Special case uncore_ prefix in PMU match, to allow for shorter event
uncore specifications.
Before:
perf stat -a -e uncore_cbox/event=0x35,umask=0x1,filter_opc=0x19C/ sleep 1
After
perf stat -a -e cbox/event=0x35,umask=0x1,filter_opc=0x19C/ sleep 1
Committer tests:
# perf list uncore
List of pre-defined events (to be used in -e):
uncore_cbox_0/clockticks/ [Kernel PMU event]

uncore_imc/data_reads/ [Kernel PMU event]
uncore_imc/data_writes/ [Kernel PMU event]
# perf stat -a -e cbox_0/clockticks/ sleep 1

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
