*	ARM: 6026/1: ARM: Add support for LZMA-compressed kernel images	Albin Tonnerre	2010-04-14	1	-0/+4
\| \| \| \| \| \| \| \| \| \| \| \|	This patch allows using a kernel image compressed with LZMA on ARM. Extracting the image is fairly slow, but it might be useful on machines with a very limited amount of storage, as the size benefit is quite significant (about 25% smaller with LZMA compared to GZIP) Tested-by: Martin Michlmayr <tbm@cyrius.com> Tested-by: Paulius Zaleckas <paulius.zaleckas@gmail.com> Signed-off-by: Albin Tonnerre <albin.tonnerre@free-electrons.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
*	ARM: Add final piece to fix XIP decompressor in read-only memory	Russell King	2010-03-15	1	-0/+1
\| \| \| \| \| \| \|	This defines STATIC_RW_DATA, which prevents the read/write malloc management data being declared with a static attribute. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
*	ARM: Eliminate decompressor -Dstatic= PIC hack	Russell King	2010-02-25	1	-0/+45
	We used to build decompressors with -Dstatic= to avoid any local data being generated. The problem is that local data generates GOTOFF relocations, which means we can't relocate the data relative to the text segment. Global data, on the other hand, goes through the GOT, and can be relocated anywhere. Unfortunately, with the new decompressors, this presents a problem since they declare static data within functions, and this leads to stack overflow. Fix this by separating out the decompressor code into a separate file, and removing 'static' from BSS data in misc.c. Also, discard the .data section - this means that should we end up with read/write initialized data, the decompressor will fail to link and the problem will be obvious.
