+Subject: do_generic_file_read: clear page errors when issuing a fresh read of the page
+
+From: Jeff Moyer <jmoyer@redhat.com>
+
+commit 91803b499cca2fe558abad709ce83dc896b80950 upstream.
+
+I/O errors can happen due to temporary failures, like multipath
+errors or losing network contact with the iSCSI server. Because
+of that, the VM will retry readpage on the page.
+
+However, do_generic_file_read does not clear PG_error.  This
+causes the system to be unable to actually use the data in the
+page cache page, even if the subsequent readpage completes
+successfully!
+
+The function filemap_fault has had a ClearPageError before
+readpage forever.  This patch simply adds the same to
+do_generic_file_read.

+Subject: gconfig: fix build failure on fedora 13
+
+From: Richard Kennedy <richard@rsk.demon.co.uk>
+
+commit cbab05f041a4cff6ca15856bdd35238b282b64eb upstream.
+
+Making gconfig fails on fedora 13 as the linker cannot resolve dlsym.
+
+Adding libdl to the link command fixes this.
+
+make shows this error :-
+    /usr/bin/ld: scripts/kconfig/kconfig_load.o: undefined reference to symbol 'dlsym@@GLIBC_2.2.5'
+    /usr/bin/ld: note: 'dlsym@@GLIBC_2.2.5' is defined in DSO /lib64/libdl.so.2 so try adding it to the linker command line
+    /lib64/libdl.so.2: could not read symbols: Invalid operation
+
+tested on x86_64 fedora 13.

+Subject: ipmi: handle run_to_completion properly in deliver_recv_msg()
+
+From: Jiri Kosina <jkosina@suse.cz>
+
+commit a747c5abc329611220f16df0bb4cf0ca4a7fdf0c upstream.
+
+If run_to_completion flag is set, it means that we are running in a
+single-threaded mode, and thus no locks are held.
+
+This fixes a deadlock when IPMI notifier is being called during panic.
