Fix the start/end address calculation for address ranges that span multiple page directories in amdgpu_vm_alloc_levels. Add error messages if page tables aren't found. Otherwise the page table update would just fail silently. v2: * Change WARN_ON to WARN_ON_ONCE * Move masking of high address bits to caller * Add range-check for "from" and "to" v3: * Replace WARN_ON_ONCE in get_pt with pr_err in caller Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
