[Minios-devel] [UNIKRAFT PATCH v3 7/7] build: Add 'isr' variant for arm64 kvm plat source files called within irq context

[Jia He <justin.he@xxxxxxx>]

'isr' variant is to be called within interrupt safe context. Typically,
traps/exception/context-switch need to be added this variant.
On arm, -mgeneral-regs-only is passed to forbid the compiler to use enhanced
CPU functions that are not saved within interrupt context (e.g., floating
point units, vector units).
