+Subject: ARM: dts: armada-38x: Fix irq type for pca955
+
+From: Gregory CLEMENT <gregory.clement@free-electrons.com>
+
+commit 8d4514173211586c6238629b1ef1e071927735f5 upstream.
+
+As written in the datasheet the PCA955 can only handle low level irq and
+not edge irq.
+
+Without this fix the interrupt is not usable for pca955: the gpio-pca953x
+driver already set the irq type as low level which is incompatible with
+edge type, then the kernel prevents using the interrupt:
+
+"irq: type mismatch, failed to map hwirq-18 for
+/soc/internal-regs/gpio@18100!"
+
+Fixes: 928413bd859c ("ARM: mvebu: Add Armada 388 General Purpose
+Development Board support")

+Subject: ext4: fix overflow caused by missing cast in ext4_resize_fs()
+
+From: Jerry Lee <jerrylee@qnap.com>
+
+commit aec51758ce10a9c847a62a48a168f8c804c6e053 upstream.
+
+On a 32-bit platform, the value of n_blcoks_count may be wrong during
+the file system is resized to size larger than 2^32 blocks. This may
+caused the superblock being corrupted with zero blocks count.

+Subject: ext4: fix SEEK_HOLE/SEEK_DATA for blocksize < pagesize
+
+From: Jan Kara <jack@suse.cz>
+
+commit fcf5ea10992fbac3c7473a1db33d56a139333cd1 upstream.
+
+ext4_find_unwritten_pgoff() does not properly handle a situation when
+starting index is in the middle of a page and blocksize < pagesize. The
+following command shows the bug on filesystem with 1k blocksize:
+
+ xfs_io -f -c "falloc 0 4k" \
+ -c "pwrite 1k 1k" \
+ -c "pwrite 3k 1k" \
+ -c "seek -a -r 0" foo
+
+In this example, neither lseek(fd, 1024, SEEK_HOLE) nor lseek(fd, 2048,
+SEEK_DATA) will return the correct result.
+
+Fix the problem by neglecting buffers in a page before starting offset.
