Subject: [PATCH v1 3/3] x86/cpufeatures: Remove {disabled,required}-features.h
Date: Wed, 31 Jan 2024 21:46:29 -0800
Message-ID: <20240201054629.3816748-4-xin@zytor.com>
In-Reply-To: <20240201054629.3816748-1-xin@zytor.com>

The functionalities of {disabled,required}-features.h are replaced
with the auto-generated header cpufeature_masks.h. Thus they are no
longer needed. So delete them.

None of the macros defined in {disabled,required}-features.h is used
in tools directory, delete them.
