stable inclusion from stable-v5.11-rc1 commit 2e730cb56b2cd1626fecaf23ef1537fb24721ef2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC9GHN Reference: https://lore.kernel.org/all/20201024213535.443185-1-dwmw2@infradead.org/ -------------------------------- Fix the conditions for enabling x2apic on guests without interrupt remapping, and support 15-bit Extended Destination ID to allow 32768 CPUs without IR on hypervisors that support it. Make the I/OAPIC code generate its RTE directly from the MSI message created by the parent irqchip, and fix up a bunch of magic mask/shift macros to use bitfields for MSI messages and I/OAPIC RTEs while we're at it.
