rc4-rt1: powerpc compile errors

[Pradyumna Sampath]

Hi everyone,

Here are some compile errors from the latest -rt patchset for powerpc
(mpc5200).

arch/powerpc/kernel/entry_32.S: Assembler messages:
arch/powerpc/kernel/entry_32.S:231: Error: operand out of range
(0x00023d87 is not between 0x00000000 and 0x0000ffff)
arch/powerpc/kernel/entry_32.S:644: Error: operand out of range
(0x00022006 is not between 0x00000000 and 0x0000ffff)
arch/powerpc/kernel/entry_32.S:866: Error: operand out of range
(0x00020004 is not between 0x00000000 and 0x0000ffff)
arch/powerpc/kernel/entry_32.S:880: Error: operand out of range
(0x00020004 is not between 0x00000000 and 0x0000ffff)

Im not sure whether this is the right thing to do but we got around
this by replacing the linux/include/asm-powerpc/thread_info.h with an
older version of the same file from 2.6.21-rt3.

I don't have the code in front of me, but you can also shuffle
the flags to make sure that macro being used in entry_32.S
has all the flags within 16 bits (so the immediate operations
will successfully assemble). That's the route I took. The flags
have expanded past that threshold just recently.
