While looking at paravirt cleanups I stumbled over slow_down_io() and the related REALLY_SLOW_IO define.Do several cleanups, resulting in a deletion of REALLY_SLOW_IO and the io_delay() paravirt function hook. Patch 4 is removing the config options for selecting the default delay mechanism and sets the default to "no delay". This is in preparation of removing the io_delay() functionality completely, as suggested by Ingo Molnar. Patch 5 is adding an additional config option allowing to avoid building io_delay.c (default is still to build it). Changes in V2: - patches 2 and 3 of V1 have been applied - new patches 4 and 5 Juergen Gross (5): x86/paravirt: Replace io_delay() hook with a bool block/floppy: Don't use REALLY_SLOW_IO for delays x86/io: Remove REALLY_SLOW_IO handling x86/io_delay: Switch io_delay() default mechanism to "none" x86/io_delay: Add config option for controlling build of io_delay. arch/x86/Kconfig | 8 +++ arch/x86/Kconfig.debug | 30 ---------- arch/x86/include/asm/floppy.h | 31 ++++++++-- arch/x86/include/asm/io.h | 17 +++--- arch/x86/include/asm/paravirt.h | 11 +--- arch/x86/include/asm/paravirt_types.h | 3 +- arch/x86/kernel/Makefile | 3 +- arch/x86/kernel/cpu/vmware.c | 2 +- arch/x86/kernel/io_delay.c | 81 +-------------------------- arch/x86/kernel/kvm.c | 8 +-- arch/x86/kernel/paravirt.c | 3 +- arch/x86/kernel/setup.c | 4 +- arch/x86/xen/enlighten_pv.c | 6 +- drivers/block/floppy.c | 2 - 14 files changed, 55 insertions(+), 154 deletions(-)
