This patchset removes three unreferenced and unused header files of the ia64
architecture. Also some #include directives would resolve to the files I propose
for removal, the dependencies defined by kconfig for those files do not allow
their usage together with ia64.
I detected the issue with chimaera, a tool I currently develop for my bachelor
thesis extending the undertaker tool suite to take the relation of files based
on #include directives into account (https://undertaker.cs.fau.de).

From: Jonas Rabenstein <[email protected]>
The file arch/ia64/include/asm/mc146818rtc.h is not used anymore. It
would be included by include/linuxmc146818rtc.h which in fact is
included by the following files:
* sound/core/rtctimer.c:
depends on SND_RTCTIMER -> RTC -> !IA64
* drivers/char/nvram.c:
depends on NVRAM -> X86
* drivers/char/rtc.c:
depends on RTC -> !IA64
* drivers/block/floppy.c:
depends on BLK_DEV_FD -> ARCH_MAY_HAVE_PC_FDC (not defined for IA64)
* drivers/firmware/dcdbas.c:
depends on DCDBAS -> X86
* include/asm/generic/rtc.h:
- drivers/rtc/rtc-cmos.c
depends on RTC_DRV_CMOS -> (X86||ARM||M32R||PPC||MIPS||SPARC64)
- drivers/acpi/acpi/acpi_cmos_rtc.c:
depends on X86
- drivers/rtc/rtc/mrst.c:
depends on RTC_DRV_VRTC -> X86_INTEL_MID (not defined for IA64)
* drivers/char/mwave/smapi.c
depends on MWAVE -> X86
* drivers/input/misc/wistron_btns.c:
depends on CONFIG_WISTRON_BTNS -> X86_32
* drivers/scsi/gdth.c
depends on SCSI_GDTH -> ISA_DMA_API (not defined for IA64)

From: Jonas Rabenstein <[email protected]>
The file arch/ia64/include/asm/segment.h contains only a comment that it
is still in the source tree as it may be referenced from some files.
Actually only 2 files that are not in an arch/* directory include
<asm/segment.h>.
The first is drivers/lguest/x86/switcher_32.S and obviously is not used
by ia64.
The second is include/asm-generic/uacess.h and also not used by ia64.

From: Jonas Rabenstein <[email protected]>
The file arch/ia64/include/asm/idle.h can not be included by any file
and as a consequence may be removed from the source tree.
Currently five files have #includes for asm/idle.h:
drivers/cpufreq/loongson2_cpufreq.c:
depends on LOONGSON2 (mips)
drivers/cpuidle/cpuidle-cps.c:
depends on MIPS_CPS_CPUIDLE (mips)
drivers/idle/i7300_idle.c:
depends on X86_64
drivers/thermal/intel_powerclamp.c:
depends on X86
drivers/xen/events/events_base.c:
depends on XEN (arm/x86)
