Convert code away from ->read_proc/->write_proc interfaces. Switch to
proc_create()/proc_create_data() which makes addition of proc entries
reliable wrt NULL ->proc_fops, NULL ->data and so on.
Problem with ->read_proc et al is described here commit
786d7e1612 "Fix rmmod/read/write races in
/proc entries"
This patch is part of an effort to remove the old simple procfs PAGE_SIZE
buffer interface.

This cache flush occurs when we first insert a page into the page

This patch allows using a kernel image compressed with LZMA on ARM.
Extracting the image is fairly slow, but it might be useful on machines
with a very limited amount of storage, as the size benefit is quite
significant (about 25% smaller with LZMA compared to GZIP)

perf_arch_fetch_caller_regs() is exported for the overriden x86

As a general rule, weak functions should not have their symbol

So let's export it on trace_event_perf.c as it is used by trace
events only.
This fixes:
