[ Upstream commit681ba73c72] 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 commit898490c010("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 commit023bf6f1b8("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.
