%description
This package contains the Linux kernel %kernel_base_version%kernel_sublevel \
with PREEMPT_RT patches (%kernel_extra_version) with some OSADL patches.

%package -n kernel-headers-%flavour
Summary: Header files for the Linux kernel
Group: Development/Kernel
Requires: kernel-headers-common
Provides: kernel-headers = %version
AutoReqProv: nocpp
#Provides: kernel-headers-%base_flavour = %version-%release

%description -n kernel-headers-%flavour
This package makes Linux kernel headers corresponding to the Linux
kernel package %name-%version-%release available for building
userspace programs (if this version of headers is selected by
adjust_kernel_headers).

Since Linux 2.6.18 the kernel build system supports creation of
sanitized kernel headers for use in userspace (by deleting headers
which are not usable in userspace and removing #ifdef __KERNEL__
blocks from installed headers).  This package contains sanitized
headers instead of raw kernel headers which were present in some
previous versions of similar packages.

If possible, try to use glibc-kernheaders instead of this package.

%package -n kernel-headers-modules-%flavour
Summary: Headers and other files needed for building kernel modules
Group: Development/Kernel 
Requires: gcc%kgcc_version
Requires: libelf-devel
AutoReqProv: nocpp

%description -n kernel-headers-modules-%flavour
This package contains header files, Makefiles and other parts of the
Linux kernel build system which are needed to build kernel modules for
the Linux kernel package %name-%version-%release.

If you need to compile a third-party kernel module for the Linux
kernel package %name-%version-%release, install this package
and specify %kbuild_dir as the kernel source
directory.

%package -n kernel-doc-%base_flavour
Summary: Linux kernel %kversion-%base_flavour documentation
Group: System/Kernel and hardware
BuildArch: noarch

%description -n kernel-doc-%base_flavour
This package contains documentation files for ALT Linux kernel packages:
 * kernel-image-%base_flavour-up-%kversion-%krelease
 * kernel-image-%base_flavour-smp-%kversion-%krelease

The documentation files contained in this package may be different
from the similar files in upstream kernel distributions, because some
patches applied to the corresponding kernel packages may change things
in the kernel and update the documentation to reflect these changes.
