The attached patch tweaks the core file support recently committed by
Randolph Chung a bit.  It does two things:

1. Make sure that the .regs pseudo-section is listing after the proc
   sections it's generated from.  This makes things more similar to
   the normal ELF core file support where the .reg pseudo-section is
   listed after the note section it's generated from.

2. Add a .kernel pseudo section.  This will allow Randolph to
   implement proper detection of HP-UX core files by checking the
   contents of this section for the string "HP-UX".

Ok?

Mark

	* elf64-hppa.c (elf64_hppa_section_from_phdr): Create .kernel
	pseudo-section.  Make sure .reg section comes after the proc
	section it's generated from.
