Compile the EFI bootloader with -mfloat-abi=soft to prevent the compiler from using FPU instructions. Makes the bootloader work again after we switched clang to use -mfloat-abi=softfp by default. ok jsg@, patrick@ |

| message |
Fix fallout from i386 Meltdown preparation which is using interrupt gates now. Interrupts for dna, fpu, and f00f_redirect were not properly enabled. Thus npxintr() tried to get the kernel lock with interrupts disabled causing a deadlock in pmap_tlb_shootwait(). Enable interrupts for dna, fpu, and f00f_redirect. dna and fpu leave the kernel directly, thus they have to disable interrupts again; f00f_redirect goes through calltrap which will enable interrupts. from hshoexer@; OK mlarkin@ |
