From: Max Filippov <jcmvbkbc@gmail.com>

3
When a breakpoint is inserted at location for which there's currently no
4
virtual to physical translation no action is taken on CPU TB cache. If a
5
TB for that virtual address already exists but is not visible ATM the
6
breakpoint won't be hit next time an instruction at that address will be
7
executed.
8
9
Flush entire CPU TB cache in breakpoint_invalidate to force
10
re-translation of all TBs for the breakpoint address.
11
12
This change fixes the following scenario:
13
- linux user application is running
14
- a breakpoint is inserted from QEMU gdbstub for a user address that is
15
not currently present in the target CPU TLB
16
- an instruction at that address is executed, but the external debugger
17
doesn't get control.

Currently, helpers can only take up to 6 arguments. This patch adds the
4
capability for up to 7 arguments. I have tested it with the Hexagon port

that I am preparing for submission.
