To represent the size of a single allocation, dmapool currently uses 'unsigned int' in some places and 'size_t' in other places. Standardize on 'unsigned int' to reduce overhead, but use 'size_t' when counting all the blocks in the entire pool.

dmapool originally tried to support pools without a device because dma_alloc_coherent() supports allocations without a device.

Pull more tracing updates from Steven Rostedt: - Make buffer_percent read/write. The buffer_percent file is how users can state how long to block on the tracing buffer depending on how much is in the buffer. When it hits the "buffer_percent" it will wake the task waiting on the buffer. For some reason it was set to read-only. This was not noticed because testing was done as root without SELinux, but with SELinux it will prevent even root to write to it without having CAP_DAC_OVERRIDE. - The "touched_functions" was added this merge window, but one of the reasons for adding it was not implemented. That was to show what functions were not only touched, but had either a direct trampoline attached to it, or a kprobe or live kernel patching that can "hijack" the function to run a different function. The point is to know if there's functions in the kernel that may not be beh...

Merge my x86 uaccess updates branch. The LAM ("Linear Address Masking") updates in this release made me unhappy about how "access_ok()" was done, and it actually turned out to have a couple of small bugs in it too. This is my cleanup of the code: - use the sign bit of the __user pointer rather than masking the address and checking it against the TASK_SIZE range. We already did this part for the get/put_user() side, but 'access_ok()' did the naïve "mask and range check" thing, which not only generates nasty code, but also ended up meaning that __access_ok itself didn't do a good job, and so copy_from_user_nmi() didn't get the check right. - move all the code that is 64-bit only into the 64-bit version of the header file, so that we don't unnecessarily pollute the shared x86 code and make it look like LAM might work in 32-bit too. - fix a bug in the address masking (that doesn't end up mattering: in this case the fix was to just remove the buggy code entirely). - a couple of trivial cleanups and added commentary about the access_ok() rules. * x86-uaccess-cleanup: x86-64: mm: clarify the 'positive addresses' user address rules x86: mm: remove 'sign' games from LAM untagged_addr*() macros x86: uaccess: move 32-bit and 64-bit parts into proper <asm/uaccess_N.h> header x86: mm: remove architecture-specific 'access_ok()' define x86-64: make access_ok() independent of LAM

If a function had ever had IPMODIFY or DIRECT attached to it, where this is how live kernel patching and BPF overrides work, mark them and display an "M" in the enabled_functions and touched_functions files. This can be used for debugging. If a function had been modified and later there's a bug in the code related to that function, this can be used to know if the cause is possibly from a live kernel patch or a BPF program that changed the behavior of the code. Also update the documentation on the enabled_functions and touched_functions output, as it was missing direct callers and CALL_OPS. And include this new modify attribute.

If cur_state for the powerclamp cooling device is set to the default minimum state of 0, without setting first to cur_state > 0, this results in NULL pointer access. This NULL pointer access happens in the powercap core idle-inject function idle_inject_set_duration() as there is no NULL check for idle_inject_device pointer. This pointer must be allocated by calling idle_inject_register() or idle_inject_register_full(). In the function powerclamp_set_cur_state(), idle_inject_device pointer is allocated only when the cur_state > 0. But setting 0 without changing to any other state, idle_inject_set_duration() will be called with a NULL idle_inject_device pointer. To address this, just return from powerclamp_set_cur_state() if the current cooling device state is the same as the last one. Since the power-up default cooling device state is 0, changing the state to 0 again here will return without calling idle_inject_set_duration(). Signed-off-by:

Remove the acpi_backlight=video quirk for Lenovo ThinkPad W530. This was intended to help users of the (unsupported) Nvidia binary driver, but this has been reported to cause backlight control issues for users who have the gfx configured in hybrid (dual-GPU) mode, so drop this. The Nvidia binary driver should call acpi_video_register_backlight() when necessary and this has been reported to Nvidia. Until this is fixed Nvidia binary driver users can work around this by passing "acpi_backlight=video" on the kernel commandline (with the latest 6.1.y or newer stable series, kernels < 6.1.y don't need this).
