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!

ARM: implement CONFIG_STRICT_DEVMEM by disabling access to RAM via /dev/mem There are very few legitimate use cases, if any, for directly accessing system RAM through /dev/mem.

bool "Filter access to /dev/mem"

---help---
If this option is disabled, you allow userspace (root) access to all
of memory, including kernel and userspace memory. Accidental
access to this is obviously disastrous, but specific access can
be used by people debugging the kernel.
If this option is switched on, the /dev/mem file only allows
userspace access to memory mapped peripherals.
If in doubt, say Y.

config DEBUG_USER
bool "Verbose user fault messages"
help
When a user program crashes due to an exception, the kernel can
print a brief message explaining what the problem was. This is
sometimes helpful for debugging but serves no purpose on a
production system. Most people should say N here.
In addition, you need to pass user_debug=N on the kernel command
line to enable this feature. N consists of the sum of:
1 - undefined instruction events
2 - system calls
4 - invalid data aborts
8 - SIGSEGV faults
16 - SIGBUS faults

ARM: initial multiplatform support This lets us build a multiplatform kernel for experimental purposes. However, it will not be useful for any real work, because it relies on a number of useful things to be disabled for now: * SMP support must be turned off because of conflicting symbols. Marc Zyngier has proposed a solution by adding a new SOC operations structure to hold indirect function pointers for these, but that work is currently stalled * We turn on SPARSE_IRQ unconditionally, which is not supported on most platforms. Each of them is currently in a different state, but most are being worked on. * A common clock framework is in place since v3.4 but not yet being used. Work on this is on its way. * DEBUG_LL for early debugging is currently disabled. * THUMB2_KERNEL does not work with allyesconfig because the kernel gets too big [Rob Herring]: Rebased to not be dependent on the mass mach header rename.

ARM: 7072/1: debug: use kconfig choice for selecting DEBUG_LL UART Enabling CONFIG_DEBUG_LL (which is required for earlyprintk) hardwires the debug UART address into the kernel, so that we can print before the platform is initialised. If the user inadvertently selects multiple platforms with DEBUG_LL enabled, the UART address may not be correct and will likely cause the kernel to hang in the very early stages of boot. This patch, based on a skeleton from Russell, uses a Kconfig choice for selecting the DEBUG_LL UART, therefore allowing the user to make a choice about the supported platform when DEBUG_LL is enabled.

ARM: Add an earlyprintk debug console This patch allows an earlyprintk console if CONFIG_DEBUG_LL is enabled, using the printch asm function. The patch is based on the original work by Sascha Hauer.

Say Y here if you want to have an early console using the
kernel low-level debugging functions. Add earlyprintk to your
kernel parameters to enable this console.
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.

config OC_ETM
bool "On-chip ETM and ETB"
ARM: OC_ETM should not select ARM_AMBA The CONFIG_ARM_AMBA symbol is selected by the platforms that support AMBA, and the other platforms (e.g. orion) might not be able to build that code at all when they do not support the clk API. Instead, make sure that OC_ETM is only built on platforms that do support the amba subsystem already. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

ARM: 7445/1: mm: update CONTEXTIDR register to contain PID of current process This patch introduces a new Kconfig option which, when enabled, causes the kernel to write the PID of the current task into the PROCID field of the CONTEXTIDR on context switch. This is useful when analysing hardware trace, since writes to this register can be configured to emit an event into the trace stream. The thread notifier for writing the PID is deliberately kept separate from the ASID-writing code so that we can support newer processors using LPAE, where the ASID is stored in TTBR0. As such, the switch_mm code is updated to perform a read-modify-write sequence to ensure that we don't clobber the PID on CPUs using the classic 2-level page tables.

bool "Write the current PID to the CONTEXTIDR register"
depends on CPU_COPY_V6
help
Enabling this option causes the kernel to write the current PID to
the PROCID field of the CONTEXTIDR register, at the expense of some
additional instructions during context switch. Say Y here only if you
are planning to use hardware trace tools with this kernel.
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!
