Subject: [Xen-devel] [PATCH v5 0/2] x86: scratch cpumask fixes/improvement
Date: Fri, 28 Feb 2020 13:07:51 +0100	[thread overview]
Message-ID: <20200228120753.38036-1-roger.pau@citrix.com> (raw)

Hello,

Following series contain yet one more bugfix that removes the usage of
the scratch cpumask in send_IPI_mask and the introduction of accessors
to get/put the per-CPU scratch cpumask in order to prevent such issues
form happening in the future.

Thanks, Roger.
