Subject: [PATCH v5 5/8] KVM: x86: Use kcalloc to allocate the mce_banks array.
Date: Fri, 10 Jun 2022 10:11:31 -0700 [thread overview]
Message-ID: <20220610171134.772566-6-juew@google.com> (raw)
In-Reply-To: <20220610171134.772566-1-juew@google.com>
This patch updates the allocation of mce_banks with the array allocation
API (kcalloc) as a precedent for the later mci_ctl2_banks to implement
per-bank control of Corrected Machine Check Interrupt (CMCI).
