For most defconfigs, it was trivial to deduce the kernel version, by
just reading the version string, which could be:
- a standard upstream version string vX.Y.Z
- a non-standard version string, but still containg the standard X.Y.Z
Those for which it was not so trivial were those hosted on git tree.
Since most were already using a custom linux-headers version, it could
be easily deduced from that. It was confirmed by browsing said git trees
and check the version there.
There are a few cases were there was a mismatch:
- microzed: uses a 3.18 kernel, but 3.8 headers; fixed.
- xilinx_zc706: uses a 3.14 kernel, but 3.8 headers; fixed.
- zedboard: uses a 3.18 kernel, but 3.8 headers; fixed.

Fixes#8186
Mkfs.jffs2 accepts a --pagesize parameter, which allows specifying the size
of the virtual memory page size of the target machine, where the image will
be used. (This is the value of the PAGE_SIZE macro in Linux.) In most cases
the parameter doesn't need to be set as the default value of 4 kB is usually
correct.
The parameter was used incorrectly in Buildroot -- it was set to the page
size of flash memory chip -- this commit fixes this problem. Now the
--pagesize parameter is not used at all (unless the user explicitly chooses
to use a custom value during configuration). All existing defconfigs were
corrected to match the new configuration variable names.

Since commit 2a5cf5e (check kernel headers version), we also need to
specify the series of the custom kernel headers version.
The defconfigs file that define such a custom kernel headers version
now fail to build.
Add the required _AT_LEAST_X_Y options to those config files. Done with
this (convoluted but very fast, uch faster ythan manual editing!) rule:
for f in $( git grep -l BR2_DEFAULT_KERNEL_VERSION=\"3 ); do
grep -E '^BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_' "${f}" >/dev/null && continue
sed -r -e '/^(BR2_DEFAULT_KERNEL_VERSION="3\.([[:digit:]]+).*")$/s//\1\nBR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_3_\2=y/' "${f}"
done
Only kernels >= 3.0 need those options in the defconfig, since the
default for 2.6.x kernels is correct (selects _AT_LEAST_2_6), and
the default is not saved in a defconfig.

Notice that you need u-boot >= 2012.04 to be able to boot kernel >= 3.2,
because older u-boots keep the l2 cache enabled, see u-boot commit
679530278 (arm, arm-kirkwood: disable l2c before linux boot) for details.
