mm: fix KPF_SWAPCACHE in /proc/kpageflags

Commit 6326fec1122c ("mm: Use owner_priv bit for PageSwapCache, valid when PageSwapBacked") aliased PG_swapcache to PG_owner_priv_1 (and depending on PageSwapBacked being true). As a result, the KPF_SWAPCACHE bit in '/proc/kpageflags' should now be synthesized, instead of being shown on unrelated pages which just happen to have PG_owner_priv_1 set.

>mac80211: Pass new RSSI level in CQM RSSI notificationAndrzej Zaborowski2-7/+11 Extend ieee80211_cqm_rssi_notify with a rssi_level parameter so that this information can be passed to netlink clients in the next patch, if available. Most drivers will have this value at hand. wl1251 receives events from the firmware that only tell it whether latest measurement is above or below threshold so we don't pass any value at this time (parameter is 0).

Also let's move the allocation out of the declaration block so it's easier to read. Fixes: 4a5eccaa9350 ("mac80211: Show pending txqlen in debugfs.")

This does not only simplify the code, it also allows the use of more efficient and more secure implementations, especially on platforms where SIMD ciphers have a considerable setup cost.

This makes the code more understandable, and allows platforms to implement cmac(aes) in a more secure (*) and efficient way than is typically possible when using the AES cipher directly. So replace the crypto_cipher by a crypto_shash, and update the aes_s2v() routine to call the shash interface directly. * In particular, the generic table based AES implementation is sensitive to known-plaintext timing attacks on the key, to which AES based MAC algorithms are especially vulnerable, given that their plaintext is not usually secret. Time invariant alternatives are available (e.g., based on SIMD algorithms), but may incur a setup cost that is prohibitive when operating on a single block at a time, which is why they don't usually expose the cipher API.
