Set IORESOURCE_SYSTEM_RAM in flags of resource ranges with "System RAM", "Kernel code", "Kernel data", and "Kernel bss". Note that: - IORESOURCE_SYSRAM (i.e. modifier bit) is set in flags when IORESOURCE_MEM is already set. IORESOURCE_SYSTEM_RAM is defined as (IORESOURCE_MEM|IORESOURCE_SYSRAM). - Some archs do not set 'flags' for children nodes, such as "Kernel code". This patch does not change 'flags' in this case.

Change e820_reserve_resources() to set 'flags' and 'desc' from e820 types. Set E820_RESERVED_KERN and E820_RAM's (System RAM) io resource type to IORESOURCE_SYSTEM_RAM. Do the same for "Kernel data", "Kernel code", and "Kernel bss", which are child nodes of System RAM.

walk_iomem_res() and region_intersects() still need to use strcmp() for searching a resource entry by @name in the iomem table. This patch introduces I/O resource descriptor 'desc' in struct resource for the iomem search interfaces. Drivers can assign their unique descriptor to a range when they support the search interfaces. Otherwise, 'desc' is set to IORES_DESC_NONE (0). This avoids changing most of the drivers as they typically allocate resource entries statically, or by calling alloc_resource(), kzalloc(), or alloc_bootmem_low(), which set the field to zero by default. A later patch will address some drivers that use kmalloc() without zero'ing the field. Also change release_mem_region_adjustable() to set 'desc' when its resource entry gets separated. Other resource interfaces are also changed to initialize 'desc' explicitly although alloc_resource() sets it to 0.

I/O resource flags consist of I/O resource types and modifier bits. Therefore, checking an I/O resource type in 'flags' must be performed with a bitwise operation. Fix find_next_iomem_res() and region_intersects() that simply compare 'flags' against a given value. Also change __request_region() to set 'res->flags' from resource_type() and resource_ext_type() of the parent, so that children nodes will inherit the extended I/O resource type.

The IORESOURCE_MEM I/O resource type is used for all types of memory-mapped ranges, ex. System RAM, System ROM, Video RAM, Persistent Memory, PCI Bus, PCI MMCONFIG, ACPI Tables, IOAPIC, reserved, and so on. This requires walk_system_ram_range(), walk_system_ram_res(), and region_intersects() to use strcmp() against string "System RAM" to search for System RAM ranges in the iomem table, which is inefficient. __ioremap_caller() and reserve_memtype() on x86, for instance, call walk_system_ram_range() for every request to check if a given range is in System RAM ranges. However, adding a new I/O resource type for System RAM is not a viable option, see [1]. There are approx. 3800 references to IORESOURCE_MEM in the kernel/drivers, which makes it very difficult to distinguish their usages between new type and IORESOURCE_MEM. The I/O resource types are also used by the PNP subsystem. Therefore, introduce an extended I/O resource type, IORESOURCE_SYSTEM_RAM, which consists of IORESOURCE_MEM and a new modifier flag IORESOURCE_SYSRAM, see [2]. To keep the code 'if (resource_type(r) == IORESOURCE_MEM)' still working for System RAM, resource_ext_type() is added for extracting extended type bits.

This reverts commit 14e46e04. This ends up doing sysfs operations from deep in balance (where we should be GFP_NOFS) and under heavy balance load, we're making races against sysfs internals. Revert it for now while we figure things out. Signed-off-by: Chris Mason <clm@fb.com>

On Broxton, to make sure the reset controller works properly, MISCBDCGE bit (bit 6) in CGCTL (0x48) of PCI configuration space need be cleared before reset and set back to 1 after reset. Otherwise, it may prevent the CORB/RIRB logic from being reset. Signed-off-by: Libin Yang <libin.yang@linux.intel.com> Cc: <stable@vger.kernel.org> # v4.4+ Signed-off-by: Takashi Iwai <tiwai@suse.de>

Pull minor tracing fixes from Steven Rostedt: "This includes three minor fixes, mostly due to cut-and-paste issues. The first is a cut and paste issue that changed the amount of stack to skip when tracing a stack dump from 0 to 6, which basically made the stack disappear for small stack traces. The second fix is just removing an unused field in a struct that is no longer used, and currently just wastes space. The third is another cut-and-paste fix that had a tracepoint recording the wrong field (it was recording the previous field a second time)" * tag 'trace-v4.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing/dma-buf/fence: Fix timeline str value on fence_annotate_wait_on ftrace: Remove unused nr_trampolines var tracing: Fix stacktrace skip depth in trace_buffer_unlock_commit_regs()

These fixes works on my popmetal(rk3288) board. About patch: drm/atomic-helper: Export framebuffer_changed() Daniel Vetter ack for merging it through rockchip git trees, so framebuffer_changed() can be reused by drm/rockchip.

A bunch of etnaviv fixes for 4.5-rc. Most of them are fixing things in code paths that will only be hit if something goes wrong, which have been unearthed by more extensive testing. The only thing that doesn't really qualify as fixes is an UAPI extension that userspace wants to rely on being present, so I want to fast-track this into 4.5 before etnaviv ends up in a released kernel. * 'drm-etnaviv-fixes' of git://git.pengutronix.de/git/lst/linux: drm/etnaviv: call correct function when trying to vmap a DMABUF drm/etnaviv: rename etnaviv_gem_vaddr to etnaviv_gem_vmap drm/etnaviv: fix get pages error path in etnaviv_gem_vaddr drm/etnaviv: fix memory leak in IOMMU init path drm/etnaviv: add further minor features and varyings count drm/etnaviv: add helper for comparing model/revision IDs drm/etnaviv: add helper to extract bitfields drm/etnaviv: use defined constants for the chip model drm/etnaviv: update common and state_hi xml.h files drm/etnaviv: ignore VG GPUs with FE2.0 drm/etnaviv: fix failure path if model is zero drm/etnaviv: hold object lock while getting pages for coredump drm/etnaviv: remove owner assignment from platform_driver

This fixes a race condition in the error case: since the pt bos have not necessarily been reserved in case of an error, we could move a pt bo that is currently in the middle of being evicted/moved by another process, which then resulted in a BUG_ON in ttm_bo_add_to_lru.
