If extcon provider driver is probed at late time, the extcon consumer driver get the -EPROBE_DEFER return value. It requires the inefficient handling code of -EPROBE_DEFER.

2022-05-19random: unify batched entropy implementationsJason A. Donenfeld
There are currently two separate batched entropy implementations, for u32 and u64, with nearly identical code, with the goal of avoiding unaligned memory accesses and letting the buffers be used more efficiently. Having to maintain these two functions independently is a bit of a hassle though, considering that they always need to be kept in sync. This commit factors them out into a type-generic macro, so that the expansion produces the same code as before, such that diffing the assembly shows no differences. This will also make it easier in the future to add u16 and u8 batches. This was initially tested using an always_inline function and letting gcc constant fold the type size in, but the code gen was less efficient, and in general it was more verbose and harder to follow. So this patch goes with the boring macro solution, similar to what's already done for the _wait functions in random.h. Cc: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Jason A.

2022-05-19random: move randomize_page() into mm where it belongsJason A. Donenfeld
randomize_page is an mm function. It is documented like one. It contains the history of one. It has the naming convention of one. It looks just like another very similar function in mm, randomize_stack_top(). And it has always been maintained and updated by mm people. There is no need for it to be in random.c. In the "which shape does not look like the other ones" test, pointing to randomize_page() is correct. So move randomize_page() into mm/util.c, right next to the similar randomize_stack_top() function. This commit contains no actual code changes.

2022-05-19random: remove mostly unused async readiness notifierJason A. Donenfeld
The register_random_ready_notifier() notifier is somewhat complicated, and was already recently rewritten to use notifier blocks. It is only used now by one consumer in the kernel, vsprintf.c, for which the async mechanism is really overly complex for what it actually needs. This commit removes register_random_ready_notifier() and unregister_random_ ready_notifier(), because it just adds complication with little utility, and changes vsprintf.c to just check on `!rng_is_initialized() && !rng_has_arch_random()`, which will eventually be true. Performance- wise, that code was already using a static branch, so there's basically no overhead at all to this change.

2022-05-19random: remove get_random_bytes_arch() and add rng_has_arch_random()Jason A. Donenfeld
The RNG incorporates RDRAND into its state at boot and every time it reseeds, so there's no reason for callers to use it directly. The hashing that the RNG does on it is preferable to using the bytes raw. The only current use case of get_random_bytes_arch() is vsprintf's siphash key for pointer hashing, which uses it to initialize the pointer secret earlier than usual if RDRAND is available. In order to replace this narrow use case, just expose whether RDRAND is mixed into the RNG, with a new function called rng_has_arch_random(). With that taken care of, there are no users of get_random_bytes_arch() left, so it can be removed. Later, if trust_cpu gets turned on by default (as most distros are doing), this one use of rng_has_arch_random() can probably go away as well.

2022-05-19random: move initialization functions out of hot pagesJason A. Donenfeld
Much of random.c is devoted to initializing the rng and accounting for when a sufficient amount of entropy has been added. In a perfect world, this would all happen during init, and so we could mark these functions as __init. But in reality, this isn't the case: sometimes the rng only finishes initializing some seconds after system init is finished. For this reason, at the moment, a whole host of functions that are only used relatively close to system init and then never again are intermixed with functions that are used in hot code all the time. This creates more cache misses than necessary. In order to pack the hot code closer together, this commit moves the initialization functions that can't be marked as __init into .text.unlikely by way of the __cold attribute. Of particular note is moving credit_init_bits() into a macro wrapper that inlines the crng_ready() static branch check. This avoids a function call to a nop+ret, and most notably prevents extra entropy arithmetic from being computed in mix_interrupt_randomness().

2022-05-19random: make consistent use of buf and lenJason A. Donenfeld
The current code was a mix of "nbytes", "count", "size", "buffer", "in", and so forth. Instead, let's clean this up by naming input parameters "buf" (or "ubuf") and "len", so that you always understand that you're reading this variety of function argument. Signed-off-by: Jason A.

2022-05-19random: use static branch for crng_ready()Jason A. Donenfeld
Since crng_ready() is only false briefly during initialization and then forever after becomes true, we don't need to evaluate it after, making it a prime candidate for a static branch. One complication, however, is that it changes state in a particular call to credit_init_bits(), which might be made from atomic context, which means we must kick off a workqueue to change the static key. Further complicating things, credit_init_bits() may be called sufficiently early on in system initialization such that system_wq is NULL. Fortunately, there exists the nice function execute_in_process_context(), which will immediately execute the function if !in_interrupt(), and otherwise defer it to a workqueue. During early init, before workqueues are available, in_interrupt() is always false, because interrupts haven't even been enabled yet, which means the function in that case executes immediately. Later on, after workqueues are available, in_interrupt() might be true, but in that case, the work is queued in system_wq and all goes well.

2022-05-19xen: add support for initializing xenstore later as HVM domainLuca Miccio
When running as dom0less guest (HVM domain on ARM) the xenstore event channel is available at domain creation but the shared xenstore interface page only becomes available later on. In that case, wait for a notification on the xenstore event channel, then complete the xenstore initialization later, when the shared page is actually available. The xenstore page has few extra field. Add them to the shared struct. One of the field is "connection", when the connection is ready, it is zero. If the connection is not-zero, wait for a notification.

2022-05-19thermal: k3_j72xx_bandgap: Add the bandgap driver supportKeerthy
Add VTM thermal support. In the Voltage Thermal Management Module(VTM), K3 J72XX supplies a voltage reference and a temperature sensor feature that are gathered in the band gap voltage and temperature sensor (VBGAPTS) module. The band gap provides current and voltage reference for its internal circuits and other analog IP blocks. The analog-to-digital converter (ADC) produces an output value that is proportional to the silicon temperature. Currently reading temperatures only is supported. There are no active/passive cooling agent supported. J721e SoCs have errata i2128: https://www.ti.com/lit/pdf/sprz455 The VTM Temperature Monitors (TEMPSENSORs) are trimmed during production, with the resulting values stored in software-readable registers. Software should use these register values when translating the Temperature Monitor output codes to temperature values. It has an involved workaround. Software needs to read the error codes for -40C, 30C, 125C from the efuse for each device & derive a new look up table for adc to temperature conversion. Involved calculating slopes & constants using 3 different straight line equations with adc refernce codes as the y-axis & error codes in the x-axis. -40C to 30C 30C to 125C 125C to 150C With the above 2 line equations we derive the full look-up table to workaround the errata i2128 for j721e SoC. Tested temperature reading on J721e SoC & J7200 SoC.
