+Subject: 8250: FIX Fourth port offset of Pericom PI7C9X7954 boards
+
+From: Angelo Butti <buttiangelo@gmail.com>
+
+commit 5c31ef91c06db7800ad573174bd92be4df34ecb2 upstream.
+
+Hi,
+below patch to fix Fourth port offset of Percom PI7C9X7954 boards.
+
+I had a problem using Fourth port on a pci express serial board based on Pericom
+PI7C9X7954. Reading datasheet I notice a "special" offset assign to this port
+when used in I/O mode.
+
+Offset 0x0 -> UART 0
+Offset 0x8 -> UART 1
+Offset 0x10 -> UART 2
+Offset 0x38 -> UART 3 <<---- This don't follow a logical sequence
+
+This patch add a different init to last port, to have right offset.
+
+I check also Pericom 7952 and 7958 but that devices follow logical sequence,
+so they are ok.
+
+Regards,
+Angelo

+Subject: dm: fix to_sector() for 32bit
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: NeilBrown <neil@brown.name>
+
+commit 0bdb50c531f7377a9da80d3ce2d61f389c84cb30 upstream.
+
+A dm-raid array with devices larger than 4GB won't assemble on
+a 32 bit host since _check_data_dev_sectors() was added in 4.16.
+This is because to_sector() treats its argument as an "unsigned long"
+which is 32bits (4GB) on a 32bit host. Using "unsigned long long"
+is more correct.
+
+Kernels as early as 4.2 can have other problems due to to_sector()
+being used on the size of a device.
+
+Fixes: 0cf4503174c1 ("dm raid: add support for the MD RAID0 personality")
+cc: stable@vger.kernel.org (v4.2+)
