2021-04-07ACPICA: ACPI 6.4: add SDEV secure access componentsErik Kaneda
ACPICA commit 44ca5f4f9be24bf64524cdb1de46322509319056 This entails adding an optional subtable indicating secure access components as well as two different types of secure access components (ID-based or Memory). For definitons and uses, consult the ACPI specification.

2021-04-07mtd: rawnand: Add support for secure regions in NAND memoryManivannan Sadhasivam
On a typical end product, a vendor may choose to secure some regions in the NAND memory which are supposed to stay intact between FW upgrades. The access to those regions will be blocked by a secure element like Trustzone. So the normal world software like Linux kernel should not touch these regions (including reading). The regions are declared using a NAND chip DT property, "secure-regions". So let's make use of this property in the raw NAND core and skip access to the secure regions present in a system.

For adaptive threshold events, the current value is compared with a (typically) low pass filtered version of the same signal that slowly tracks large scale changes. However, sometimes a step change can result in a large lag before the low pass filtered version begins to track the signal again. Timeouts can be used to made an instantaneous 'correction'.

2021-04-07bus: mhi: core: Remove pre_init flag used for power purposesBhaumik Bhatt
Some controllers can choose to skip preparation for power up. In that case, device context is initialized based on the pre_init flag not being set during mhi_prepare_for_power_up(). There is no reason MHI host driver should maintain and provide controllers with two separate paths for preparing MHI. Going forward, all controllers will be required to call the mhi_prepare_for_power_up() API followed by their choice of sync or async power up. This allows MHI host driver to get rid of the pre_init flag and sets up a common way for all controllers to use MHI. This also helps controllers fail early on during preparation phase in some failure cases.

2021-04-07bpf, sockmap: Fix sk->prot unhash op resetJohn Fastabend
In '4da6a196f93b1' we fixed a potential unhash loop caused when a TLS socket in a sockmap was removed from the sockmap. This happened because the unhash operation on the TLS ctx continued to point at the sockmap implementation of unhash even though the psock has already been removed. The sockmap unhash handler when a psock is removed does the following, void sock_map_unhash(struct sock *sk) { void (*saved_unhash)(struct sock *sk); struct sk_psock *psock; rcu_read_lock(); psock = sk_psock(sk); if (unlikely(!psock)) { rcu_read_unlock(); if (sk->sk_prot->unhash) sk->sk_prot->unhash(sk); return; } [...] } The unlikely() case is there to handle the case where psock is detached but the proto ops have not been updated yet. But, in the above case with TLS and removed psock we never fixed sk_prot->unhash() and unhash() points back to sock_map_unhash resulting in a loop. To fix this we added this bit of code, static inline void sk_psock_restore_proto(struct sock *sk, struct sk_psock *psock) { sk->sk_prot->unhash = psock->saved_unhash; This will set the sk_prot->unhash back to its saved value. This is the correct callback for a TLS socket that has been removed from the sock_map. Unfortunately, this also overwrites the unhash pointer for all psocks. We effectively break sockmap unhash handling for any future socks. Omitting the unhash operation will leave stale entries in the map if a socket transition through unhash, but does not do close() op. To fix set unhash correctly before calling into tls_update. This way the TLS enabled socket will point to the saved unhash() handler.

2021-04-06virtio_net: Do not pull payload in skb->headEric Dumazet
Xuan Zhuo reported that commit 3226b158e67c ("net: avoid 32 x truesize under-estimation for tiny skbs") brought a ~10% performance drop. The reason for the performance drop was that GRO was forced to chain sk_buff (using skb_shinfo(skb)->frag_list), which uses more memory but also cause packet consumers to go over a lot of overhead handling all the tiny skbs. It turns out that virtio_net page_to_skb() has a wrong strategy : It allocates skbs with GOOD_COPY_LEN (128) bytes in skb->head, then copies 128 bytes from the page, before feeding the packet to GRO stack. This was suboptimal before commit 3226b158e67c ("net: avoid 32 x truesize under-estimation for tiny skbs") because GRO was using 2 frags per MSS, meaning we were not packing MSS with 100% efficiency. Fix is to pull only the ethernet header in page_to_skb() Then, we change virtio_net_hdr_to_skb() to pull the missing headers, instead of assuming they were already pulled by callers. This fixes the performance regression, but could also allow virtio_net to accept packets with more than 128bytes of headers. Many thanks to Xuan Zhuo for his report, and his tests/help.

This commit was required because at that time, ioread/iowrite functions were sub-optimal on powerpc/32 compared to the architecture specific in_/out_ IO accessors.

2021-04-06soc: fsl: guts: fix comment syntax in fileAditya Srivastava
The opening comment mark '/**' is used for kernel-doc comments. There are certain comments in include/linux/fsl/guts.h which follows this syntax, but the content inside does not comply with kernel-doc. E.g., opening comment for "Freecale 85xx and 86xx Global Utilties register set" follows kernel-doc syntax(i.e., '/**'), but the content inside does not comply with any kernel-doc specification (function, struct, etc). This causes unwelcomed warning from kernel-doc: "warning: expecting prototype for Freecale 85xx and 86xx Global Utilties register set(). Prototype was for __FSL_GUTS_H__() instead" Replace all such comment occurrences with general comment format, i.e. '/*' to pervent kernel-doc from parsing these.

2021-04-06nvme: implement non-mdts command limitsKeith Busch
Commands that access LBA contents without a data transfer between the host historically have not had a spec defined upper limit. The driver set the queue constraints for such commands to the max data transfer size just to be safe, but this artificial constraint frequently limits devices below their capabilities. The NVMe Workgroup ratified TP4040 defines how a controller may advertise their non-MDTS limits. Use these if provided and default to the current constraints if not. Since the Dataset Management command limits are defined in logical blocks, but without a namespace to tell us the logical block size, the code defaults to the safe 512b size.

2021-04-06soundwire: add static port mapping supportSrinivas Kandagatla
Some of the SoundWire device ports are statically mapped to Controller ports during design, however there is no way to expose this information to the controller. Controllers like Qualcomm ones use this info to setup static bandwidth parameters for those ports. A generic port allocation is not possible in this cases! So this patch adds a new member m_port_map to struct sdw_slave to expose this static map.
