-Subject: [PATCH] x86: reduce stack requirements for send_call_func_ipi
-References: bnc#425240 FATE304266
-Patch-mainline: 2.6.28
-
-* By converting the internal x86 smp_ops function send_call_func_ipi
-    to pass a pointer to the cpumask_t variable, we greatly reduce the
-    stack space required when NR_CPUS=4096.
-
-    Further reduction will be realized when the send_IPI_mask interface
-    is changed in 2.6.28.
