Subject: [PATCH v1 12/13] KVM: s390: move PGSTE softbits
Date: Wed, 8 Jan 2025 19:14:50 +0100 [thread overview]
Message-ID: <20250108181451.74383-13-imbrenda@linux.ibm.com> (raw)
In-Reply-To: <20250108181451.74383-1-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.
