2011-02-23x86: Add device tree supportSebastian Andrzej Siewior
This patch adds minimal support for device tree on x86. The device tree blob is passed to the kernel via setup_data which requires at least boot protocol 2.09. Memory size, restricted memory regions, boot arguments are gathered the traditional way so things like cmd_line are just here to let the code compile. The current plan is use the device tree as an extension and to gather information which can not be enumerated and would have to be hardcoded otherwise. This includes things like - which devices are on this I2C/SPI bus? - how are the interrupts wired to IO APIC? - where could my hpet be?

2011-02-16hwmon: (jc42) do not allow writing to locked registersClemens Ladisch
On systems where the temperature sensor is actually used, the BIOS is likely to have locked the alarm registers. In that case, all writes through the corresponding sysfs files would be silently ignored. To prevent this, detect the locks and make the affected sysfs files read-only.

2011-02-07tracing/syscalls: Allow arch specific syscall symbol matchingIan Munsie
Some architectures have unusual symbol names and the generic code to match the symbol name with the function name for the syscall metadata will fail. For example, symbols on PPC64 start with a period and the generic code will fail to match them. This patch moves the match logic out into a separate function which an arch can override by defining ARCH_HAS_SYSCALL_MATCH_SYM_NAME in asm/ftrace.h and implementing arch_syscall_match_sym_name.

Add bitfield type for tracing arguments on kprobe-tracer.
