identcpu: Let the hw.model be readable in capability mode

2024-01-11T14:33:16Z

On some platforms this static information can be derived directly from the CPU, and there doesn't seem much use in restricting it.

powerpc: Avoid ignoring copyin()'s return value

2024-01-02T01:12:45Z

A recent change made it possible for cpu_set_upcall() to return an error. Do that here instead of ignoring an error from copyin(). Reviewed by: jhibbits MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D43105 (cherry picked from commit bdf03b4bcc4a9aa0be503dbc64415e6b0b845fbc)

thread: Add a return value to cpu_set_upcall()

2024-01-02T01:12:45Z

Some implementations copy data to userspace, an operation which can in principle fail. In preparation for adding a __result_use_check annotation to copyin() and related functions, let implementations of cpu_set_upcall() return an error, and check for errors when copying data to user memory.

busdma: emit a warning for use of filters

2023-12-07T00:22:19Z

Filter functions are deprecated, and unused in the tree. If either of the filter or filterarg arguments to bus_dma_tag_create() are non-NULL, print a warning. This is a direct commit to stable/13.

pmap: Prefer consistent naming for loader tunable

2023-10-23T10:15:12Z

The sysctl knob 'vm.pmap.pv_entry_max' becomes a loader tunable since 7ff48af7040f (Allow a specific setting for pv entries) but is fetched from system environment 'vm.pmap.pv_entries'. That is inconsistent and obscure. This reverts 36e1b9702e21 (Correct the tunable name in the message).
