Now that thread_info is similar to task_struct, its address is in r2 so CURRENT_THREAD_INFO() macro is useless. This patch removes it. This patch also moves the 'tovirt(r2, r2)' down just before the reactivation of MMU translation, so that we keep the physical address of 'current' in r2 until then. It avoids a few calls to tophys(). At the same time, as the 'cpu' field is not anymore in thread_info, TI_CPU is renamed TASK_CPU by this patch. It also allows to get rid of a couple of '#ifdef CONFIG_VIRT_CPU_ACCOUNTING_NATIVE' as ACCOUNT_CPU_USER_ENTRY() and ACCOUNT_CPU_USER_EXIT() are empty when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE is not defined.

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.
