%description
This is a custom build of the Linux kernel from the 'ath' git tree, specifically
the 'ath-next' branch, intended for testing wireless drivers.

%prep

#The Source0 tarball is named 'ath.git-ath-next.tar.gz' and unpacks to a directory
#with a similar name. Using '%setup -q' without the '-n' flag is more robust
#as it handles the directory name automatically.
%setup -q
cp %{SOURCE1} .config

%build

Use a standard build process for the kernel.
make %{?_smp_mflags}
make olddefconfig
make %{?_smp_mflags}

%install

Install the kernel and modules into the build root.
make INSTALL_MOD_PATH=%{buildroot} modules_install
make INSTALL_HDR_PATH=%{buildroot}/usr headers_install
make INSTALL_PATH=%{buildroot}/boot install

The following lines are used to clean up the build.
%clean
rm -rf %{buildroot}
