Subject: [PATCH 3/3] ARM: omap2: move platform-specific asm-offset.h to arch/arm/mach-omap2
Date: Mon,  8 Apr 2019 16:54:27 +0900	[thread overview]
Message-ID: <20190408075427.6052-3-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <20190408075427.6052-1-yamada.masahiro@socionext.com>

<generated/ti-pm-asm-offsets.h> is only generated and included
by arch/arm/mach-omap2/, so it does not need to reside in the
globally visible include/generated/.

I moved and renamed it to arch/arm/mach-omap2/pm-asm-offsets.h
since the prefix 'omap2-' is just redundant in mach-omap2/.

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Can this be applied to ARM-SOC tree in a series?
(with Ack from the platform sub-maintainer.)

ti-pm-asm-offsets.h does not need to reside in include/generated/,
but you may ask "Why must it get out of include/generated/?"

My main motivation is to avoid a race condition in the currently
proposed patch:

https://lore.kernel.org/patchwork/patch/1052763/

This patch tries to embed some build artifacts into the kernel.

If arch/arm/mach-omap2/ and kernel/ are built at the same time,
it may embed a truncated file.
