Dave Hansen 8245525741 maps4: rework TASK_SIZE macros ... The following replaces the earlier patches sent. It should address David Rientjes's comments, and has been compile tested on all the architectures that it touches, save for parisc. For the /proc/<pid>/pagemap code[1], we need to able to query how much virtual address space a particular task has. The trick is that we do it through /proc and can't use TASK_SIZE since it references "current" on some arches. The process opening the /proc file might be a 32-bit process opening a 64-bit process's pagemap file. x86_64 already has a TASK_SIZE_OF() macro: #define TASK_SIZE_OF(child) ((test_tsk_thread_flag(child, TIF_IA32)) ? IA32_PAGE_OFFSET : TASK_SIZE64) I'd like to have that for other architectures. So, add it for all the architectures that actually use "current" in their TASK_SIZE. For the others, just add a quick #define in sched.h to use plain old TASK_SIZE. 1. http://www.linuxworld.com/news/2007/042407-kernel.html - MIPS portion from Ralf Baechle <ralf@linux-mips.org> [akpm@linux-foundation.org: fix mips build] Signed-off-by: Dave Hansen <haveblue@us.ibm.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Matt Mackall <mpm@selenic.com> Acked-by: David Rientjes <rientjes@google.com> Cc: Dave Hansen <haveblue@us.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2008-02-05 09:44:16 -08:00
