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.
