ARM64: /proc/interrupts: display IPIs of online CPUs only (2013-11-07 17:26:54 +0000)
----------------------------------------------------------------
Main features:
- Ticket-based spinlock implementation and lockless lockref support
- Big endian support
- CPU hotplug support, currently for PSCI (Power State Coordination
Interface) capable firmware
- Virtual address space extended to 42-bit in the 64K page configuration
(maximum VA space with 2 levels of page tables)
- Compat (AArch32) kuser helpers updated to ARMv8 (make use of
load-acquire/store-release instructions)
- Code cleanup, defconfig update and minor fixes
