+Subject: wlcore: fix 64K page support
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+commit 4a4274bf2dbbd1c7a45be0c89a1687c9d2eef4a0 upstream.
+
+In the stable linux-3.16 branch, I ran into a warning in the
+wlcore driver:
+
+drivers/net/wireless/ti/wlcore/spi.c: In function 'wl12xx_spi_raw_write':
+drivers/net/wireless/ti/wlcore/spi.c:315:1: error: the frame size of 12848 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
+
+Newer kernels no longer show the warning, but the bug is still there,
+as the allocation is based on the CPU page size rather than the
+actual capabilities of the hardware.
+
+This replaces the PAGE_SIZE macro with the SZ_4K macro, i.e. 4096 bytes
+per buffer.
