// FIXME: There's only a minor difference between x86 and Aarch64/RISC-V trap frames; the prev_irq member.
|
|
// This seems to be unnecessary (see FIXME in Processor::enter_trap),
|
|
// so investigate whether we need it and either:
|
|
// (1) Remove the member and corresponding code from x86
|
|
// (2) Implement prev_irq in the assembly stubs of Aarch64 and RISC-V
|
|
// and then use the same TrapFrame on all architectures.
