If the find(1) in scripts/gen_initramfs_list.sh generates any errors, it
will cause gen_initramfs_list.sh to fail (because of "set -e"), however
the errors from find are not printed to the user. This is rather confusing:
~/src/powerpc$ make O=~/build/powerpc-cell32/
make[2]: *** [usr/initramfs_data.cpio.gz] Error 1
make[1]: *** [usr] Error 2
make[1]: *** Waiting for unfinished jobs....
make[1]: *** wait: No child processes. Stop.
make: *** [_all] Error 2
It is much easier to work out what the problem is if we let the errors
from find hit the console, eg:
~/src/powerpc$ make O=~/build/powerpc-cell32/
find: /home/michael/initramfs-source/home: Permission denied
find: /home/michael/initramfs-source/lost+found: Permission denied

Make kbuild handle compressed cpio initramfs-es. An already compressed
cpio is copied directly to usr/, while a non-compressed cpio is filtered
through gzip (no changes here) on its way to usr/.
If the user has created a compressed cpio by other means, this saves him
from uncompressing it, just to be compressed again by kbuild.

I'm currently using CROSS_COMPILE="ccache arm-linux-". With that the bash
builtin command "type" searches for ccache and arm-linux-mkimage and so sets
MKIMAGE="/path/to/ccache" as I don't have arm-linux-mkimage. Then the script
dies with an error, that ccache doesn't support the argument -A.
This patch adds some quoting such that it works again for me.
Please note that this patch doesn't help you if you use ${CROSSCOMPILE}-mkimage
and ccache as mkuboot.sh now searches for the command
"ccache arm-linux-mkimage".

The following patch adds some extra clarification to the CONFIG_DEBUG_INFO
Kconfig help text. The current text is mostly a recursive definition and
doesn't really say much of anything. When I first read this I thought it
was going to enable extra verbosity in debug messages or something, but it
is only enabling the "gcc -g" compile option in the Makefile.

Most system calls seems to get added to i386 first. This patch
automatically generates a warning for any new system call which is
implemented on i386 but not the architecture currently being compiled.
On PowerPC at the moment, for example, it results in these warnings:
init/missing_syscalls.h:935:3: warning: #warning syscall sync_file_range not implemented
init/missing_syscalls.h:947:3: warning: #warning syscall getcpu not implemented
init/missing_syscalls.h:950:3: warning: #warning syscall epoll_pwait not implemented
The file scripts/checksyscalls.sh list a number of legacy system calls
that are ignored because they only makes sense on i386 systems.

up a patch in unified diff format *before* it is applied. Note that
the empty lines at the end of file detection *requires* that the diff was
taken with at least one line of context around each hunk, or bad things
will happen.
This script cleans up various classes of stealth whitespace. In
particular, it cleans up:
- Whitespace (spaces or tabs)before newline;
- DOS line endings (CR before LF);
- Space before tab (spaces are deleted or converted to tabs);
- Empty lines at end of file.

Only 1GB-aligned kernel/user splits are now handled for PAE. The
2GB/2GB split attempts to avoid aliasing vmallocspace with the 1:1
mapping for physical memory by using an actual split of 1.875/2.125
to accommodate 128MB of vmallocspace out of what would otherwise
be a full 2GB for userspace. That attempt disturbs the alignment
required by PAE for 2GB/2GB splits, and furthermore does not provide
a 2GB/2GB split as advertised.
This patch resolves the issues here in two manners. The first is
by providing a true 2GB/2GB split in addition to the 1.875/2.125
split. The second is by renaming the 1.875/2.125 split to
CONFIG_VMSPLIT_2G_OPT analogously to CONFIG_VMSPLIT_3G_OPT, which
performs a similar manuever to avoid aliasing vmallocspace with
the 1:1 mapping for physical memory around the 3GB boundary. With
the 1.875/2.125 split properly-named, its config option is then
tagged as depending on !HIGHMEM to express the PAE implementation's
current inability to deal with such unaligned splits.
This patch is essentially a combination of two patches, one written
