Commit ffe8018c3424 ("initramfs: fix initramfs size calculation") broke
32-bit big-endian arches like (on ARAnyM):VFS: Cannot open root device "hda1" or unknown-block(3,1)

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1)As pointed out by Kerstin Jonsson , this
is due to CONFIG_32BIT not being defined, so the initramfs size field is
done as a 64-bit quad. On little-endian (like x86) this doesn matter,
but on a big-endian machine the 32-bit reads will see the (zero) high
bits.Only mips, s390, and score set CONFIG_32BIT for 32-bit builds, so fix it for
all other 32-bit arches by inverting the logic and testing for CONFIG_64BIT,
which should be defined on all 64-bit arches.Signed-off-by: Geert Uytterhoeven

The size of a built-in initramfs is calculated in init/initramfs.c by
"__initramfs_end - __initramfs_start". Those symbols are defined in the
linker script include/asm-generic/vmlinux.lds.h:#define INIT_RAM_FS \
. = ALIGN(PAGE_SIZE); \
VMLINUX_SYMBOL(__initramfs_start) = .; \
*(.init.ramfs) \
VMLINUX_SYMBOL(__initramfs_end) = .;If the initramfs file has an odd number of bytes, the "__initramfs_end"
symbol points to an odd address, for example, the symbols in the
System.map might look like:0000000000572000 T __initramfs_start
00000000005bcd05 T __initramfs_end :
540a9c: eb cf f0 78 00 24 stmg %r12,%r15,120(%r15),
540aa2: c0 10 00 01 8a af larl %r1,572000
540aa8: c0 c0 00 03 e1 2e larl %r12,5bcd04
(Instead of 5bcd05)
...
540abe: 1b c1 sr %r12,%r1To fix the problem, this patch introduces the global variable
__initramfs_size, which is calculated in the "usr/initramfs_data.S" file.
The populate_rootfs() function can then use the start marker of the
.init.ramfs section and the value of __initramfs_size for loading the
initramfs. Because the start marker and size is sufficient, the
__initramfs_end symbol is no longer needed and is removed.Signed-off-by: Michael Holzheu

Remove initramfs_data.{lzo,lzma,gz,bz2}.S variants and use a common
implementation in initramfs_data.S. The common implementation expects the
file name of the initramfs to be defined in INITRAMFS_IMAGE.Change the Makefile to set the INITRAMFS_IMAGE define symbol according
to the selected compression method.Signed-off-by: Hendrik Brueckner

Impact: Resolves build failures in some configurations
Makes it possible to disable CONFIG_RD_GZIP . In that case, the
built-in initramfs will be compressed by whatever compressor is
available (bzip2 or lzma) or left uncompressed if none is available.It also removes a couple of warnings which occur when no ramdisk
compression at all is chosen.It also restores the select ZLIB_INFLATE in drivers/block/Kconfig
which somehow came missing. This is needed to activate compilation of
the stuff in zlib_deflate.Signed-off-by: Alain Knaff

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!
