[PATCH 0/2] tools/kexec: Introduce utility to build zboot image with bpf section

[Pingfan Liu]

The series '[PATCHv3 0/9] kexec: Use BPF lskel to enable kexec to load PE
format boot image' [1] makes the kernel ready to load PE files with .bpf
sections. These two patches integrate the zboot-bpf image builder into
the kernel source tree, so users can conveniently generate the final image
with the command:
    make -C tools/kexec zboot
Later, the infrastructure for UKI can also be organized here.

To facilitate the review, I have pushed the whole series, including the kernel part,
to GitHub [2]. There is a slight difference from [PATCHv3 8/9] 
"kexec: Integrate bpf light skeleton to load zboot image" in [1]. This
difference is made in the function get_symbol_from_elf() to accommodate
clang's behavior, which combines the section header string table and normal
string table into one.
