.. and re-initialize th eanon_vma_chain head. This removes some boiler-plate from the users, and also makes it clear why it didn't need use the 'zalloc()' version. Signed-off-by:Linus Torvalds <torvalds@linux-foundation.org>

Linus Torvalds authored
The vm_area_struct is one of the most fundamental memory management objects, but the management of it is entirely open-coded evertwhere, ranging from allocation and freeing (using kmem_cache_[z]alloc and kmem_cache_free) to initializing all the fields. We want to unify this in order to end up having some unified initialization of the vmas, and the first step to this is to at least have basic allocation functions. Right now those functions are literally just wrappers around the kmem_cache_*() calls. This is a purely mechanical conversion: # new vma: kmem_cache_zalloc(vm_area_cachep, GFP_KERNEL) -> vm_area_alloc() # copy old vma kmem_cache_alloc(vm_area_cachep, GFP_KERNEL) -> vm_area_dup(old) # free vma kmem_cache_free(vm_area_cachep, vma) -> vm_area_free(vma) to the point where the old vma passed in to the vm_area_dup() function isn't even used yet (because I've left all the old manual initialization alone).

It was reported that a kernel crash happened in mem_cgroup_iter(), which can be triggered if the legacy cgroup-v1 non-hierarchical mode is used. Unable to handle kernel paging request at virtual address 6b6b6b6b6b6b8f ...... Call trace: mem_cgroup_iter+0x2e0/0x6d4 shrink_zone+0x8c/0x324 balance_pgdat+0x450/0x640 kswapd+0x130/0x4b8 kthread+0xe8/0xfc ret_from_fork+0x10/0x20 mem_cgroup_iter(): ...... if (css_tryget(css)) <-- crash here break; ...... The crashing reason is that mem_cgroup_iter() uses the memcg object whose pointer is stored in iter->position, which has been freed before and filled with POISON_FREE(0x6b). And the root cause of the use-after-free issue is that invalidate_reclaim_iterators() fails to reset the value of iter->position to NULL when the css of the memcg is released in non- hierarchical mode.

__split_huge_pmd_locked() must check if the cleared huge pmd was dirty, and propagate that to PageDirty: otherwise, data may be lost when a huge tmpfs page is modified then split then reclaimed. How has this taken so long to be noticed? Because there was no problem when the huge page is written by a write system call (shmem_write_end() calls set_page_dirty()), nor when the page is allocated for a write fault (fault_dirty_shared_page() calls set_page_dirty()); but when allocated for a read fault (which MAP_POPULATE simulates), no set_page_dirty().

Commit 26f09e9b ("mm/memblock: add memblock memory allocation apis") introduced two new function definitions: memblock_virt_alloc_try_nid_nopanic() memblock_virt_alloc_try_nid() and commit ea1f5f37 ("mm: define memblock_virt_alloc_try_nid_raw") introduced the following function definition: memblock_virt_alloc_try_nid_raw() This commit adds an include of header file <linux/bootmem.h> to provide the missing function prototypes. This silences the following gcc warning (W=1): mm/memblock.c:1334:15: warning: no previous prototype for `memblock_virt_alloc_try_nid_raw' [-Wmissing-prototypes] mm/memblock.c:1371:15: warning: no previous prototype for `memblock_virt_alloc_try_nid_nopanic' [-Wmissing-prototypes] mm/memblock.c:1407:15: warning: no previous prototype for `memblock_virt_alloc_try_nid' [-Wmissing-prototypes] Also adds #ifdef blockers to prevent compilation failure on mips/ia64 where CONFIG_NO_BOOTMEM=n as could be seen in commit commit 6cc22dc0 ("revert "mm/memblock: add missing include <linux/bootmem.h>""). Because Makefile already does: obj-$(CONFIG_HAVE_MEMBLOCK) += memblock.o The #ifdef has been simplified from: #if defined(CONFIG_HAVE_MEMBLOCK) && defined(CONFIG_NO_BOOTMEM) to simply: #if defined(CONFIG_NO_BOOTMEM) Link: http://lkml.kernel.org/r/20180626184422.24974-1-malat@debian.orgSigned-off-by:

Fix return code check for "max brightness" ACPI call. The Dell laptop ACPI video brightness control is not present on dell laptops anymore, but was present in older kernel versions. The code that checks the return value is incorrect since the SMM refactoring. The old code was: if (buffer->output[0] == 0) Which was changed to: ret = dell_send_request(...) if (ret) However, dell_send_request() will return 0 if buffer->output[0] == 0, so we must change the check to: if (ret == 0) This issue was found on a Dell M4800 laptop, and the fix tested on it as well.

This was causing problems on a system with a large amount of RAM, where display push buffers were being fetched incorrectly when placed in high system memory addresses. While this commit will resolve the issue on that particular system, the issue will be avoided completely with another patch to more fully solve problems with display and large amounts of system memory on Pascal. It's still probably a good idea to disable this to prevent weird issues in the future. Signed-off-by:Ben Skeggs <bskeggs@redhat.com>
