Subject: [PATCH v3 0/6] Reduce memory usage for mm_context_t
Date: Wed, 17 Apr 2019 18:33:45 +0530 [thread overview]
Message-ID: <20190417130351.3805-1-aneesh.kumar@linux.ibm.com> (raw)
This patch moves hash translation related context variables to another structure
and runtime allocate that based on translation mode.
Aneesh Kumar K.V (6):
powerpc/mm/radix: Do slb preload only with hash translation mode
powerpc/mm: Remove PPC_MM_SLICES #ifdef for book3s64
powerpc/mm: Add helpers for accessing hash translation related
variables
powerpc/mm: Move slb_addr_linit to early_init_mmu
powerpc/mm: Reduce memory usage for mm_context_t for radix
powerc/mm/hash: Reduce hash_mm_context size
