Subject: kgdb: Remove "weak" from kgdb_arch_pc() declaration
From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>
commit 107bcc6d566cb40184068d888637f9aefe6252dd upstream.
kernel/debug/debug_core.c provides a default kgdb_arch_pc() definition
explicitly marked "weak". Several architectures provide their own
definitions intended to override the default, but the "weak" attribute on
the declaration applied to the arch definitions as well, so the linker
chose one based on link order (see 10629d711ed7 ("PCI: Remove __weak
annotation from pcibios_get_phb_of_node decl")).
Remove the "weak" attribute from the declaration so we always prefer a
non-weak definition over the weak one, independent of link order.
Fixes: 688b744d8bc8 ("kgdb: fix signedness mixmatches, add statics, add declaration to header")
