x86/speculation/l1tf: Unbreak !__HAVE_ARCH_PFN_MODIFY_ALLOWED architectures
commit 6c26fcd2abfe0a56bbd95271fce02df2896cfd24 upstream.
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.
