Supported are Ethernet, serial console, I2C, I2C-based RTC and
temperature sensors, NOR and NAND flash, PCI, USB, CAN and Lime
display controller.
The multiplexing of FPGA interrupts onto PowerPC interrupt lines is
supported through our own fpga_pic interrupt controller driver.
For example the SJA1000 controller is level low sensitive connected to
fpga_pic line 2 and is routed to the second (of three) irq lines to
the CPU:
can@3,100 {
compatible = "philips,sja1000";
reg = <3 0x100 0x80>;
interrupts = <2 2>;
interrupts = <2 8 1>; // number, type, routing
interrupt-parent = <&fpga_pic>;
};

To fix this problem, check ->mm instead of ->active_mm, and this
means:

On powerpc64 machines running 32-bit userspace, we can get garbage bits in the
stack pointer passed into the kernel. Most places handle this correctly, but
the signal handling code uses the passed value directly for allocating signal
stack frames.
This fixes the issue by introducing a get_clean_sp function that returns a
sanitized stack pointer. For 32-bit tasks on a 64-bit kernel, the stack
pointer is masked correctly. In all other cases, the stack pointer is simply
returned.
Additionally, we pass an 'is_32' parameter to get_sigframe now in order to
get the properly sanitized stack. The callers are know to be 32 or 64-bit
statically.
