Yuming Han 519a279894 tracing: use kvcalloc for tgid_map array allocation 
[ Upstream commit 6ee40511cb ]

Fail to allocate memory for tgid_map, because it requires order-6 page.
detail as:

c3 sh: page allocation failure: order:6,
   mode:0x140c0c0(GFP_KERNEL), nodemask=(null)
c3 sh cpuset=/ mems_allowed=0
c3 CPU: 3 PID: 5632 Comm: sh Tainted: G        W  O    4.14.133+ #10
c3 Hardware name: Generic DT based system

c3 [<c0279000>] (SyS_write) from [<c01079a0>](ret_fast_syscall+0x0/0x54)

Switch to use kvcalloc to avoid unexpected allocation failures.

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.
