Tony Luck 6c57a33290 [IA64] __per_cpu_idtrs[] is a memory hog ... __per_cpu_idtrs is statically allocated ... on CONFIG_NR_CPUS=4096 systems it hogs 16MB of memory. This is way too much for a quite probably unused facility (only KVM uses dynamic TR registers). Change to an array of pointers, and allocate entries as needed on a per cpu basis. Change the name too as the __per_cpu_ prefix is confusing (this isn't a classic <linux/percpu.h> type object). Signed-off-by: Tony Luck <tony.luck@intel.com>		2010-01-07 16:10:57 -08:00
