Description of changes:

[1.28-1]
- Build new dwarves release, depends on libbpf-devel v1.5 [Orabug: 37277258]

[1.27-2]
- Backport upstream bugfixes for clang builds
  Resolves: RHEL-54022

[1.27-1]
- Resolves: RHEL-30780
- New release: v1.26
- When expanding types using 'pahole -E' do it for union and struct typedefs and for enums too.
- Print number of holes, bit holes and bit paddings in class member types.
- Introduce --contains_enumerator=ENUMERATOR_NAME:
- Fix pretty printing using DWARF, waiting for a CU with both class (-C) and a specified "type_enum".
- Add support for DW_TAG_constant in the DWARF loader, first seen in Go DWARF.
- Fix loading DW_TAG_subroutine_type generated by the Go compiler.
- Fix loading of 32-bit signed enums from BTF.
- Add 'pahole --btf_features' to allow consumers to specify an opt-in set of features they want to use in BTF encoding.
- Parallelize loading BTF and DWARF, speeding up a bit btfdiff.
- Do type expansion to cover "private" types and enumerations in btfdiff.
- New release: v1.27
- Reproducible parallel builds: multiple runs with different number of loading/encoding threads produce the same result.
- Inject kfunc decl tags into BTF from the BTF IDs ELF section in the Linux kernel vmlinux file.
- Sanitize unsupported DWARF int type with greater-than-16 byte, as BTF doesn't support it.
- Initial support for BTF_KIND_DECL_TAG in the BTF loader, adding support in pfunct output.
- Fix hole discovery with inheritance in C++.

[1.25-1]
- Resolves: rhbz#2190484
- Build with system libbpf
- New release: v1.25
- Support for DW_TAG_unspecified_type more generally.
- Make sure struct member offsets are in ascending order. Rust BTF needs this.
- Support C atomic types (DW_TAG_atomic_type).
- Initial support for DW_TAG_LLVM_annotation, used for BTF type tags, for __rcu, __user, etc
- Exclude functions with the same name (static functions in different CUs), inconsistent prototypes or not following calling convention.
- Allow generation of BTF for optimized functions, those that end with a .isra*, .constprop*.
- Support 'pahole --lang=/--lang_exclude=asm'
- Support --compile from DWARF in addition to from BTF.
- Exclude RUST CUs in 'btfdiff', as those are not yet being BTF encoded.
