Subject: [PATCH v7 2/6] powerpc/book3s64/radix: Add H_RPT_INVALIDATE pgsize encodings to mmu_psize_def
Date: Wed, 05 May 2021 15:58:38 +0000	[thread overview]
Message-ID: <20210505154642.178702-3-bharata@linux.ibm.com> (raw)
In-Reply-To: <20210505154642.178702-1-bharata@linux.ibm.com>

Add a field to mmu_psize_def to store the page size encodings
of H_RPT_INVALIDATE hcall. Initialize this while scanning the radix
AP encodings. This will be used when invalidating with required
page size encoding in the hcall.
