Mageia 6: MGASA-2018-0374 Moderate: Kernel-tmb Memory Leak and DoS

This kernel-tmb update is based on the upstream 4.14.69 and adds additional fixes for the L1TF and Spectre security issues. It also fixes atleast the following security issues:
Memory leak in the irda_bind function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (CVE-2018-6554).
The irda_setsockopt function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (CVE-2018-6554).
Other fixes in this update: * WireGuard has been updated to 0.0.20180904 * all SPI_INTEL_SPI config options have been disable to prevent a potential bios corrupting bug (mga#23560)
