From 2a9e3882906f722af2ff1375a776fa1980abac26 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Sat, 6 Jul 2019 02:02:01 -0400 Subject: kernel/vm_manager: Rename 'new map' to 'stack' Provides a more accurate name for the memory region and also disambiguates between the map and new map regions of memory, making it easier to understand. --- src/core/hle/kernel/svc.cpp | 20 ++++++++++---------- src/core/hle/kernel/vm_manager.cpp | 34 +++++++++++++++++----------------- src/core/hle/kernel/vm_manager.h | 20 ++++++++++---------- 3 files changed, 37 insertions(+), 37 deletions(-) (limited to 'src/core/hle/kernel') diff --git a/src/core/hle/kernel/svc.cpp b/src/core/hle/kernel/svc.cpp index de6363ff2..332573a95 100644 --- a/src/core/hle/kernel/svc.cpp +++ b/src/core/hle/kernel/svc.cpp @@ -98,9 +98,9 @@ ResultCode MapUnmapMemorySanityChecks(const VMManager& vm_manager, VAddr dst_add return ERR_INVALID_ADDRESS_STATE;
