Adrian Hunter cb08c8d591 perf scripts python: exported-sql-viewer.py: Fix Array TypeError
commit fd931b2e234a7cc451a7bbb1965d6ce623189158 upstream.

The 'Array' class is present in more than one python standard library.
In some versions of Python 3, the following error occurs:

Traceback (most recent call last):
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 4702, in <lambda>
    reports_menu.addAction(CreateAction(label, "Create a new window displaying branch events", lambda a=None,x=dbid: self.NewBranchView(x), self))
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 4727, in NewBranchView
    BranchWindow(self.glb, event_id, ReportVars(), self)
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 3208, in __init__
    self.model = LookupCreateModel(model_name, lambda: BranchModel(glb, event_id, report_vars.where_clause))
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 343, in LookupCreateModel
    model = create_fn()
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 3208, in <lambda>
    self.model = LookupCreateModel(model_name, lambda: BranchModel(glb, event_id, report_vars.where_clause))
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 3124, in __init__
    self.fetcher = SQLFetcher(glb, sql, prep, self.AddSample)
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 2658, in __init__
    self.buffer = Array(c_char, self.buffer_size, lock=False)
TypeError: abstract class

This apparently happens because Python can be inconsistent about which
class of the name 'Array' gets imported. Fix by importing explicitly by
name so that only the desired 'Array' gets imported.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
