+Subject: [PATCH] Bluetooth: btbcm: allow btbcm_read_verbose_config to fail on
+ Apple
+
+Commit 1c8ba6d013 moved around the setup code for broadcomm chips,
+and also added btbcm_read_verbose_config() to read extra information
+about the hardware.  It's returning errors on some macbooks:
+
+Bluetooth: hci0: BCM: Read verbose config info failed (-16)
+
+Which makes us error out of the setup function.  Since this
+probe isn't critical to operate the chip, this patch just changes
+things to carry on when it fails.

+Subject: [PATCH] Enable loading of bitmaps for dm-md-raid1.
+
+This is also a temporary hack to systems with junk in the rest
+of the bitmap super (instead of zeroes) to boot. This is done by
+checking mddev->sync_super (which is exclusively set by dm-raid)
+is null.
+
+These changes also include zeroing of most bitmap pages while
+allocating so we are sure that the junk is not coming from memory.
