%package doc
Summary: Various documentation bits found in the kernel source
Group: Documentation
%description doc
This package contains documentation files from the kernel
source. Various bits of information about the Linux kernel and the
device drivers shipped with it are documented in these files.

You'll want to install this package if you need a reference to the
options that can be passed to Linux kernel modules at load time.

%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
%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.

This package is required by %{name}-debuginfo subpackages.
It provides the kernel source files common to all builds.

This package contains the perf tool, which enables performance monitoring
of the Linux kernel.

This package provides debug information for the perf package.

# Note that this pattern only works right to match the .build-id
# symlinks because of the trailing nonmatching alternation and

# Since they are userspace binaries, they are required to pickup the hardening
# flags defined in the macros. The --build-id=uuid is a trick to get around
# debuginfo limitations: Typically, find-debuginfo.sh will update the build
# id of all binaries to allow for parllel debuginfo installs. The kernel
# can't use this because it breaks debuginfo for the vDSO so we have to
# use a special mechanism for kernel and modules to be unique. Unfortunately,
# we still have userspace binaries which need unique debuginfo and because
# they come from the kernel package, we can't just use find-debuginfo.sh to
# rewrite only those binaries. The easiest option right now is just to have
# the build id be a uuid for the host programs.
#
# Note we need to disable these flags for cross builds because the flags
# from redhat-rpm-config assume that host == target so target arch
# flags cause issues with the host compiler.
