x86: make TASK_SIZE_MAX usable from assembly code
For 64-bit the only thing missing was a strategic _AC, and for 32-bit we need to use __PAGE_OFFSET instead of PAGE_OFFSET in the TASK_SIZE definition to escape the explicit unsigned long cast. This just works because __PAGE_OFFSET is defined using _AC itself and thus never needs the cast anyway. Signed-off-by:Christoph Hellwig <hch@lst.de> Reviewed-by:
