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.

nl80211: allow multiple active scheduled scan requests 2017-04-26T21:17:38+00:00 Arend Van Spriel arend.vanspriel@broadcom.com 2017-04-21T12:05:00+00:00 ca986ad9bcd3893c8b0b4cc2cafcc8cf1554409c This patch implements the idea to have multiple scheduled scan requests running concurrently. It mainly illustrates how to deal with the incoming request from user-space in terms of backward compatibility. In order to use multiple scheduled scans user-space needs to provide a flag attribute NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is treated as a legacy scan. Drivers currently supporting scheduled scan are now indicating they support a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.
