2022-01-12PCI: brcmstb: Declare 'used' as bitmap, not unsigned longChristophe JAILLET1-4/+9
The 'used' field of 'struct brcm_msi' is used as a bitmap. Declare it with DECLARE_BITMAP() and adjust users accordingly. This fixes a harmless Coverity warning about array vs singleton usage. This bitmap can be used for either legacy or MSI interrupts, which require a size of BRCM_INT_PCI_MSI_LEGACY_NR or BRCM_INT_PCI_MSI_NR respectively. Add a BUILD_BUG_ON() to ensure it is large enough.

2022-01-12leds: lp55xx: initialise output direction from dtsMerlijn Wajer1-1/+3
Commit a5d3d1adc95f ("leds: lp55xx: Initialize enable GPIO direction to output") attempts to fix this, but the fix did not work since at least for the Nokia N900 the value needs to be set to HIGH, per the device tree. So rather than hardcoding the value to a potentially invalid value for some devices, let's set direction in lp55xx_init_device.

2022-01-12xfs: fix online fsck handling of v5 feature bits on secondary supersDarrick J. Wong2-27/+38
While I was auditing the code in xfs_repair that adds feature bits to existing V5 filesystems, I decided to have a look at how online fsck handles feature bits, and I found a few problems: 1) ATTR2 is added to the primary super when an xattr is set to a file, but that isn't consistently propagated to secondary supers. This isn't a corruption, merely a discrepancy that repair will fix if it ever has to restore the primary from a secondary. Hence, if we find a mismatch on a secondary, this is a preen condition, not a corruption. 2) There are more compat and ro_compat features now than there used to be, but we mask off the newer features from testing. This means we ignore inconsistencies in the INOBTCOUNT and BIGTIME features, which is wrong. Get rid of the masking and compare directly. 3) NEEDSREPAIR, when set on a secondary, is ignored by everyone. Hence a mismatch here should also be flagged for preening, and online repair should clear the flag. Right now we ignore it due to (2). 4) log_incompat features are ephemeral, since we can clear the feature bit as soon as the log no longer contains live records for a particular log feature. As such, the only copy we care about is the one in the primary super. If we find any bits set in the secondary super, we should flag that for preening, and clear the bits if the user elects to repair it. Signed-off-by: Darrick J.

2022-01-12dt-bindings: net: mdio: Drop resets/reset-names child propertiesRob Herring1-6/+0
resets/reset-names are device specific and don't belong in the MDIO bus schema. For example, it doesn't match what is defined for the "qca,ar9331-switch" binding which defines "reset-names" to be "switch" rather than "phy". Neither name is that useful IMO. Other child properties are also device specific, but those won't conflict with device schemas. Signed-off-by: Rob Herring <[email protected]> Link: https://lore.kernel.org/r/[email protected]
2022-01-12x86/entry_32: Fix segment exceptionsPeter Zijlstra4-19/+27
The LKP robot reported that commit in Fixes: caused a failure. Turns out the ldt_gdt_32 selftest turns into an infinite loop trying to clear the segment. As discovered by Sean, what happens is that PARANOID_EXIT_TO_KERNEL_MODE in the handle_exception_return path overwrites the entry stack data with the task stack data, restoring the "bad" segment value. Instead of having the exception retry the instruction, have it emulate the full instruction. Replace EX_TYPE_POP_ZERO with EX_TYPE_POP_REG which will do the equivalent of: POP %reg; MOV $imm, %reg. In order to encode the segment registers, add them as registers 8-11 for 32-bit. By setting regs->[defg]s the (nested) RESTORE_REGS will pop this value at the end of the exception handler and by increasing regs->sp, it will have skipped the stack slot. This was debugged by Sean Christopherson <[email protected]>.

When removing multiple devices in a daisy-chain, each hotplug port's reset_lock may be acquired recursively. It's never the same lock, so the lockdep splat is a false positive. Because locks at the same hierarchy level are never acquired recursively, a per-level lockdep class is sufficient to fix the lockdep warning. The choice to use one lockdep subclass per pcie-hotplug controller in the path to the root-bus was made to conserve class keys because their number is limited and the complexity grows quadratically with number of keys according to Documentation/locking/lockdep-design.rst.

2022-01-12video: vga16fb: Only probe for EGA and VGA 16 color graphic cardsJavier Martinez Canillas1-0/+24
The vga16fb framebuffer driver only supports Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) 16 color graphic cards. But it doesn't check if the adapter is one of those or if a VGA16 mode is used. This means that the driver will be probed even if a VESA BIOS Extensions (VBE) or Graphics Output Protocol (GOP) interface is used. This issue has been present for a long time but it was only exposed by commit d391c5827107 ("drivers/firmware: move x86 Generic System Framebuffers support") since the platform device registration to match the {vesa,efi}fb drivers is done later as a consequence of that change. All non-x86 architectures though treat orig_video_isVGA as a boolean so only do the supported video mode check for x86 and not for other arches.
