linux-stable.git/arch/arm64/boot, branch v4.0 Linux kernel stable tree arm64: juno: Fix misleading name of UART reference clock 2015-03-29T20:56:08+00:00 Dave Martin Dave.Martin@arm.com 2015-03-17T12:35:41+00:00 78d84bc3734c2566dbba09baae2414734661ed6a The UART reference clock speed is 7273.8 kHz, not 72738 kHz. Dots aren't usually used in node names even though ePAPR permits them. However, this can easily be avoided by expressing the frequency in Hz, not kHz. This patch changes the name to refclk7273800hz, reflecting the actual clock speed.

Since there's no architectural way of detecting the cpus that share particular cache, device tree can be used and the core cacheinfo already supports the same.
