pata_cs5536: avoid implicit MSR API inclusion on x86-64
We don't need or want MSR usage here, on x86-64. x86-64 was disabled intentionally in Kconfig, but commit 9272dcc232b84ccb027d6861077934055d42764d changed that. drivers/ata/pata_cs5536.c:47:1: warning: "rdmsr" redefined In file included from arch/x86/include/asm/irqflags.h:60, from include/linux/irqflags.h:15, from arch/x86/include/asm/system.h:11, from arch/x86/include/asm/processor.h:17, from include/linux/prefetch.h:14, from include/linux/list.h:7, from include/linux/module.h:9, from drivers/ata/pata_cs5536.c:33: arch/x86/include/asm/paravirt.h:146:1: warning: this is the location of the previous definition drivers/ata/pata_cs5536.c:48:1: warning: "wrmsr" redefined arch/x86/include/asm/paravirt.h:154:1: warning: this is the location of the previous definition Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
