Alexander Shishkin c5d6c7708c ARM: 5841/1: a driver for on-chip ETM and ETB
This driver implements support for on-chip Embedded Tracing Macrocell and
Embedded Trace Buffer. It allows to trigger tracing of kernel execution flow
and exporting trace output to userspace via character device and a sysrq
combo.

Trace output can then be decoded by a fairly simple open source tool [1]
which is already sufficient to get the idea of what the kernel is doing.

Ben Dooks a18327f35a [ARM] S3C: Remove unused CONFIG_DEBUG_S3C_PORT
Remove the unused CONFIG_DEBUG_S3C_PORT as we currently only have
support for using the S3C UARTs via the low-level debug code.

Catalin Marinas adf8b37baf [ARM] 5386/2: unwind: Add Makefile and Kconfig entries for ARM stack unwinding
This patch also makes the frame pointer default to y only if
!ARM_UNWIND. LOCKDEP no longer selects FRAME_POINTER if ARM_UNWIND is
enabled.

Sascha Hauer ddf4e42c6a [ARM] CONFIG_DEBUG_STACK_USAGE
In early 2.6 days stack utilization instrumentation was made
configurable. Seems that arm misses the DEBUG_STACK_USAGE option.

Russell King eb8b0afc3a [ARM] Remove DEBUG_WAITQ
DEBUG_WAITQ appears to have been removed by others, but no one
removed the configuration option from ARM.  Remote it from both
Kconfig.debug and all default configurations.

Linus Torvalds 1da177e4c3 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!
