Subject: x86, trace: Change user|kernel_page_fault to page_fault_user|kernel
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a4f61dec55c1bdebb84ba77212ebf98f7247736c;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

x86, trace: Change user|kernel_page_fault to page_fault_user|kernel

Tracepoints are named hierachially, and it makes more sense to keep a
general flow of information level from general to specific from left
to right, i.e.

	x86_exceptions.page_fault_user|kernel

rather than

	x86_exceptions.user|kernel_page_fault
