Subject: ARM: hwcaps: use shifts instead of hardcoded constants
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=194a7f720f6f009867a01b760f311b68f1e81872;p=linux-beck.git

ARM: hwcaps: use shifts instead of hardcoded constants

The HWCAP numbers are defined as constants, each one being a power of 2.
This has become slightly unwieldy now that we have reached 32k.

This patch changes the HWCAP defines to use (1 << n) instead of coding
the constant directly. The values remain unchanged.
