Subject: [GIT PULL v2 18/20] KVM: s390: move PGSTE softbits
Date: Fri, 31 Jan 2025 12:25:08 +0100 [thread overview]
Message-ID: <20250131112510.48531-19-imbrenda@linux.ibm.com> (raw)
In-Reply-To: <20250131112510.48531-1-imbrenda@linux.ibm.com>
Move the softbits in the PGSTEs to the other usable area.
This leaves the 16-bit block of usable bits free, which will be used in the
next patch for something else.
