Break up the percpu counter allocations into individual allocations for each disk accounting counter; this fixes an issue on large systems where we have too many replica entries to for the percpu allocator's max practical size. Also, use just one eytzinger tree for the normal set of counters and the gc counters; this simplifies accounting_gc_done() where we need the same set of counters to be present in both tables.

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 reStructuredText 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.
