xocl problems on Linux 6.6

[goekce]

The patch #7899 got rid of compilation errors on >= 6.6 kernels, however I get following runtime errors on Alveo U280 programmed with the standard deployment platform (xilinx_u280_gen3x16_xdma_base_1) during boot and validation (xbutil validate):

On an 6.5 kernel I don't get these errors.

I don't have the capacity to investigate the differences between 6.5 and 6.6, however I can happily provide more details.

Hi @chvamshi-xilinx , is this something your team can take a look when we move to support new version of Linux?

Yes @maxzhen .
