[PATCH v2 0/2] Fixes nr_cpus bug along with irq stack bootmem allocation.

[PATCH v2 0/2] Fixes nr_cpus bug along with irq stack bootmem allocation.

[Atish Patra]

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.

Sorry, it doesn't work this way.

I've already applied your patches so you would have to send me
a relative fixup.

But I'll take care of this.
