Setting '-e' flag tells shells to exit with error exit code immediately
after any of commands fails, and causes make(1) to regard recipes as
failed.
Before this, make will still continue to succeed even after the
installation failed, for example, for insufficient permission or
directory does not exist.

Many architectures have similar install.sh scripts.
The first half is really generic; it verifies that the kernel image
and System.map exist, then executes ~/bin/${INSTALLKERNEL} or
/sbin/${INSTALLKERNEL} if available.
The second half is kind of arch-specific; it copies the kernel image
and System.map to the destination, but the code is slightly different.
Factor out the generic part into scripts/install.sh.

Install targets (install, zinstall, uinstall) on arm have a dependency
to vmlinux. This may cause parts of the kernel to be rebuilt during
installation. We must avoid this since this may run as root. Install
targets "ABSOLUTELY MUST NOT MODIFY THE SOURCE TREE." as Linus
emphasized this in:
http://lkml.org/lkml/2013/7/10/600
So on arm and maybe other archs we need the same as for x86:
1648e4f8 x86, kbuild: make "make install" not depend on vmlinux
This patch fixes this for arm. Dependencies are removed and instead a
check to install.sh is added for the files that are needed.
This issue was uncovered by this build error where the -j option is
used in conjunction with install targets:
$ make <makeflags>
$ make <makeflags> zinstall
...
DEPMOD
Usage: .../scripts/depmod.sh /sbin/depmod <kernelrelease>
(INSTALL_MOD_PATH and INSTALL_PATH variables set, so no root perms
required in this case.)
The problem is that zinstall on arm due to its dependency to vmlinux
does a prepare/prepare3 and finally does a forced rewrite of
kernel.release even if it exists already.
Rebuilding kernel.release removes it first and then recreates it. This
might race with another parallel make job running depmod.
So this patch should fix this one too.
Also quoting $(KERNELRELEASE) arg for install.sh as this messes
argument order in case it is empty (which is the case if the kernel
was not built yet).

Replace the use of CROSS_COMPILE to select a customized
installkernel script with the possibility to set INSTALLKERNEL
to select a custom installkernel script when running make:
make INSTALLKERNEL=arm-installkernel install
With this patch we are now more consistent across
different architectures - they did not all support use
of CROSS_COMPILE.
The use of CROSS_COMPILE was a hack as this really belongs
to gcc/binutils and the installkernel script does not change
just because we change toolchain.
The use of CROSS_COMPILE caused troubles with an upcoming patch
that saves CROSS_COMPILE when a kernel is built - it would no
longer be installable.
[Thanks to Peter Z. for this hint]
This patch undos what Ian did in commit:
0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46
("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh")
The patch has been lightly tested on x86 only - but all changes
looks obvious.

The attached patch causes the various arch specific install.sh scripts to
look for ${CROSS_COMPILE}installkernel rather than just installkernel (in
both /sbin/ and ~/bin/ where the script already did this). This allows you
to have e.g. arm-linux-installkernel as a handy way to install on your
cross target. It also prevents the script picking up on the host
/sbin/installkernel which causes the script to fall through and do the
install itself (which is what I actually use myself, with $INSTALL_PATH
set).
I don't believe it causes back-compatibility problems since calling the
host installkernel was never likely to work or be what you wanted when
cross compiling anyway. If $CROSS_COMPILE isn't set then nothing changes.
I only use ARM and i386 myself but I figured it couldn't hurt to do the
whole lot. I've cc'd those who I hope are the arch maintainers for files
that I've touched.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
