Michael Ellerman 11df1f0551 PCI/MSI: Use #ifdefs instead of weak functions ... Weak functions aren't all they're cracked up to be. They lead to incorrect binaries with some toolchains, they require us to have empty functions we otherwise wouldn't, and the unused code is not elided (as of gcc 4.3.2 anyway). So replace the weak MSI arch hooks with the #define foo foo idiom. We no longer need empty versions of arch_setup/teardown_msi_irq(). This is less source (by 1 line!), and results in smaller binaries too: text data bss dec hex filename 9354300 1693916 678424 11726640 b2ef30 build/powerpc/vmlinux-before 9354052 1693852 678424 11726328 b2edf8 build/powerpc/vmlinux-after Also smaller on x86_64 and arm (iop13xx).
