Subject: [PATCH v8 2/6] powerpc/book3s64/radix: Add H_RPT_INVALIDATE pgsize encodings to mmu_psize_def
Date: Mon, 21 Jun 2021 14:19:59 +0530 [thread overview]
Message-ID: <20210621085003.904767-3-bharata@linux.ibm.com> (raw)
In-Reply-To: <20210621085003.904767-1-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.
