[PATCH RFC v3 01/30] ARM: Prepare includes for generic entry
From: Linus Walleij <hidden>

Subsystem:
arm port, ptrace support, the rest · Maintainers:
Russell King, Oleg Nesterov, Linus Torvalds
The generic entry code needs a static inline function for regs_irq_disabled() so add this, in further requires the signature of on_thread_stack() to be __always_inline so add this as well.
