2025-01-07arm64/mm: Replace open encodings with PXD_TABLE_BITAnshuman Khandual
[pgd|p4d]_bad() helpers have open encodings for their respective table bits which can be replaced with corresponding macros. This makes things clearer, thus improving their readability as well.

2025-01-07arm64/mm: Rename pte_mkpresent() as pte_mkvalid()Anshuman Khandual
pte_present() is no longer synonymous with pte_valid() as it also tests for pte_present_invalid() as well. Hence pte_mkpresent() is misleading, because all that does is make an entry mapped, via setting PTE_VALID. Hence rename the helper as pte_mkvalid() which reflects its functionality appropriately.

2025-01-07nvmet: handle rw's limited retry flagGuixin Liu
In some scenarios, some multipath software setup places the REQ_FAILFAST_DEV flag on I/O to prevent retries and immediately switch to other paths for issuing I/O commands. This will reflect on the NVMe read and write commands with the limited retry flag. However, the current NVMe target side does not handle the limited retry flag, and the target's underlying driver still retries the I/O. This will result in the I/O not being quickly switched to other paths, ultimately leading to increased I/O latency. When the nvme target receive an rw command with limited retry flag, handle it in block backend by setting the REQ_FAILFAST_DEV flag to bio.

2025-01-07KVM: s390: vsie: fix virtual/physical address in unpin_scb()Claudio Imbrenda
In commit 77b533411595 ("KVM: s390: VSIE: sort out virtual/physical address in pin_guest_page"), only pin_scb() has been updated. This means that in unpin_scb() a virtual address was still used directly as physical address without conversion. The resulting physical address is obviously wrong and most of the time also invalid. Since commit d0ef8d9fbebe ("KVM: s390: Use kvm_release_page_dirty() to unpin "struct page" memory"), unpin_guest_page() will directly use kvm_release_page_dirty(), instead of kvm_release_pfn_dirty(), which has since been removed. One of the checks that were performed by kvm_release_pfn_dirty() was to verify whether the page was valid at all, and silently return successfully without doing anything if the page was invalid. When kvm_release_pfn_dirty() was still used, the invalid page was thus silently ignored. Now the check is gone and the result is an Oops. This also means that when running with a V!=R kernel, the page was not released, causing a leak. The solution is simply to add the missing virt_to_phys().

2025-01-07fs: debugfs: differentiate short fops with proxy opsJohannes Berg
Geert reported that my previous short fops debugfs changes broke m68k, because it only has mandatory alignement of two, so we can't stash the "is it short" information into the pointer (as we already did with the "is it real" bit.) Instead, exploit the fact that debugfs_file_get() called on an already open file will already find that the fsdata is no longer the real fops but rather the allocated data that already distinguishes full/short ops, so only open() needs to be able to distinguish. We can achieve that by using two different open functions. Unfortunately this requires another set of full file ops, increasing the size by 536 bytes (x86-64), but that's still a reasonable trade-off given that only converting some of the wireless stack gained over 28k. This brings the total cost of this to around 1k, for wins of 28k (all x86-64).

2025-01-07afs: Fix the maximum cell name lengthDavid Howells
The kafs filesystem limits the maximum length of a cell to 256 bytes, but a problem occurs if someone actually does that: kafs tries to create a directory under /proc/net/afs/ with the name of the cell, but that fails with a warning: WARNING: CPU: 0 PID: 9 at fs/proc/generic.c:405 because procfs limits the maximum filename length to 255. However, the DNS limits the maximum lookup length and, by extension, the maximum cell name, to 255 less two (length count and trailing NUL). Fix this by limiting the maximum acceptable cellname length to 253. This also allows us to be sure we can create the "/afs/.<cell>/" mountpoint too. Further, split the YFS VL record cell name maximum to be the 256 allowed by the protocol and ignore the record retrieved by YFSVL.GetCellName if it exceeds 253.

Commit 79d2e1919a27 ("staging: gpib: fix Makefiles") uses the corresponding config symbols to let Makefiles include the driver sources appropriately in the kernel build. Unfortunately, the Makefile in the tnt4882 directory refers to the non-existing config GPIB_TNT4882. The actual config name for this driver is GPIB_NI_PCI_ISA, as can be observed in the gpib Makefile. Probably, this is caused by the subtle differences between the config names, directory names and file names in ./drivers/staging/gpib/, where often config names and directory names are identical or at least close in naming, but in this case, it is not. Change the reference in the tnt4882 Makefile from the non-existing config GPIB_TNT4882 to the existing config GPIB_NI_PCI_ISA.

2025-01-07usb-storage: Add max sectors quirk for Nokia 208Lubomir Rintel
This fixes data corruption when accessing the internal SD card in mass storage mode. I am actually not too sure why. I didn't figure a straightforward way to reproduce the issue, but i seem to get garbage when issuing a lot (over 50) of large reads (over 120 sectors) are done in a quick succession. That is, time seems to matter here -- larger reads are fine if they are done with some delay between them. But I'm not great at understanding this sort of things, so I'll assume the issue other, smarter, folks were seeing with similar phones is the same problem and I'll just put my quirk next to theirs. The "Software details" screen on the phone is as follows: V 04.06 07-08-13 RM-849 (c) Nokia TL;DR version of the device descriptor: idVendor 0x0421 Nokia Mobile Phones idProduct 0x06c2 bcdDevice 4.06 iManufacturer 1 Nokia iProduct 2 Nokia 208 The patch assumes older firmwares are broken too (I'm unable to test, but no biggie if they aren't I guess), and I have no idea if newer firmware exists.

2025-01-06bnxt_en: Fix DIM shutdownMichael Chan
DIM work will call the firmware to adjust the coalescing parameters on the RX rings. We should cancel DIM work before we call the firmware to free the RX rings. Otherwise, FW will reject the call from DIM work if the RX ring has been freed. This will generate an error message like this: bnxt_en 0000:21:00.1 ens2f1np1: hwrm req_type 0x53 seq id 0x6fca error 0x2 and cause unnecessary concern for the user. It is also possible to modify the coalescing parameters of the wrong ring if the ring has been re-allocated. To prevent this, cancel DIM work right before freeing the RX rings. We also have to add a check in NAPI poll to not schedule DIM if the RX rings are shutting down. Check that the VNIC is active before we schedule DIM. The VNIC is always disabled before we free the RX rings.

2025-01-06drm/amd/display: fix divide error in DM plane scale calcsMelissa Wen
dm_get_plane_scale doesn't take into account plane scaled size equal to zero, leading to a kernel oops due to division by zero. Fix by setting out-scale size as zero when the dst size is zero, similar to what is done by drm_calc_scale(). This issue started with the introduction of cursor ovelay mode that uses this function to assess cursor mode changes via dm_crtc_get_cursor_mode() before checking plane state.
