+Subject: ARM: 8012/1: kdump: Avoid overflow when converting pfn to physaddr
+
+From: Liu Hua <sdu.liu@huawei.com>
+
+commit 8fad87bca7ac9737e413ba5f1656f1114a8c314d upstream.
+
+When we configure CONFIG_ARM_LPAE=y, pfn << PAGE_SHIFT will
+overflow if pfn >= 0x100000 in copy_oldmem_page.
+So use __pfn_to_phys for converting.

+Subject: posix_acl: handle NULL ACL in posix_acl_equiv_mode
+
+From: Christoph Hellwig <hch@lst.de>
+
+commit 50c6e282bdf5e8dabf8d7cf7b162545a55645fd9 upstream.
+
+Various filesystems don't bother checking for a NULL ACL in
+posix_acl_equiv_mode, and thus can dereference a NULL pointer when it
+gets passed one. This usually happens from the NFS server, as the ACL tools
+never pass a NULL ACL, but instead of one representing the mode bits.
+
+Instead of adding boilerplat to all filesystems put this check into one place,
+which will allow us to remove the check from other filesystems as well later
+on.
