+Subject: [PATCH] configure: Avoid use of AC_CHECK_FILE for cross compiling
+
+The AC_CHECK_FILE macro can't be used for cross compiling as it will
+result in "error: cannot check for file existence when cross compiling".
+Replace it with the AS_IF macro.

+Subject: [PATCH] llvmpipe: remove the power of two sizeof(struct cmd_block)
+ assertion
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It fails on 32-bit systems (I only tested on 64-bit).  Power of two
+size isn't required, so just remove the assertion.
