UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k)
The m68k arch doesn't have a kvm_para.h (unlike most or maybe all other arches), but there is one in asm-generic. This means that: ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \ $(srctree)/include/asm-$(SRCARCH)/kvm_para.h \ $(INSTALL_HDR_PATH)/include/asm-*/kvm_para.h),) header-y += kvm_para.h endif gets it wrong because it is invoked twice during the header installation - and on the second occasion, asm-generic/kvm_para.h has been installed in usr/, thus triggering a attempt to install asm-m68k/kvm_para.h which will fail. There are three headers with this sort of conditional logic: a.out.h, kvm.h and kvm_para.h. For all three of them, change the logic to be something like: ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \ $(srctree)/arch/$(SRCARCH)/include/uapi/asm/kvm_para.h),) which finds the header in only the two places it should be found, and doesn't get incorrectly triggered by the installation of asm-generic's version.
