- Upgrade to version 5.4
Drop patch: rawhide-6.13-kbuild-compatibility.patch (upstream)
Drop patch: linux-6.13-fedora-compatibility.patch (upstream)
Add patch: elaborate.cxx-fix-32-bit-build.patch (resolve 32-bit build error)
Add patch: guard-usage-of-vmlinux.h.patch (temporary fix)
Drop explicit packaging of /var/cache/systemtap (jsc#PED-14770)
Summary of changes (v5.4):
- The kernel-context @cast operator now implicitly searches a kernel's
<vmlinux.h> generated header file first, if available (kernel 5.7+),
for type declarations. This can make some debuginfo access
unnecessary, and thus processing faster. It can work around kernel
API changes where type declarations move between headers.
Use --compatible=5.3 to disable this behaviour.
Use @cast(..., "kernel<vmlinux.h>") manually if desired.
- Type checking and autocast processing have been made more thorough,
so elided variables are checked more and @defined() tests may be
more complicated. Preexisting scripts that rely on elision for
bypassing type violations may now get caught. No --compatible
option exists to suppress this new behaviour.
- The sys/sdt.h file now arranges to include the section flag "R"
(RETAIN) for the .stapsdt.base elf sections related to sdt markers,
for compatibility with aggressive GC operations in some linkers.
- Kernel portability changes
- The dropwatch.stp [script] adds numeric drop-reason codes to the
statistics.
Summary of changes (v5.3):
- The first pass (-p1) now runs parse operations concurrently over of
the hundreds of tapset .stp files, potentially saving seconds of
time at startup.
- Numerous kernel portability changes

Temporary workaround until jsc#PED-15105 is resolved.

Check that .../build/vmlinux.h actually exists before using it.
