Make THREAD_SIZE available to vmlinux.lds on hexagon by including
asm/thread_info.h the linker script.

This allows init_stack to be allocated in the linker script in a subsequent

nmi_backtrace: generate one-line reports for idle cpus 2016-10-08T01:46:30+00:00 Chris Metcalf cmetcalf@mellanox.com 2016-10-08T00:02:55+00:00 6727ad9e206cc08b80d8000a4d67f8417e53539d When doing an nmi backtrace of many cores, most of which are idle, the output is a little overwhelming and very uninformative. Suppress messages for cpus that are idling when they are interrupted and just emit one line, "NMI backtrace for N skipped: idling at pc 0xNNN". We do this by grouping all the cpuidle code together into a new .cpuidle.text section, and then checking the address of the interrupted PC to see if it lies within that section. This commit suitably tags x86 and tile idle routines, and only adds in the minimal framework for other architectures.
