+Subject: btrfs: cleaner_kthread() doesn't need explicit freeze
+
+From: Jiri Kosina <jkosina@suse.cz>
+
+commit 838fe1887765f4cc679febea60d87d2a06bd300e upstream.
+
+cleaner_kthread() is not marked freezable, and therefore calling
+try_to_freeze() in its context is a pointless no-op.
+
+In addition to that, as has been clearly demonstrated by 80ad623edd2d
+("Revert "btrfs: clear PF_NOFREEZE in cleaner_kthread()"), it's perfectly
+valid / legal for cleaner_kthread() to stay scheduled out in an arbitrary
+place during suspend (in that particular example that was waiting for
+reading of extent pages), so there is no need to leave any traces of
+freezer in this kthread.
+
+Fixes: 80ad623edd2d ("Revert "btrfs: clear PF_NOFREEZE in cleaner_kthread()")
+Fixes: 696249132158 ("btrfs: clear PF_NOFREEZE in cleaner_kthread()")

+Subject: megaraid_sas: add missing curly braces in ioctl handler
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+commit 3deb9438d34a09f6796639b652a01d110aca9f75 upstream.
+
+gcc-6 found a dubious indentation in the megasas_mgmt_fw_ioctl
+function:
+
+drivers/scsi/megaraid/megaraid_sas_base.c: In function 'megasas_mgmt_fw_ioctl':
+drivers/scsi/megaraid/megaraid_sas_base.c:6658:4: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]

+drivers/scsi/megaraid/megaraid_sas_base.c:6653:3: note: ...this 'if' clause, but it is not
+ if (kbuff_arr[i])
+ ^~
+
+The code is actually correct, as there is no downside in clearing a NULL
+pointer again.
+
+This clarifies the code and avoids the warning by adding extra curly
+braces.

+Subject: sunrpc/cache: drop reference when sunrpc_cache_pipe_upcall() detects a race
+
+From: NeilBrown <neilb@suse.com>
+
+commit a6ab1e8126d205238defbb55d23661a3a5c6a0d8 upstream.
+
+sunrpc_cache_pipe_upcall() can detect a race if CACHE_PENDING is no longer
+set. In this case it aborts the queuing of the upcall.
+However it has already taken a new counted reference on "h" and
+doesn't "put" it, even though it frees the data structure holding the reference.
+
+So let's delay the "cache_get" until we know we need it.

+
+From: Caesar Wang <wxt@rock-chips.com>
+
+commit 43b4eb9fe719b107c8e5d49d1edbff0c135a42cb upstream.
+
+As the Dan report the smatch check the thermal driver warning:
+drivers/thermal/rockchip_thermal.c:551 rockchip_configure_from_dt()
+warn: impossible condition '(thermal->tshut_temp > ((~0 >> 1))) =>

+
+Although The shut_temp read from DT is u32,the temperature is currently
+represented as int not long in the thermal driver.
+Let's change to make shut_temp instead of the thermal->tshut_temp for
+the condition.

+Subject: unbreak allmodconfig KCONFIG_ALLCONFIG=...
+
+From: Al Viro <viro@ZenIV.linux.org.uk>
+
+commit 6b87b70c5339f30e3c5b32085e69625906513dc2 upstream.
+
+ Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used
+to be equivalent to make allmodconfig; these days it hardwires MODULES to n.
+In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is
+treated as if it set it to n.
+
+ Regression had been introduced by commit cfa98f ("kconfig: do not
+override symbols already set"); what happens is that conf_read_simple()
+does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and
+has conf_set_all_new_symbols() skip modules_sym.
+
+ It's pretty easy to fix - simply move that call of sym_calc_value()
+into the callers, except for the ones in KCONFIG_ALLCONFIG handling.
+Objections?
