Conflicts are expected in two files - asm/timex.h and mach-integrator/integrator_cp.c. Nothing particularly stands out more than anything else. Most of the growth is down to the opcodes stuff from Dave Martin, which is countered by Rob's patches to use more of the asm-generic headers on ARM."

The bootloader should be masking these anyway, but this reduces the damage window just in case it doesn't. * Enter svc mode via exception return to ensure that CPU state is properly serialised. This does not matter when switching from an ordinary privileged mode ("PL1" modes in ARMv7-AR rev C parlance), but it potentially does matter when switching from a another privileged mode such as hyp mode. This should allow the kernel to boot safely either from svc mode or hyp mode, even if no support for use of the ARM Virtualization Extensions is built into the kernel.

It has to explicitly be disabled, and only when DT support is selected. Note: disabling kernel ATAGS support does not prevent the usage of CONFIG_ARM_ATAG_DTB_COMPAT.

Also rename compat.c to atags_compat.c to make it clearer what it is about. Same for atags.c which is now atags_proc.c. Gather all the atags function declarations into a common atags.h.

Since then, OProfile for ARM has moved to using perf as its backend, so the reservation code is no longer used. This patch removes the reservation code for the CPU PMU on ARM.
