According to the AD7150 configuration register description, bit 7 assumes value 1 when the threshold mode is fixed and 0 when it is adaptive, however, the operation that identifies this mode was considering the opposite values.
This patch renames the boolean variable to describe it correctly and properly replaces it in the places where it is used.

Fix it by putting the length check before performing memcpy().

With commit 997dd9647164 ("net: IP6 defrag: use rbtrees in nf_conntrack_reasm.c"), nf_ct_frag6_reasm() is now called from nf_ct_frag6_queue(). With this change, nf_ct_frag6_queue() can fail after the skb has been added to the fragment queue and nf_ct_frag6_gather() was adapted to handle this case.
But nf_ct_frag6_queue() can still fail before the fragment has been queued. nf_ct_frag6_gather() can't handle this case anymore, because it has no way to know if nf_ct_frag6_queue() queued the fragment before failing. If it didn't, the skb is lost as the error code is overwritten with -EINPROGRESS.
Fix this by setting -EINPROGRESS directly in nf_ct_frag6_queue(), so that nf_ct_frag6_gather() can propagate the error as is.

When fixing the skb leak introduced by the conversion to rbtree, I forgot about the special case of duplicate fragments. The condition under the 'insert_error' label isn't effective anymore as nf_ct_frg6_gather() doesn't override the returned value anymore. So duplicate fragments now get NF_DROP verdict.
To accept duplicate fragments again, handle them specially as soon as inet_frag_queue_insert() reports them. Return -EINPROGRESS which will translate to NF_STOLEN verdict, like any accepted fragment. However, such packets don't carry any new information and aren't queued, so we just drop them immediately.

[ Upstream commit ce9a53eb3dbca89e7ad86673d94ab886e9bea704 ]
There are several scenarios that keyboard can NOT wake up system from suspend, e.g., if a keyboard is depressed between system device suspend phase and device noirq suspend phase, the keyboard ISR will be called and both keyboard depress and release interrupts will be disabled, then keyboard will no longer be able to wake up system. Another scenario would be, if a keyboard is kept depressed, and then system goes into suspend, the expected behavior would be when keyboard is released, system will be waked up, but current implementation can NOT achieve that, because both depress and release interrupts are disabled in ISR, and the event check is still in progress.
To fix these issues, need to make sure keyboard's depress or release interrupt is enabled after noirq device suspend phase, this patch moves the suspend/resume callback to noirq suspend/resume phase, and enable the corresponding interrupt according to current keyboard status.

In multiple SSID cases, it takes time to prepare every AP interface to be ready in initializing phase. If a sta already knows everything it needs to join one of the APs and sends authentication to the AP which is not fully prepared at this point of time, AP's channel context could be NULL. As a result, warning message occurs.
Even worse, if the AP is under attack via tools such as MDK3 and massive authentication requests are received in a very short time, console will be hung due to kernel warning messages.
WARN_ON_ONCE() could be a better way for indicating warning messages without duplicate messages to flood the console.
Johannes: We still need to address the underlying problem, but we don't really have a good handle on it yet. Suppress the worst side-effects for now.

Stopping external metadata arrays during resync/recovery causes retries, loop of interrupting and starting reconstruction, until it hit at good moment to stop completely. While these retries curr_mark_cnt can be small- especially on HDD drives, so subtraction result can be smaller than 0. However it is casted to uint without checking. As a result of it the status bar in /proc/mdstat while stopping is strange (it jumps between 0% and 99%).
The real problem occurs here after commit 72deb455b5ec ("block: remove CONFIG_LBDAF"). Sector_div() macro has been changed, now the divisor is casted to uint32. For db = -8 the divisior(db/32-1) becomes 0.
Check if db value can be really counted and replace these macro by div64_u64() inline.

Some transceivers may comply with SFF-8472 even though they do not implement the Digital Diagnostic Monitoring (DDM) interface described in the spec. The existence of such area is specified by the 6th bit of byte 92, set to 1 if implemented.
Currently, without checking this bit, bnx2x fails trying to read sfp module's EEPROM with the follow message:
ethtool -m enP5p1s0f1 Cannot get Module EEPROM data: Input/output error
Because it fails to read the additional 256 bytes in which it is assumed to exist the DDM data.
This issue was noticed using a Mellanox Passive DAC PN 01FT738. The EEPROM data was confirmed by Mellanox as correct and similar to other Passive DACs from other manufacturers.
