Descriptions

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix shift-out-of-bounds in CalculateVMAndRowBytes [WHY]
When PTEBufferSizeInRequests is zero, UBSAN reports the following
warning because dml_log2 returns an unexpected negative value: shift exponent 4294966273 is too large for 32-bit type 'int' [HOW] In the case PTEBufferSizeInRequests is zero, skip the dml_log2() and
assign the result directly.
