[PATCH v5 1/4] target: Make qemu_target_page_mask() available for *-user

[Philippe Mathieu-Daudé]

From: Ilya Leoshkevich <iii@linux.ibm.com>

Currently qemu_target_page_mask() is usable only from the softmmu
code. Make it possible to use it from the *-user code as well.

Make use of it in perf.c.

[PATCH v5 2/4] tcg: Make tb_cflags() usable from target-agnostic code

[Philippe Mathieu-Daudé]

From: Ilya Leoshkevich <iii@linux.ibm.com>

Currently tb_cflags() is defined in exec-all.h, which is not usable
from target-agnostic code. Move it to translation-block.h, which is.

[PATCH v5 3/4] accel/tcg: Remove #ifdef TARGET_I386 from perf.c

[Philippe Mathieu-Daudé]

From: Ilya Leoshkevich <iii@linux.ibm.com>

Preparation for moving perf.c to tcg/.

This affects only profiling guest code, which has code in a non-0 based
segment, e.g., 16-bit code, which is not particularly important.

[PATCH v5 4/4] accel/tcg: Move perf and debuginfo support to tcg

[Philippe Mathieu-Daudé]

From: Ilya Leoshkevich <iii@linux.ibm.com>

tcg/ should not depend on accel/tcg/, but perf and debuginfo
support provided by the latter are being used by tcg/tcg.c.

Since that's the only user, move both to tcg/.
