  "message": "third_party/linux: improve kernel configuration\n\nThese configuration changes are required to boot the Metropolis kernel\nvia kexec on a PowerEdge R750.\n\nkexec needs to be enabled even if we\u0027re not using it as just using kexec\nto launch a kernel on an EFI machine requires a fixup performed only if\nthe target kernel is built with kexec enabled. Otherwise it crashes\nimmediately after mounting efivars by dereferencing a null pointer.\n\nbpfilter should be disabled because it needs a userspace helper (the\n.ko actually runs in userspacee) and we ship none of that, causing an\nerror-level log message on every boot.\nUntil we actually ship the required infrastructure disable it.\n\nirq_remap is required for x2apic, without it\nthe kernel can\u0027t even boot on that platform.\n\nintel_iommu is just a drive-by enable because the AMD IOMMU is already\nenabled and we want the protection.\n\nChange-Id: Iaf0012e8c0427114c56fc5d90a9748ebeb800a54\nReviewed-on: https://review.monogon.dev/c/monogon/+/904\nTested-by: Jenkins CI\nReviewed-by: Sergiusz Bazanski \u003cserge@monogon.tech\u003e\n",
