*	arm64: kernel: compiling issue, need delete read_current_timer()	Chen Gang	2013-06-10	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Under arm64, we will calibrate the delay loop statically using a known timer frequency, so delete read_current_timer(), or it will cause compiling issue with allmodconfig. The related error: ERROR: "read_current_timer" [lib/rbtree_test.ko] undefined! ERROR: "read_current_timer" [lib/interval_tree_test.ko] undefined! ERROR: "read_current_timer" [fs/ext4/ext4.ko] undefined! ERROR: "read_current_timer" [crypto/tcrypt.ko] undefined!

*	arm64: Generic timers support	Marc Zyngier	2012-09-17	1	-0/+29
	This patch adds support for the ARM generic timers with A64 instructions for accessing the timer registers. It uses the physical counter as the clock source and the virtual counter as sched_clock. The timer frequency can be specified via DT or read from the CNTFRQ_EL0 register. The physical counter is also accessible from user space allowing fast gettimeofday() implementation.
