litmus-rt.git/arch/powerpc/configs/adder875_defconfig, branch master The LITMUS^RT kernel. powerpc: Update all configs using savedefconfig 2015-01-20T07:06:58+00:00 Michael Ellerman mpe@ellerman.id.au 2015-01-20T06:36:53+00:00 a85cade6762bf566698e625ec1a4461245e40768 It looks like it's ~4 years since we updated some of these, so do a bulk update. Verified that the before and after generated configs are exactly the same. Which begs the question why update them? The answer is that it can be confusing when the stored defconfig drifts too far from the generated result. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> 
It looks like it's ~4 years since we updated some of these, so do a bulk
update.

Verified that the before and after generated configs are exactly the
same.

Which begs the question why update them? The answer is that it can be
confusing when the stored defconfig drifts too far from the generated
result.

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT 2011-01-21T01:02:05+00:00 David Rientjes rientjes@google.com 2011-01-20T22:44:16+00:00 6a108a14fa356ef607be308b68337939e56ea94e The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.
