Subject: [PATCH v10 03/39] arm64: cpufeature: Always specify and use a field width for capabilities
Date: Wed, 26 Jan 2022 15:27:13 +0000	[thread overview]
Message-ID: <20220126152749.233712-4-broonie@kernel.org> (raw)
In-Reply-To: <20220126152749.233712-1-broonie@kernel.org>

Since all the fields in the main ID registers are 4 bits wide we have up
until now not bothered specifying the width in the code. Since we now
wish to use this mechanism to enumerate features from the floating point
feature registers which do not follow this pattern add a width to the
table.  This means updating all the existing table entries but makes it
less likely that we run into issues in future due to implicitly assuming
a 4 bit width.
