Subject: [PATCH] arm64/cpuinfo: Drop boot_cpu_data
Date: Mon, 4 May 2020 18:00:00 +0530 [thread overview]
Message-ID: <1588595400-4560-1-git-send-email-anshuman.khandual@arm.com> (raw)
A global boot_cpu_data is not really required. Lets drop this. While
here, rename the local variable as boot_cpu_info when it is fetched
for the boot cpu.
