Subject: [RFC 5/9] elf: Remove _DL_HWCAP_PLATFORM
Date: Fri, 7 Jun 2024 13:42:40 +0200 [thread overview]
Message-ID: <20240607114543.659306-6-stli@linux.ibm.com> (raw)
In-Reply-To: <20240607114543.659306-1-stli@linux.ibm.com>
Remove the definitions of _DL_HWCAP_PLATFORM as those are not used
anymore after removal in elf/dl-cache.c:search_cache().
