Linux-2.6.12-rc2 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!

MIPS: Move EARLY_PRINTK to Kconfig.debug Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT 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.

MIPS: Fix and enhance built-in kernel command line 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 <dmitri.vorobiev@movial.com> Cc: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/689/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

MIPS: Crazy spinlock speed test. 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_multi On my 600MHz octeon cn5860 (16 CPUs) I get spin_single spin_multi base 106885 247941 spinlock_patch 75194 219465 This shows that for uncontended locks the spinlock patch gives 41% improvement and for contended locks 12% improvement (1/time).
