      [IA64] __per_cpu_idtrs[] is a memory hog · 6c57a332
      Tony Luck 提交于
      __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).
