[PATCH] platforms/powernv: Fix update of NVLink DMA mask

The emulated NVLink PCI devices share the same IODA2 TCE tables but only support a single TVT (instead of the normal two for PCI devices). This requires the kernel to manually replace windows with either the bypass or non-bypass window depending on what the driver has requested. Unfortunately an

[PATCH] misc: cxl: fix build for GCC 4.6.x

GCC 4.6.3 does not support -Wno-unused-const-variable. Instead, use the kbuild infrastructure that checks if this options exists. Also drop -Werror, since it's harmful, if forced on the user. New GCC's, or higher warning verbosities (e.g., W=1) can easily kill the build where they shouldn't.

Hi, I'm using a GCC 4.6.3 compiler for some compile tests, and I noticed that commit 2cd55c68c0a4 ("cxl: Fix build failure due to -Wunused-variable behaviour change") breaks my builds, because the -Wno-unused-const-variable doesn't exist on GCC 4.6.3. drivers/misc/cxl/base.c: At top level:
