Convert blkdev_open() to use bdev_open_by_dev(). To be able to propagate handle from blkdev_open() to blkdev_release() we need to stop using existence of file->private_data to determine exclusive block device opens. Use bdev_handle->mode for this purpose since file->f_flags isn't usable for this (O_EXCL is cleared from the flags during open).

2023-10-28platform/chrome: cros_ec_lpc: Separate host command and irq disableLalith Rajendran3-26/+116
Both cros host command and irq disable were moved to suspend prepare stage from late suspend recently. This is causing EC to report MKBP event timeouts during suspend stress testing. When the MKBP event timeouts happen during suspend, subsequent wakeup of AP by EC using MKBP doesn't happen properly. Move the irq disabling part back to late suspend stage which is a general suggestion from the suspend kernel documentaiton to do irq disable as late as possible.

2023-10-28clk: Fix clk gate kunit test on big-endian CPUsStephen Boyd1-15/+15
The clk gate kunit test checks that the implementation of the basic clk gate reads and writes the proper bits in an MMIO register. The implementation of the basic clk gate type uses writel() and readl() which operate on little-endian registers. This test fails on big-endian CPUs because the clk gate implementation writes to 'fake_reg' with writel(), which converts the value to be written to little-endian before storing the value in the fake register. When the test checks the bits in the fake register on a big-endian machine it falsely assumes the format of the register is also big-endian, when it is really always little-endian. Suffice to say things don't work very well. Mark 'fake_reg' as __le32 and push through endian accessor fixes wherever the value is inspected to make this test endian agnostic. There's a CLK_GATE_BIG_ENDIAN flag for big-endian MMIO devices, which this test isn't using. A follow-up patch will test with and without that flag.

2023-10-28tracing/kprobes: Fix symbol counting logic by looking at modules as wellAndrii Nakryiko1-4/+20
Recent changes to count number of matching symbols when creating a kprobe event failed to take into account kernel modules. As such, it breaks kprobes on kernel module symbols, by assuming there is no match. Fix this my calling module_kallsyms_on_each_symbol() in addition to kallsyms_on_each_match_symbol() to perform a proper counting.

2023-10-28io_uring: kiocb_done() should *not* trust ->ki_pos if ->{read,write}_iter() ↵Al Viro1-1/+1
failed ->ki_pos value is unreliable in such cases. For an obvious example, consider O_DSYNC write - we feed the data to page cache and start IO, then we make sure it's completed. Update of ->ki_pos is dealt with by the first part; failure in the second ends up with negative value returned _and_ ->ki_pos left advanced as if sync had been successful. In the same situation write(2) does not advance the file position at all.
