[PATCH v4 00/28] cpu: Introduce SysemuCPUOps structure, remove watchpoin


From: Philippe Mathieu-Daudé
Subject: [PATCH v4 00/28] cpu: Introduce SysemuCPUOps structure, remove watchpoints from usermode
Date: Wed, 3 Mar 2021 22:46:40 +0100

Hi,

This series is inspired on Claudio TCG work.

Instead of separate TCG from other accelerators, here we
separate sysemu operations (system VS user).

Patches 1-6 are generic cleanups.
Patches 7-15 move from CPUClass to SysemuCPUOps
Patch   16 restricts SysemuCPUOps to sysemu
Patches 17-26 remove watchpoint code from user emulation
Patches 27-28 remove USER_ONLY #ifdef'ry from "cpu.h"

Since v3:
- SysemuCPUOps const (Richard)
- added missing xtensa #ifdef'ry
- added missing aa64/sve #ifdef'ry
- added Laurent R-b

Since v2:
- fixed lm32/unicore32
- remove USER_ONLY ifdef'ry from "cpu.h" (Claudio)

Since v1:
- Name 'sysemu' (Claudio)
- change each field progressively (Richard)

$ git backport-diff -u v3
