    MIPS: Use struct mips_abi offsets to save FP context · 2db9ca0a
    Paul Burton authored
    When saving FP state to struct sigcontext, make use of the offsets
    provided by struct mips_abi to obtain appropriate addresses for the
    sc_fpregs & sc_fpc_csr fields of the sigcontext. This is done only for
    the native struct sigcontext in this patch (ie. for O32 in CONFIG_32BIT
    kernels or for N64 in CONFIG_64BIT kernels) but is done in preparation
    for sharing this code with compat ABIs in further patches.
