From b5190516b282bee6f10569c3387d16f83447d280 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Tue, 18 Feb 2014 21:46:16 +0000 Subject: of: Move testcase FDT data into drivers/of The testcase data is usable by any platform. This patch moves it into the drivers/of directory so it can be included by any architecture. Using the test cases requires manually adding #include to the end of the boards .dtsi file and enabling CONFIG_OF_SELFTEST. Not pretty though. A useful project would be to make the testcase code easier to execute.

Weeks" Date: Mon, 3 Mar 2014 15:38:28 -0800 Subject: scripts/gen_initramfs_list.sh: fix flags for initramfs LZ4 compression LZ4 as implemented in the kernel differs from the default method now used by the reference implementation of LZ4. Until the in-kernel method is updated to support the new default, passing the legacy flag (-l) to the compressor is necessary. Without this flag the kernel-generated, LZ4-compressed initramfs is junk. Kyungsik said: : It seems that lz4 supports legacy format with the same option as lz4c : does. Just looking at the first few bytes of lz4 compressed image, we can : see whether it is new format or not. : : It shows new format magic number without this patch. New format magic : number is 0x184d2204. : : $ hexdump -C ./initramfs_data.cpio.lz4 |more : 00000000 04 22 4d 18 64 70 b9 69 (Little Endian) : ... : : Currently kernel supports legacy format only.

The problem was that the scripts/kallsyms.c file which generates the array of symbol names and addresses uses an relocatable value for all symbols, even absolute symbols. This patch fixes that.
