This is on a beagleboard c4.

Trying to make the new kernel config, there are new parameters that I don’t know the correct answers to.

I got http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.2.tar.bz2 extracted it, got my current config from zcat /proc/config.gz >>.config then

sandisk4gb:~/src$ cd linux-3.2
sandisk4gb:~/src/linux-3.2$ make oldconfig
HOSTCC scripts/basic/fixdep
HOSTCC scripts/kconfig/conf.o
SHIPPED scripts/kconfig/zconf.tab.c
SHIPPED scripts/kconfig/zconf.lex.c
SHIPPED scripts/kconfig/zconf.hash.c
HOSTCC scripts/kconfig/zconf.tab.o
HOSTLD scripts/kconfig/conf
scripts/kconfig/conf --oldconfig Kconfig

Patch physical to virtual translations at runtime (ARM_PATCH_PHYS_VIRT)

Or you enable (Y) ^ and then not worry about PHYS_OFFSET..

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob;f=arch/arm/Kconfig#l198

Physical address of main memory (PHYS_OFFSET) [] (NEW)

For reference, this v3.2 config:
https://github.com/RobertCNelson/stable-kernel/blob/master/patches/defconfig

boots fine on a beagle c4, xm, igepv2, panda... Lots of extra things
enabled, but it'll give you an idea..

Thanks. I had to do a make menuconfig instead of make oldconfig to be able to flip the option ARM_PATCH_PHYS_VIRT to “y”.

My device is running a very customized and limited kernel and I wanted to see how it worked with the latest release.
