Fix conditional export of kvh.h and a.out.h to userspace.

2008-09-05T14:44:31Z

Some architectures have moved the asm/ into arch/ and some have not. This patch checks for a.out.h and kvh.h in both places before exporting the corresponding file from linux/ [dwmw2: simplified a little] Signed-off-by: Khem Raj Signed-off-by: David Woodhouse

remove dummy asm/kvm.h files

2008-07-25T18:35:50Z

This patch removes the dummy asm/kvm.h files on architectures not (yet) supporting KVM and uses the same conditional headers installation as already used for a.out.h . Also removed are superfluous install rules in the s390 and x86 Kbuild files (they are already in Kbuild.asm). Signed-off-by: Adrian Bunk Acked-by: Sam Ravnborg Signed-off-by: David Woodhouse

kbuild: fix a.out.h export to userspace with O= build.

2008-06-27T21:13:54Z

We need to check for existence of the a.out.h header in the source tree, not the object tree, if we want it to get the right answer with O=. Signed-off-by: David Woodhouse Signed-off-by: Sam Ravnborg

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.

aout: suppress A.OUT library support if !CONFIG_ARCH_SUPPORTS_AOUT

2008-02-08T17:22:30Z

Suppress A.OUT library support if CONFIG_ARCH_SUPPORTS_AOUT is not set. Not all architectures support the A.OUT binfmt, so the ELF binfmt should not be permitted to go looking for A.OUT libraries to load in such a case. Not only that, but under such conditions A.OUT core dumps are not produced either. To make this work, this patch also does the following: (1) Makes the existence of the contents of linux/a.out.h contingent on CONFIG_ARCH_SUPPORTS_AOUT. (2) Renames dump_thread() to aout_dump_thread() as it's only called by A.OUT core dumping code. (3) Moves aout_dump_thread() into asm/a.out-core.h and makes it inline. This is then included only where needed. This means that this bit of arch code will be stored in the appropriate A.OUT binfmt module rather than the core kernel. (4) Drops A.OUT support for Blackfin (according to Mike Frysinger it's not needed) and FRV. This patch depends on the previous patch to move STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as they're required whether or not A.OUT format is available.
