Subject: [PATCH 0/5] Remove onstack cpumask var usage 

Hi,

This series aims at removing on-stack cpumask var usage for sparc arch.

Generally it's preferable to avoid placing cpumasks on the stack, as
for large values of NR_CPUS these can consume significant amounts of
stack space and make stack overflows more likely.

Dawei Li (5):
  sparc/srmmu: Remove on-stack cpumask var
  sparc/irq: Remove on-stack cpumask var
  sparc/of: Remove on-stack cpumask var
  sparc/pci_msi: Remove on-stack cpumask var
  sparc: Remove on-stack cpumask var
