In linux-next we now see AMDGPU and # nouveau to be using this API. # # - Remove old or transitional hmm APIs. These are hold overs from the # past with no users, or APIs that existed only to manage cross tree # conflicts. There are still a few more of these cleanups that didn't # make the merge window cut off. # # - Improve some core mm APIs: # - export alloc_pages_vma() for driver use # - refactor into devm_request_free_mem_region() to manage # DEVICE_PRIVATE resource reservations # - refactor duplicative driver code into the core dev_pagemap # struct # # - Remove hmm wrappers of improved core mm APIs, instead have drivers # use the simplified API directly # # - Remove DEVICE_PUBLIC # # - Simplify the kconfig flow for the hmm users and core code" # # * tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (42 commits) # mm: don't select MIGRATE_VMA_HELPER from HMM_MIRROR # mm: remove the HMM config option # mm: sort out the DEVICE_PRIVATE Kconfig mess # mm: simplify ZONE_DEVICE page private data # mm: remove hmm_devmem_add # mm: remove hmm_vma_alloc_locked_page # nouveau: use devm_memremap_pages directly # nouveau: use alloc_page_vma directly # PCI/P2PDMA: use the dev_pagemap internal refcount # device-dax: use the dev_pagemap internal refcount # memremap: provide an optional internal refcount in struct dev_pagemap # memremap: replace the altmap_valid field with a PGMAP_ALTMAP_VALID flag # memremap: remove the data field in struct dev_pagemap # memremap: add a migrate_to_ram method to struct dev_pagemap_ops # memremap: lift the devmap_enable manipulation into devm_memremap_pages # memremap: pass a struct dev_pagemap to ->kill and ->cleanup # memremap: move dev_pagemap callbacks into a separate structure # memremap: validate the pagemap type passed to devm_memremap_pages # mm: factor out a devm_request_free_mem_region helper # mm: export alloc_pages_vma # ... # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 fec88ab0af9706b2201e5daf377c5031c62d11f7 # < make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:38: LSE atomics not supported by binutils arch/arm64/Makefile:56: CROSS_COMPILE_COMPAT not defined or empty, the compat vDSO will not be built /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c: In function 'sh_mobile_i2c_isr': /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:399:26: warning: 'data' may be used uninitialized in this function [-Wmaybe-uninitialized] pd->msg->buf[real_pos] = data; ^ /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:372:16: note: 'data' was declared here unsigned char data; ^ In file included from /kisskb/src/include/linux/rwsem.h:16:0, from /kisskb/src/include/linux/notifier.h:15, from /kisskb/src/include/linux/clk.h:14, from /kisskb/src/drivers/tty/serial/sh-sci.c:24: /kisskb/src/drivers/tty/serial/sh-sci.c: In function 'sci_dma_rx_submit': /kisskb/src/include/linux/spinlock.h:288:3: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized] _raw_spin_unlock_irqrestore(lock, flags); \ ^ /kisskb/src/drivers/tty/serial/sh-sci.c:1353:16: note: 'flags' was declared here unsigned long flags; ^ Completed OK # rm -rf /kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 # Build took: 0:02:30.789569
