Jiri Kosina 6c26fcd2ab x86/speculation/l1tf: Unbreak !__HAVE_ARCH_PFN_MODIFY_ALLOWED architectures
pfn_modify_allowed() and arch_has_pfn_modify_check() are outside of the 
!__ASSEMBLY__ section in include/asm-generic/pgtable.h, which confuses 
assembler on archs that don't have __HAVE_ARCH_PFN_MODIFY_ALLOWED (e.g. 
ia64) and breaks build:

    include/asm-generic/pgtable.h: Assembler messages:
    include/asm-generic/pgtable.h:538: Error: Unknown opcode `static inline bool pfn_modify_allowed(unsigned long pfn,pgprot_t prot)'
    include/asm-generic/pgtable.h:540: Error: Unknown opcode `return true'
    include/asm-generic/pgtable.h:543: Error: Unknown opcode `static inline bool arch_has_pfn_modify_check(void)'
    include/asm-generic/pgtable.h:545: Error: Unknown opcode `return false'
    arch/ia64/kernel/entry.S:69: Error: `mov' does not fit into bundle

Move those two static inlines into the !__ASSEMBLY__ section so that they 
don't confuse the asm build pass.
