The first patch fixes a panic caused by nr_cpus boot parameter.
In addition to that, irq stack boot memory is allocated before
cpu_possible_mask is modified. This can lead to wastage of boot
memory if nr_cpus is set to a lower value. The second patch
addresses this issue.
v1->v2:
Fixed compilation error in the v2 1/2 when CONFIG_SMP is not set.
Atish Patra (2):
sparc64: Fix cpu_possible_mask if nr_cpus is set
sparc64: Fix irq stack bootmem allocation.
