1e18ffc991 bpf: include, bfd, opcodes: add EF_BPF_CPUVER ELF header flags
This patch adds support for EF_BPF_CPUVER bits in the ELF
machine-dependent header flags.  These bits encode the BPF CPU
version for which the object file has been compiled for.

The BPF assembler is updated so it annotates the object files it
generates with these bits.

The BPF disassembler is updated so it honors EF_BPF_CPUVER to use the
appropriate ISA version if the user didn't specify an explicit ISA
version in the command line.  Note that a value of zero in
EF_BPF_CPUVER is interpreted by the disassembler as "use the later
supported version" (the BPF CPU versions start with v1.)

The readelf utility is updated to pretty print EF_BPF_CPUVER when it
prints out the ELF header:

   $ readelf -h a.out
   ELF Header:
     ...
     Flags:                             0x4, CPU Version: 4

Tested in bpf-unknown-none.

5e24da908d PR30592 objcopy: allow --set-section-flags to add or remove SHF_X86_64_LARGE
For example, objcopy --set-section-flags .data=alloc,large will add
SHF_X86_64_LARGE to the .data section.  Omitting "large" will drop the
SHF_X86_64_LARGE flag.

The bfd_section flag is named generically, SEC_ELF_LARGE, in case other
processors want to follow SHF_X86_64_LARGE.  SEC_ELF_LARGE has the same
value as SEC_TIC54X_BLOCK used by coff.

93c8054387 Add full display feature to dwarf-mode.el
I've found that I often use dwarf-mode with relatively small test
files.  In this situation, it's handy to be able to expand all the
DWARF, rather than moving to each "..." separately and using C-u C-m.

This patch implements this feature.  It also makes a couple of other
minor changes:

* I removed a stale FIXME from dwarf-mode.  In practice I find I often
  use "g" to restore the buffer to a pristine state; checking the file
  mtime would work against this.

* I tightened the regexp in dwarf-insert-substructure.  This prevents
  the C-m binding from trying to re-read a DIE which has already been
  expanded.

* Finally, I've bumped the dwarf-mode version number so that this
  version can easily be installed using package.el.

	* dwarf-mode.el: Bump version to 1.8.
	(dwarf-insert-substructure): Tighten regexp.
	(dwarf-refresh-all): New defun.
	(dwarf-mode-map): Bind "A" to dwarf-refresh-all.
	(dwarf-mode): Remove old FIXME.
