+Subject: ARC: Don't use "+l" inline asm constraint
+
+From: Vineet Gupta <vgupta@synopsys.com>
+
+commit 3c7c7a2fc8811bc7097479f69acf2527693d7562 upstream.
+
+Apparenty this is coming in the way of gcc fix which inhibits the usage
+of LP_COUNT as a gpr.

+Subject: kasan: update kasan_global for gcc 7
+
+From: Dmitry Vyukov <dvyukov@google.com>
+
+commit 045d599a286bc01daa3510d59272440a17b23c2e upstream.
+
+kasan_global struct is part of compiler/runtime ABI. gcc revision
+241983 has added a new field to kasan_global struct. Update kernel
+definition of kasan_global struct to include the new field.
+
+Without this patch KASAN is broken with gcc 7.

+Subject: x86/traps: Ignore high word of regs->cs in early_fixup_exception()
+
+From: Andy Lutomirski <luto@kernel.org>
+
+commit fc0e81b2bea0ebceb71889b61d2240856141c9ee upstream.
+
+On the 80486 DX, it seems that some exceptions may leave garbage in
+the high bits of CS. This causes sporadic failures in which
+early_fixup_exception() refuses to fix up an exception.
+
+As far as I can tell, this has been buggy for a long time, but the
+problem seems to have been exacerbated by commits:
+
+ 1e02ce4cccdc ("x86: Store a per-cpu shadow copy of CR4")
+ e1bfc11c5a6f ("x86/init: Fix cr4_init_shadow() on CR4-less machines")
+
+This appears to have broken for as long as we've had early
+exception handling.
+
+[ This backport should apply to kernels from 3.4 - 4.5. ]
+
+Fixes: 4c5023a3fa2e ("x86-32: Handle exception table entries during early boot")

+Subject: zram: fix unbalanced idr management at hot removal
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 529e71e16403830ae0d737a66c55c5f360f3576b upstream.
+
+The zram hot removal code calls idr_remove() even when zram_remove()
+returns an error (typically -EBUSY). This results in a leftover at the
+device release, eventually leading to a crash when the module is
+reloaded.
+
+As described in the bug report below, the following procedure would
+cause an Oops with zram:
+
+ - provision three zram devices via modprobe zram num_devices=3
+ - configure a size for each device
+ + echo "1G" > /sys/block/$zram_name/disksize
+ - mkfs and mount zram0 only
+ - attempt to hot remove all three devices
+ + echo 2 > /sys/class/zram-control/hot_remove
+ + echo 1 > /sys/class/zram-control/hot_remove
+ + echo 0 > /sys/class/zram-control/hot_remove
+ - zram0 removal fails with EBUSY, as expected
+ - unmount zram0
+ - try zram0 hot remove again
+ + echo 0 > /sys/class/zram-control/hot_remove
+ - fails with ENODEV (unexpected)
+ - unload zram kernel module
+ + completes successfully
+ - zram0 device node still exists
+ - attempt to mount /dev/zram0
+ + mount command is killed
+ + following BUG is encountered
+
+ BUG: unable to handle kernel paging request at ffffffffa0002ba0

+
+This patch adds the proper error check in hot_remove_store() not to call
+idr_remove() unconditionally.
