Subject: [PATCH 2/3] hexagon: Use common DISCARDS macro
Date: Thu, 20 May 2021 18:12:38 -0700 [thread overview]
Message-ID: <20210521011239.1332345-3-nathan@kernel.org> (raw)
In-Reply-To: <20210521011239.1332345-1-nathan@kernel.org>
ld.lld warns that the '.modinfo' section is not currently handled:
ld.lld: warning: kernel/built-in.a(workqueue.o):(.modinfo) is being placed in '.modinfo'
ld.lld: warning: kernel/built-in.a(printk/printk.o):(.modinfo) is being placed in '.modinfo'
ld.lld: warning: kernel/built-in.a(irq/spurious.o):(.modinfo) is being placed in '.modinfo'
ld.lld: warning: kernel/built-in.a(rcu/update.o):(.modinfo) is being placed in '.modinfo'
The '.modinfo' section was added in commit 898490c010b5 ("moduleparam:
Save information about built-in modules in separate file") to the
DISCARDS macro but Hexagon has never used that macro. The unification of
DISCARDS happened in commit 023bf6f1b8bf ("linker script: unify usage of
discard definition") in 2009, prior to Hexagon being added in 2011.
Switch Hexagon over to the DISCARDS macro so that anything that is
expected to be discarded gets discarded.
Fixes: e95bf452a9e2 ("Hexagon: Add configuration and makefiles for the Hexagon architecture.")
