| 2010-12-20 | ARM: SMP: remove smp_mpidr.h | Russell King | |
| With "ARM: CPU hotplug: remove bug checks in platform_cpu_die()", we now do not use hard_smp_processor_id(), we no longer need to read the hardware processor ID. Remove the include providing this function. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> | |||
| 2010-10-04 | ARM: Allow SMP kernels to boot on UP systems | Russell King | |
| UP systems do not implement all the instructions that SMP systems have, so in order to boot a SMP kernel on a UP system, we need to rewrite parts of the kernel. Do this using an 'alternatives' scheme, where the kernel code and data is modified prior to initialization to replace the SMP instructions, thereby rendering the problematical code ineffectual. We use the linker to generate a list of 32-bit word locations and their replacement values, and run through these replacements when we detect a UP system.
