This works\nfine but the scattering of initialization logic between the init\nfunction and allocation path is a bit confusing.\n\nThis patch makes the first chunk initialize and use minimal statically\nallocated map from pcpu_setpu_first_chunk().  The map resizing path\nstill needs to handle this specially but it\u0027s more straight-forward\nand gives more latitude to the init path.  This will ease future\nchanges.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n"
