Subject: [PATCH RFC v3 01/30] ARM: Prepare includes for generic entry
Date: Tue, 07 Jan 2025 10:41:17 +0100	[thread overview]
Message-ID: <20250107-arm-generic-entry-v3-1-4e5f3c15db2d@linaro.org> (raw)
In-Reply-To: <20250107-arm-generic-entry-v3-0-4e5f3c15db2d@linaro.org>

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.
