[PATCH -resend 26/27] x86_32: assembly, change all ENTRY+ENDPROC to SYM_FUNC_*

From: Jiri Slaby <hidden>
Date: 2018-05-10 08:08:12
Also in: linux-crypto, linux-efi, lkml
Subsystem: extensible firmware interface (efi), the rest, x86 architecture (32-bit and 64-bit), x86 entry code · Maintainers: Ard Biesheuvel, Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen, Andy Lutomirski 

These are all functions which are invoked from elsewhere, so we annotate
them as global using the new SYM_FUNC_START (and their ENDPROC's by
SYM_FUNC_END.)

Now, we can finally force ENTRY/ENDPROC to be undefined on X86.
