bfa: deinline __bfa_trc() and __bfa_trc32()
__bfa_trc() compiles to 115 bytes of machine code. With this .config: http://busybox.net/~vda/kernel_config there are 1494 calls of __bfa_trc(). __bfa_trc32() is very similar, so it is uninlined too. However, it appears to be unused, therefore this patch ifdefs it out. Change in code size is about 130,000 bytes: text data bss dec hex filename 85975426 22294712 20627456 128897594 7aed23a vmlinux.before 85842882 22294584 20627456 128764922 7accbfa vmlinux [mkp: Removed unused __bfa_trc32()] Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com> Acked-by: Anil Gurumurthy <anil.gurumurthy@qlogic.com> CC: Fabian Frederick <fabf@skynet.be> CC: Anil Gurumurthy <anil.gurumurthy@qlogic.com> CC: Christoph Hellwig <hch@lst.de> CC: Guenter Roeck <linux@roeck-us.net> CC: Ben Hutchings <ben@decadent.org.uk> CC: James Bottomley <JBottomley@Parallels.com> CC: linux-kernel@vger.kernel.org CC: linux-scsi@vger.kernel.org Signed-off-by: Martin K.
