[PATCH RFC 01/28] ARM: Prepare includes for generic entry

From: Linus Walleij
Date: Thu Oct 10 2024 - 07:33:58 EST


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.
