kvm: provide kvm.h for all architecture: fixes headers_install

2008-04-02T22:28:18Z

Currently include/linux/kvm.h is not considered by make headers_install, because Kbuild cannot handle " unifdef-$(CONFIG_FOO) += foo.h. This problem was introduced by commit fb56dbb31c4738a3918db81fd24da732ce3b4ae6 Author: Avi Kivity Date: Sun Dec 2 10:50:06 2007 +0200 KVM: Export include/linux/kvm.h only if $ARCH actually supports KVM Currently, make headers_check barfs due to , which includes, not existing. Rather than add a zillion s, export kvm. only if the arch actually supports it. Signed-off-by: Avi Kivity which makes this an 2.6.25 regression. One way of solving the issue is to enhance Kbuild, but Avi and David conviced me, that changing headers_install is not the way to go. This patch changes the definition for linux/kvm.h to unifdef-y. If unifdef-y is used for linux/kvm.h "make headers_check" will fail on all architectures without asm/kvm.h. Therefore, this patch also provides asm/kvm.h on all architectures.

remove include/asm-sh/floppy.h

This patch removes the unused include/asm-sh/floppy.h (ARCH_MAY_HAVE_PC_FDC was not enabled). Signed-off-by: Adrian Bunk Signed-off-by: Paul Mundt

sh: Fix TIF_USEDFPU clearing under FPU emulation.

2008-03-26T10:09:21Z

The unlazy_fpu() path calls in to save_fpu() if the task has TIF_USEDFPU set. save_fpu() being the crap API that it is has the side effect of clearing the flag itself, which presently doesn't happen if we're using FPU emulation. Fix this up for now, pending an overhaul in 2.6.26. Signed-off-by: Paul Mundt

sh: Fix occasional FPU register corruption under preempt.

2008-03-26T10:02:47Z

Presently with preempt enabled there's the possibility to be preempted after the TIF_USEDFPU test and the register save, leading to bogus state post-__switch_to(). Use an explicit preempt_disable()/enable() pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86 change. Reported-by: Takuo Koguchi Signed-off-by: Paul Mundt

sh: Fix more user header breakage from sh64 integration.

2008-03-14T08:21:09Z

posix_types.h and byteorder.h were sticking purely with the Kconfig symbols, which doesn't work when we scrub the headers for user use. Fixes a very unhelpful build error in current klibc. Signed-off-by: Paul Mundt

sh: Fix up the sh64 build.

serial: Move asm-sh/sci.h to linux/serial_sci.h.

2008-02-26T05:52:45Z

This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead. This should get h8300 working again for 2.6.25, in addition to the changes already pushed by Sato-san in -rc2. Signed-off-by: Paul Mundt

sh: fix ioreadN_rep and iowriteN_rep

2008-02-14T05:25:37Z

This patch is a fix to make sure readsN/writesN are used over insN/outsN for ioreadN_rep/iowriteN_rep. The current state of the sh io code is that mmio operations like readN/writeN and ioreadN/iowriteN are unaffected by the value of generic_io_base. This is different fom port based io like inN/outN which gets adjusted using the value in generic_io_base. Without this patch ioreadN_rep/iowriteN_rep get their addresses adjusted. The address for mmio access is adjusted using generic_io_base. This is wrong. The ata core code currently crashes if generic_io_base is set. This patch changes ioreadN_rep/iowriteN_rep to follow the same rules as the rest of the mmio operations, ie don't adjust using generic_io_base.
