  We obtain a new class of stationary axisymmetric spacetimes by using the
G\"urses-G\"ursey metric with an appropriate mass function in order to generate
a rotating core of matter that may be smoothly matched to the exterior Kerr
metric. The same stationary spacetimes may be obtained by applying a slightly
modified version of the Newman-Janis algorithm to a nonrotating spherically
symmetric seed metric. The starting spherically symmetric configuration
represents a nonisotropic de-Sitter type fluid whose radial pressure $p_r$
satisfies an state equation of the form $p_r=-\rho$, where the energy density
$\rho$ is chosen to be the Tolman type-VII energy density [R. C. Tolman, Phys.
Rev. {\bf 55}, 364 (1939)]. The resulting rotating metric is then smoothly
matched to the exterior Kerr metric, and the main properties of the obtained
geometries are investigated. All the solutions considered in the present study
are regular in the sense they are free of curvature singularities. Depending on
the relative values of the total mass $m$ and rotation parameter $a$, the
resulting stationary spacetimes represent different kinds of rotating compact
objects such as regular black holes, extremal regular black holes, and regular
starlike configurations.
