+Subject: [PATCH 1/9] kbuild: move -Wunused-const-variable to W=1 warning level
+
+gcc-6 started warning by default about variables that are not
+used anywhere and that are marked 'const', generating many
+false positives in an allmodconfig build, e.g.:
+
+arch/arm/mach-davinci/board-da830-evm.c:282:20: warning: 'da830_evm_emif25_pins' defined but not used [-Wunused-const-variable=]
+arch/arm/plat-omap/dmtimer.c:958:34: warning: 'omap_timer_match' defined but not used [-Wunused-const-variable=]
+drivers/bluetooth/hci_bcm.c:625:39: warning: 'acpi_bcm_default_gpios' defined but not used [-Wunused-const-variable=]
+drivers/char/hw_random/omap-rng.c:92:18: warning: 'reg_map_omap4' defined but not used [-Wunused-const-variable=]
+drivers/devfreq/exynos/exynos5_bus.c:381:32: warning: 'exynos5_busfreq_int_pm' defined but not used [-Wunused-const-variable=]
+drivers/dma/mv_xor.c:1139:34: warning: 'mv_xor_dt_ids' defined but not used [-Wunused-const-variable=]
+
+This is similar to the existing -Wunused-but-set-variable warning
+that was added in an earlier release and that we disable by default
+now and only enable when W=1 is set, so it makes sense to do
+the same here. Once we have eliminated the majority of the
+warnings for both, we can put them back into the default list.
+
+We probably want this in backport kernels as well, to allow building
+them with gcc-6 without introducing extra warnings.

+Subject: [PATCH 3/9] ath9k: fix buffer overrun for ar9287
+
+Code that was added back in 2.6.38 has an obvious overflow
+when accessing a static array, and at the time it was added
+only a code comment was put in front of it as a reminder
+to have it reviewed properly.
+
+This has not happened, but gcc-6 now points to the specific
+overflow:
+
+drivers/net/wireless/ath/ath9k/eeprom.c: In function 'ath9k_hw_get_gain_boundaries_pdadcs':
+drivers/net/wireless/ath/ath9k/eeprom.c:483:44: error: array subscript is above array bounds [-Werror=array-bounds]
+     maxPwrT4[i] = data_9287[idxL].pwrPdg[i][4];
+                   ~~~~~~~~~~~~~~~~~~~~~~~~~^~~
+
+It turns out that the correct array length exists in the local
+'intercepts' variable of this function, so we can just use that
+instead of hardcoding '4', so this patch changes all three
+instances to use that variable. The other two instances were
+already correct, but it's more consistent this way.

+Subject: [PATCH 4/9] netfilter: Fix switch statement warnings with recent gcc.
+
+More recent GCC warns about two kinds of switch statement uses:
+
+1) Switching on an enumeration, but not having an explicit case
+   statement for all members of the enumeration.  To show the
+   compiler this is intentional, we simply add a default case
+   with nothing more than a break statement.
+
+2) Switching on a boolean value.  I think this warning is dumb
+   but nevertheless you get it wholesale with -Wswitch.
+
+This patch cures all such warnings in netfilter.
