x86/tdx: mark tdh_vp_enter() as __flatten
In some cases tdx_tdvpr_pa() is not fully inlined into tdh_vp_enter(), which causes the following warning: vmlinux.o: warning: objtool: tdh_vp_enter+0x8: call to tdx_tdvpr_pa() leaves .noinstr.text section This happens if the compiler considers tdx_tdvpr_pa() to be "large", for example because CONFIG_SPARSEMEM adds two function calls to page_to_section() and __section_mem_map_addr(): ({ const struct page *__pg = (pg); \ int __sec = page_to_section(__pg); \ (unsigned long)(__pg - __section_mem_map_addr(__nr_to_section(__sec))); \ }) Because exiting the noinstr section is a no-no, just mark tdh_vp_enter() for full inlining.
