2024-08-22spi: pxa2xx: Do not override dev->platform_data on probeAndy Shevchenko4-9/+7
The platform_data field may be supplied by legacy board code. In other cases we override it, and module remove and probe cycle will crash the kernel since it will carry a stale pointer. Fix this by supplying a third argument to the pxa2xx_spi_probe() and avoid overriding dev->platform_data.

2024-08-22octeontx2-af: Fix CPT AF register offset calculationBharat Bhushan1-12/+11
Some CPT AF registers are per LF and others are global. Translation of PF/VF local LF slot number to actual LF slot number is required only for accessing perf LF registers. CPT AF global registers access do not require any LF slot number. Also, there is no reason CPT PF/VF to know actual lf's register offset. Without this fix microcode loading will fail, VFs cannot be created and hardware is not usable.

2024-08-22net: phy: realtek: Fix setting of PHY LEDs Mode B bit on RTL8211FSava Jakovljev1-1/+2
The current implementation incorrectly sets the mode bit of the PHY chip. Bit 15 (RTL8211F_LEDCR_MODE) should not be shifted together with the configuration nibble of a LED- it should be set independently of the index of the LED being configured. As a consequence, the RTL8211F LED control is actually operating in Mode A. Fix the error by or-ing final register value to write with a const-value of RTL8211F_LEDCR_MODE, thus setting Mode bit explicitly.

2024-08-22KVM: arm64: Make ICC_*SGI*_EL1 undef in the absence of a vGICv3Marc Zyngier2-0/+13
On a system with a GICv3, if a guest hasn't been configured with GICv3 and that the host is not capable of GICv2 emulation, a write to any of the ICC_*SGI*_EL1 registers is trapped to EL2. We therefore try to emulate the SGI access, only to hit a NULL pointer as no private interrupt is allocated (no GIC, remember?). The obvious fix is to give the guest what it deserves, in the shape of a UNDEF exception.

2024-08-22KVM: arm64: Ensure canonical IPA is hugepage-aligned when handling faultOliver Upton1-1/+8
Zenghui reports that VMs backed by hugetlb pages are no longer booting after commit fd276e71d1e7 ("KVM: arm64: nv: Handle shadow stage 2 page faults"). Support for shadow stage-2 MMUs introduced the concept of a fault IPA and canonical IPA to stage-2 fault handling. These are identical in the non-nested case, as the hardware stage-2 context is always that of the canonical IPA space. Both addresses need to be hugepage-aligned when preparing to install a hugepage mapping to ensure that KVM uses the correct GFN->PFN translation and installs that at the correct IPA for the current stage-2. And now I'm feeling thirsty after all this talk of IPAs...

2024-08-22bcachefs: clear path->should_be_locked in bch2_btree_key_cache_drop()Kent Overstreet1-0/+1
bch2_btree_key_cache_drop() evicts the key cache entry - it's used when we're doing an update that bypasses the key cache, because for cache coherency reasons a key can't be in the key cache unless it also exists in the btree - i.e. creates have to bypass the cache. After evicting, the path no longer points to a key cache key, and relock() will always fail if should_be_locked is true.

2024-08-22bcachefs: setting bcachefs_effective.* xattrs is a noopKent Overstreet1-1/+11
bcachefs_effective.* xattrs show the options inherited from parent directories (as well as explicitly set); this namespace is not for setting bcachefs options. Change the .set() handler to a noop so that if e.g. rsync is copying xattrs it'll do the right thing, and only copy xattrs in the bcachefs.* namespace. We don't want to return an error, because that will cause rsync to bail out or get spammy. Signed-off-by: Kent Overstreet <[email protected]>
2024-08-22bcachefs: Fix "trying to move an extent, but nr_replicas=0"Kent Overstreet1-17/+12
data_update_init() does a bunch of complicated stuff to decide how many replicas to add, since we only want to increase an extent's durability on an explicit rereplicate, but extent pointers may be on devices with different durability settings. There was a corner case when evacuating a device that had been set to durability=0 after data had been written to it, and extents on that device had already been rereplicated - then evacuate only needs to drop pointers on that device, not move them. So the assert for !m->op.nr_replicas was spurious; this was a perfectly legitimate case that needed to be handled. Signed-off-by: Kent Overstreet <[email protected]>

The corresponding fix landed upstream through MM tree last week (commit 2e6506e1c4ee: "mm/migrate: fix deadlock in migrate_pages_batch() on large folios"), therefore large folios can be safely allowed for compressed inodes and stress tests have been running on my fleet for over 20 days without any regression. Users have explicitly requested this for months, so let's allow large folios for EROFS full cases now for wider testing. Additionally, there is a fix which addresses invalid memory accesses on a failure path triggered by fault injection and two minor cleanups to simplify the codebase.

2024-08-21s390/ap: Refine AP bus bindings complete processingHarald Freudenberger1-1/+6
With the rework of the AP bus scan and the introduction of a bindings complete completion also the timing until the userspace finally receives a AP bus binding complete uevent had increased. Unfortunately this event triggers some important jobs for preparation of KVM guests, for example the modification of card/queue masks to reassign AP resources to the alternate AP queue device driver (vfio_ap) which is the precondition for building mediated devices which may be a precondition for starting KVM guests using AP resources. This small fix now triggers the check for binding complete each time an AP device driver has registered. With this patch the bindings complete may be posted up to 30s earlier as there is no need to wait for the next AP bus scan any more.
