2024-11-22m68k: mvme147, mvme16x: Adopt rtc-m48t59 platform driverFinn Thain
Both mvme147 and mvme16x platforms have their own RTC driver implementations that duplicate functionality provided by the rtc-m48t59 driver. Adopt the rtc-m48t59 driver and remove the other ones.

2024-11-18rtc: ab-eoz9: fix abeoz9_rtc_read_alarmAlexandre Belloni
abeoz9_rtc_read_alarm assumes we always read the alarm in 12-hour mode while abeoz9_rtc_set_alarm will always set it in 24-hour mode. We could support 12-hour mode in both functions but it seems very unlikely that the RTC would be set to 12-hour mode now as the driver has been setting it to 24-hour mode for a while now. The setting is undefined at power-up and unchanged by subsequent resets which doesn't help us.

If the __rtc_read_time call fails,, the struct rtc_time tm; may contain uninitialized data, or an illegal date/time read from the RTC hardware. When calling rtc_tm_to_ktime later, the result may be a very large value (possibly KTIME_MAX).

Instead of calculating the number of full days since Sunday with (days + 4) % 7, read (and write) that to the RTC Day-of-week Time Counter register (RTC_TC_DOW). Some transformation (addition and subtraction for set/get) is still done, as this register's range is [1..7], while the tm_wday in struct tm's range is [0..6]. Please note that this was added only to set_time() and read_time() callbacks because set_alarm() and read_alarm() are setting a bit in RTC_AL_MASK to ignore DOW for RTC HW alarms for unknown reasons.

Also remove the RTC_MIN_YEAR_OFFSET addition and subtraction in callbacks set_time() and read_time() respectively, as now this is already done by the API.

Maybe we could instead have made the call sites conditional, since the callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak fallback. I'll leave that to the kvm people to argue about, this at least gets the build going for that particular config.

Pull more bcachefs updates from Kent Overstreet: "Assorted minor syzbot fixes, and for bigger stuff: Fix two disk accounting rewrite bugs: - Disk accounting keys use the version field of bkey so that journal replay can tell which updates have been applied to the btree. This is set in the transaction commit path, after we've gotten our journal reservation (and our time ordering), but the BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay uses was incorrectly skipping this for new updates generated prior to journal replay. This fixes the underlying cause of an assertion pop in disk_accounting_read. - A couple of fixes for disk accounting + device removal. Checking if acocunting replicas entries were marked in the superblock was being done at the wrong point, when deltas in the journal could still zero them out, and then additionally we'd try to add a missing replicas entry to the superblock without checking if it referred to an invalid (removed) device. A whole slew of repair fixes: - fix infinite loop in propagate_key_to_snapshot_leaves(), this fixes an infinite loop when repairing a filesystem with many snapshots - fix incorrect transaction restart handling leading to occasional "fsck counted ..." warnings - fix warning in __bch2_fsck_err() for bkey fsck errors - check_inode() in fsck now correctly checks if the filesystem was clean - there shouldn't be pending logged ops if the fs was clean, we now check for this - remove_backpointer() doesn't remove a dirent that doesn't actually point to the inode - many more fsck errors are AUTOFIX" * tag 'bcachefs-2024-09-28' of git://evilpiepirate.org/bcachefs: (35 commits) bcachefs: check_subvol_path() now prints subvol root inode bcachefs: remove_backpointer() now checks if dirent points to inode bcachefs: dirent_points_to_inode() now warns on mismatch bcachefs: Fix lost wake up bcachefs: Check for logged ops when clean bcachefs: BCH_FS_clean_recovery bcachefs: Convert disk accounting BUG_ON() to WARN_ON() bcachefs: Fix BCH_TRANS_COMMIT_skip_accounting_apply bcachefs: Check for accounting keys with bversion=0 bcachefs: rename version -> bversion bcachefs: Don't delete unlinked inodes before logged op resume bcachefs: Fix BCH_SB_ERRS() so we can reorder bcachefs: Fix fsck warnings from bkey validation bcachefs: Move transaction commit path validation to as late as possible bcachefs: Fix disk accounting attempting to mark invalid replicas entry bcachefs: Fix unlocked access to c->disk_sb.sb in bch2_replicas_entry_validate() bcachefs: Fix accounting read + device removal bcachefs: bch_accounting_mode bcachefs: fix transaction restart handling in check_extents(), check_dirents() bcachefs: kill inode_walker_entry.seen_this_pos ...

2024-09-28Reduce Coccinelle choices in string_choices.cocciJulia Lawall
The isomorphism neg_if_exp negates the test of a ?: conditional, making it unnecessary to have an explicit case for a negated test with the branches inverted. At the same time, we can disable neg_if_exp in cases where a different API function may be more suitable for a negated test. Finally, in the non-patch cases, E matches an expression with parentheses around it, so there is no need to mention () explicitly in the pattern. The () are still needed in the patch cases, because we want to drop them, if they are present. Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr>
