    ARM: Prepare for randomized task_struct · ffa47aa6
    Arnd Bergmann authored
    With the new task struct randomization, we can run into a build
    failure for certain random seeds, which will place fields beyond
    the allow immediate size in the assembly:
    
    arch/arm/kernel/entry-armv.S: Assembler messages:
    arch/arm/kernel/entry-armv.S:803: Error: bad immediate value for offset (4096)
    
    Only two constants in asm-offset.h are affected, and I'm changing
    both of them here to work correctly in all configurations.
    
    One more macro has the problem, but is currently unused, so this
    removes it instead of adding complexity.
