This constant is a possible bitflag argument for `unshare`: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/uapi/linux/sched.h?h=v6.6-rc1#n44 I am unsure about its support in Fuchsia, which is why I have not added the constant there.
...in particular for 32-bit CPUs / ports, such as 32-bit arm, i386, and powerpc. In the C header files on NetBSD, this is defined as typedef unsigned long cpuid_t; and on ILP32 CPUs, that ends up being a 32-bit quantity. Defining this as a 64-bit type wrecks havoc on our 32-bit ports when e.g. _cpuset_isset() is used (as was introduced with 1.72.0), causing immediate SEGV due to NULL pointer de-reference, as observed in rust-lang/rust#116665 So, instead, define it as ::c_ulong, and let the CPU-specific type definitions take care of the sizing.
