Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it
to lib/Kconfig.debug so each arch doesn't have to define it. This
obviously makes the option generic, but that's fine because the config is
already used in generic code.It's not obvious to me that sysrq-P actually does anything caution by
keeping the most inclusive wording.Signed-off-by: Stephen Boyd

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.Reviewed-by: Ingo Molnar

This is just a test program for raw_spinlocks. The main reason I
wrote it is to validate my spinlock changes that I sent in a previous
patch.To use it enable CONFIG_DEBUG_FS and CONFIG_SPINLOCK_TEST then at run
time do:# mount -t debugfs none /sys/kernel/debug/
# cat /sys/kernel/debug/mips/spin_single
# cat /sys/kernel/debug/mips/spin_multiOn my 600MHz octeon cn5860 (16 CPUs) I get
spin_single spin_multi
base 106885 247941
spinlock_patch 75194 219465This shows that for uncontended locks the spinlock patch gives 41%
improvement and for contended locks 12% improvement (1/time).Signed-off-by: David Daney

This patch adds a new DEBUG_ZBOOT option to allow the users to enable it
to debug the compressed kernel support for a new board and this optoin
should be disabled to reduce the kernel image size and speed up the
kernel booting procedure when the compressed kernel support is stable.Signed-off-by: Wu Zhangjin

Currently, MIPS kernels silently overwrite kernel command-line parameters
hardcoded in CONFIG_CMDLINE by the ones received from firmware. Therefore,
using firmware remains the only reliable method to transfer the
command-line parameters, which is not always desirable or convenient, and
the CONFIG_CMDLINE option is thereby effectively rendered useless.This patch fixes the problem described above and introduces a more flexible
scheme of handling the kernel command line, in a manner identical to what is
currently used for x86. The default behavior, i.e. when CONFIG_CMDLINE_BOOL
is not defined, retains the existing semantics, and firmware command-line
arguments override the hardcoded ones.[Ralf: I fixed up all the defconfig files so the stay unaffected by this
change.]Signed-off-by: Dmitri Vorobiev

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
