Restrict access to PCI cfg io ports to one process
* i386/i386/io_perm.c (PCI_CFG1_START, PCI_CFG1_END, PCI_CFG2_START,
PCI_CFG2_END, IS_IN_PROTECTED_RANGE): New macros.
(taken_pci_cfg): New variable.
(io_perm_deallocate): New function.
(i386_io_perm_create): Return KERN_PROTECTION_FAILURE if requested port
range contains PCI config registers and that is already taken. Set
taken_pci_cfg to true when taking them.
* i386/i386/io_perm.h (io_perm_deallocate): New declaration.
* i386/include/mach/i386/mach_i386.defs (io_perm_t): Add
io_perm_deallocate destructor.
