/*
* Workarounds for running on old versions of solaris with different cross call
* interfaces. If we find xc_init_cpu() in the kernel, then just use the
* defined interfaces for xc_call() from the include file where the xc_call()
* interfaces just takes a pointer to a ulong_t array. The array must be long
* enough to hold "ncpus" bits at runtime.
* The reason for the hacks is that using the type "cpuset_t" is pretty much
* impossible from code built outside the Solaris source repository that wants
* to run on multiple releases of Solaris.
*
* For old style xc_call()s, 32 bit solaris and older 64 bit versions use
* "ulong_t" as cpuset_t.
*
* Later versions of 64 bit Solaris used: struct {ulong_t words[x];}
* where "x" depends on NCPU.
*
* We detect the difference in 64 bit support by checking the kernel value of
* max_cpuid, which always holds the compiled value of NCPU - 1.
*
* If Solaris increases NCPU to more than 256, VBox will continue to work on
* all versions of Solaris as long as the number of installed CPUs in the
* machine is <= IPRT_SOLARIS_NCPUS. If IPRT_SOLARIS_NCPUS is increased, this
* code has to be re-written some to provide compatibility with older Solaris
* which expects cpuset_t to be based on NCPU==256 -- or we discontinue
* support of old Nevada/S10.
