2023-03-10net: sfp: only use soft polling if we have A2h accessRussell King (Oracle)
The soft state bits are stored in the A2h memory space, and require SFF-8472 compliance. This is what our have_a2 flag tells us, so use this to indicate whether we should attempt to use the soft signals.

2023-03-10net: sfp: add A2h presence flagRussell King (Oracle)
The hwmon code wants to know when it is safe to access the A2h data stored in a separate address. We indicate that this is present when we have SFF-8472 compliance and the lack of an address-change sequence., The same conditions are also true if we want to access other controls and status in the A2h address. So let's make a flag to indicate whether we can access it, instead of repeating the conditions throughout the code. For now, only convert the hwmon code.

Horatiu Vultur says: ==================== net: lan966x: Add support for IS1 VCAP Provide the Ingress Stage 1 (IS1) VCAP (Versatile Content-Aware Processor) support for the Lan966x platform. The IS1 VCAP has 3 lookups and they are accessible with a TC chain id: - chain 1000000: IS1 Lookup 0 - chain 1100000: IS1 Lookup 1 - chain 1200000: IS1 Lookup 2 The IS1 is capable of different actions like rewrite VLAN tags, change priority of the frames, police the traffic, etc. These features will be added at a later point. The IS1 currently implements the action that allows setting the value of a PAG (Policy Association Group) key field in the frame metadata and this can be used for matching in an IS2 VCAP rule. In this way a rule in IS0 VCAP can be linked to rules in the IS2 VCAP. The linking is exposed by using the TC "goto chain" action with an offset from the IS2 chain ids. For example "goto chain 8000001" will use a PAG value of 1 to chain to a rule in IS2 lookup 0. ==================== Link: https://lore.kernel.org/r/20230307220929.834219-1-horatiu.vultur@microchip.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-03-10fbdev: Fix incorrect page mapping clearance at fb_deferred_io_release()Takashi Iwai
The recent fix for the deferred I/O by the commit 3efc61d95259 ("fbdev: Fix invalid page access after closing deferred I/O devices") caused a regression when the same fb device is opened/closed while it's being used. It resulted in a frozen screen even if something is redrawn there after the close. The breakage is because the patch was made under a wrong assumption of a single open; in the current code, fb_deferred_io_release() cleans up the page mapping of the pageref list and it calls cancel_delayed_work_sync() unconditionally, where both are no correct behavior for multiple opens. This patch adds a refcount for the opens of the device, and applies the cleanup only when all files get closed. As both fb_deferred_io_open() and _close() are called always in the fb_info lock (mutex), it's safe to use the normal int for the refcounting. Also, a useless BUG_ON() is dropped.
