Subject: [PATCH 1/2] PCI: Remove __weak annotation from
|
|
pcibios_get_phb_of_node decl
|
|
|
|
The __weak annotation on the pcibios_get_phb_of_node() declaration
|
|
causes *every* definition to be marked "weak." The linker then
|
|
selects one based on link order, which may be the wrong one.
|
|
|
|
Gabor found that on MIPS, the linker selected the generic implementation
|
|
from drivers/pci even though arch/mips supplied a definition without the
|
|
__weak annotation:
|
|
|
|
$ mipsel-openwrt-linux-readelf -s arch/mips/pci/built-in.o \
|
|
drivers/pci/built-in.o vmlinux.o | grep pcibios_get_phb_of_node
|
|
86: 0000046c 12 FUNC WEAK DEFAULT 2 pcibios_get_phb_of_node
|
|
1430: 00012e2c 104 FUNC WEAK DEFAULT 2 pcibios_get_phb_of_node
|
|
31898: 0017e4ec 104 FUNC WEAK DEFAULT 2 pcibios_get_phb_of_node
|
|
|
|
This removes the __weak annotation from the pcibios_get_phb_of_node()
|
|
declaration so arch-specific non-weak implementations work reliably.
