Subject: [patch V6 22/37] x86/entry: Use idtentry for interrupts
Date: Sat, 16 May 2020 01:46:09 +0200 [thread overview]
Message-ID: <20200515235126.617248111@linutronix.de> (raw)
In-Reply-To: 20200515234547.710474468@linutronix.de
Replace the extra interrupt handling code and reuse the existing idtentry
machinery. This moves the irq stack switching on 64 bit from ASM to C code;
32bit already does the stack switching in C.
