%package headers
Summary: Header files for the Linux kernel for use by glibc
Group: Development/System
# Obsoletes: kernel-headers
Provides: kernel-headers = %{version}
Requires: kernel-palladium-avx2 = %{version}
%description headers
Kernel-headers includes the C header files that specify the interface
between the Linux kernel and userspace libraries and programs.  The
header files define structures and constants that are needed for
building most standard programs and are also needed for rebuilding the
glibc package.

%package cross-headers
Summary: Header files for the Linux kernel for use by cross-glibc
Group: Development/System
# Obsoletes: kernel-cross-headers
Provides: kernel-cross-headers = %{version}
Requires: kernel-palladium-avx2 = %{version}

%description cross-headers
Kernel-cross-headers includes the C header files that specify the interface
between the Linux kernel and userspace libraries and programs.  The
header files define structures and constants that are needed for
building most standard programs and are also needed for rebuilding the
cross-glibc package.

Summary: Development package for building kernel modules to match the %{version} kernel

AutoReqProv: no
Requires: kernel-palladium-avx2 = %{version}
Provides: kernel-devel = %{version}
# Obsoletes: kernel-devel
%description devel
This package provides kernel headers and makefiles sufficient to build modules
against the %{version} kernel package.
