- * sysctl_mem_hold
- *
- * Description: Wire down the callers address map on behalf of sysctl's
- * that perform their own copy operations while holding
- * locks e.g. in the paging path, which could lead to a
- * deadlock, or while holding a spinlock.
- *
- * Parameters: addr User buffer address
- * len User buffer length
- *
- * Returns: 0 Success
- * vslock:ENOMEM Insufficient physical pages to wire
- * vslock:EACCES Bad protection mode
- * vslock:EINVAL Invalid parameters
- *
- * Notes: This code is invoked for the first OID element where the
- * CTLFLAG_LOCKED is not specified for a given OID node
- * element durng OID traversal, and is held for all
- * subsequent node traversals, and only released after the
- * leaf node handler invocation is complete.
- *
- * Legacy: For legacy scyctl's provided by third party code which
- * expect funnel protection for calls into their code, this
- * routine will also take the funnel, which will also only
- * be released after the leaf node handler is complete.
- *
- * This is to support legacy 32 bit BSD KEXTs and legacy 32
- * bit single threaded filesystem KEXTs and similar code
- * which relies on funnel protection, e.g. for things like
- * FSID based sysctl's.
- *
- * NEW CODE SHOULD NOT RELY ON THIS BEHAVIOUR! IT WILL BE
- * REMOVED IN A FUTURE RELASE OF Mac OS X!
- *
- * Bugs: This routine does nothing with the new_addr and new_len
- * at present, but it should, since read from the user space
- * process adddress space which could potentially trigger
- * paging may also be occurring deep down. This is due to
- * a current limitation of the vslock() routine, which will
- * always request a wired mapping be read/write, due to not
- * taking an access mode parameter. Note that this could
- * also cause problems for output on architectures where
- * write access does not require read acccess if the current
- * mapping lacks read access.
- *
- * XXX: To be moved to kern_newsysctl.c to avoid __private_extern__
