Replace x86-allow-1024-cpus.patch with the patch that contains the one hunk not already applied upstream. Don't install the 'trace' alias symlink for 'perf trace'. Seems much too generic to just throw that into /usr/bin

Subject: [PATCH] lib/cpumask: Make CPUMASK_OFFSTACK usable without debug
|
|
dependency
|
|
|
|
When CPUMASK_OFFSTACK was added in 2008, it was dependent upon
|
|
DEBUG_PER_CPU_MAPS being enabled, or an architecture could select it.
|
|
The debug dependency adds additional overhead that isn't required for
|
|
operation of the feature, and we need CPUMASK_OFFSTACK to increase the
|
|
NR_CPUS value beyond 512 on x86. We drop the current dependency and make
|
|
sure SMP is set.

Use dynamic allocation for cpumask_var_t, instead of putting
|
|
them on the stack. This is a bit more expensive, but avoids
