[PATCH 00/10] target/misc: Header cleanups around "cpu.h"

[Philippe Mathieu-Daudé]

These patches are part of a big refactor cleanup
around "cpu.h". Most changes should be trivial IMHO.

Philippe Mathieu-Daudé (10):
  target/hppa/helper: Include missing "cpu.h" header
  target/hexagon: Declare hexagon_regnames[] in "cpu.h"
  target/loongarch/cpu: Remove unused "sysbus.h" header
  target/loongarch/cpu: Restrict "memory.h" header to sysemu
  target/m68k/helper: Include missing "cpu.h" header
  target/ppc/helper: Include missing "cpu.h" header
  target/ppc/internal: Restrict MMU declarations to sysemu
  target/riscv/cpu: Restrict sysemu-specific fields from CPUArchState
  target/sparc/sysemu: Remove pointless CONFIG_USER_ONLY guard
  target/xtensa/cpu: Include missing "memory.h" header

[PATCH 02/10] target/hexagon: Declare hexagon_regnames[] in "cpu.h"

[Philippe Mathieu-Daudé]

The hexagon_regnames array has TOTAL_PER_THREAD_REGS elements.
TOTAL_PER_THREAD_REGS is defined in "cpu.h". Instead of pulling
"cpu.h" in "internal.h", move the hexagon_regnames[] declaration
to "cpu.h".

Commit caac44a52a ("target/sparc: Make sparc_cpu_tlb_fill sysemu
only") restricted mmu_helper.c to system emulation. Checking
whether CONFIG_USER_ONLY is defined is now pointless.

Why is this needed?  internal.h doesn't directly include cpu.h.

If the goal is to reduce the number of places where internal.h is included, then there would be additional changes.

If the concern is the dependence on TOTAL_PER_THREAD_REGS in internal.h, just change it to
extern const char * const hexagon_regnames[];

Thanks,
Taylor

No, helper.h is multiply included.
It should probably be renamed across all target/*/.

I don't think this is correct.
I would have expected cpu.h to already be included by all users of internal.h, thus any 
formal re-inclusion of cpu.h at the top of internal.h should be a no-op.
