It is based on patches from the linux-longsoon-community git tree: http://dev.lemote.com/cgit/linux-loongson-community.git/ Now the kernel can use the command line parameter from kexec-tools. Runtime tested on ar71xx with 2.6.39.4 (the wathdog must be stopped before executing the new kernel). Compile tested with lantiq (3.1.4) and brcm47xx (3.0.12). git-svn-id: svn://svn.openwrt.org/openwrt/trunk@29674 3c298f89-4303-0410-b956-a3cf2f4a3e73

Subject: MIPS: Fix compiling failure of relocate_kernel.S
|
|
|
|
The following errors is fixed with the help of <asm/asm_nosec.h>. for
|
|
this file need to put different symbols in the same section, the
|
|
original LEAF, NESTED and EXPORT (without explicit section indication)
|
|
must be used, <asm/asm_nosec.h> does it.
|
|
|
|
arch/mips/kernel/relocate_kernel.S: Assembler messages:
|
|
arch/mips/kernel/relocate_kernel.S:162: Error: operation combines symbols in different segments
