Some callers of __irq_set_trigger() masks all flags except trigger mode flags. This is unnecessary, ase __irq_set_trigger() already does this before usage of flags.

Commit 1bf4ddc4 ("irqdomain: Introduce irq_domain_create_{linear, tree}") introduced the use of fwnode_handle to identify the interrupt controller when calling __irq_domain_add but missed updating the kernel doc parameters for the function. Update this comment. While we are touching this code, also consolidate the declaration and assignment of of_node.

Most (if not all) code here implicitly assumes that the maximum number of IRQs per chip will be 32, and thus uses 'u32' or 'unsigned long' for many tasks (for example "struct irq_data" declares its 'mask' field as 'u32', and "struct irq_chip_generic" declares its 'installed' field as 'unsigned long') However, there is no check to verify that irqs_per_chip is <= 32. Hence, calling irq_alloc_domain_generic_chips() with a bigger value will result in unexpected results. Provide a wrapper with a MAYBE_BUILD_BUG_ON(nrirqs >= 32) to catch such cases.

According to the xlate() callback definition, the 'out_type' parameter needs to be the "linux irq type". A mask for such bits exists, IRQ_TYPE_SENSE_MASK, which is correctly applied in irq_domain_xlate_twocell() So use it for irq_domain_xlate_onetwocell() as well.

Without this patch irq_domain_disassociate() cannot properly release the interrupt. In fact, irq_map_generic_chip() checks a bit on 'gc->installed' but said bit is never cleared, only set. Commit 088f40b7 ("genirq: Generic chip: Add linear irq domain support") added irq_map_generic_chip() function and also stated "This lacks a removal function for now". This commit provides an implementation of an unmap function that can be called by irq_domain_disassociate().

This is lifted from the blk-mq code and adopted to use the affinity mask concept just introduced in the irq handling code. It tries to keep the algorithm the same as the one current used by blk-mq, but improvements like assining vectors on a per-node basis instead of just per sibling are possible with this simple move and refactoring.

Use the affinity hint in the irqdesc allocator. The hint is used to determine the node for the allocation and to set the affinity of the interrupt. If multiple interrupts are allocated (multi-MSI) then the allocator iterates over the cpumask and for each set cpu it allocates on their node and sets the initial affinity to that cpu. If a single interrupt is allocated (MSI-X) then the allocator uses the first cpu in the mask to compute the allocation node and uses the mask for the initial affinity setting. Interrupts set up this way are marked with the AFFINITY_MANAGED flag to prevent userspace from messing with their affinity settings.

overlay needs underlying fs to support d_type. Recently I put in a patch in to detect this condition and started failing mount if underlying fs did not support d_type. But this breaks existing configurations over kernel upgrade. Those who are running docker (partially broken configuration) with xfs not supporting d_type, are surprised that after kernel upgrade docker does not run anymore. https://github.com/docker/docker/issues/22937#issuecomment-229881315 So instead of erroring out, detect broken configuration and warn about it. This should allow existing docker setups to continue working after kernel upgrade.

However pte_modify for the 36 bit address space support is no affected. In that case additional bits in the final CCA mode may generate an invalid value for the CCA field. On the R10000 system where this was tracked down for example a CCA 7 has been observed, which is Uncached Accelerated. Fixed by: 1) Using the proper CCA mode for PAGE_NONE just like for all the other PAGE_* pte/pmd bits. 2) Fix the two affected variants of pte_modify. Further code inspection also shows the same issue to exist in pmd_modify which would affect huge page systems. Issue in pte_modify tracked down by Alastair Bridgewater, PAGE_NONE and pmd_modify issue found by me. The history of this goes back beyond Linus' git history. Chris Dearman's commit 35133692 ("[MIPS] Allow setting of the cache attribute at run time.") missed the opportunity to fix this but it was originally introduced in lmo commit d523832cf12007b3242e50bb77d0c9e63e0b6518 ("Missing from last commit.") and 32cc38229ac7538f2346918a09e75413e8861f87 ("New configuration option CONFIG_MIPS_UNCACHED.")
