Hi,
Here is a series of patches which improves perf-probe to add
filtering features for --list,--del and --funcs. This also
includes some bugfixes and cleanups.
I've fixed some patches according to Namhyung's review(Thanks!).
E.g. --list/--funcs accepts filter rules.
# ./perf probe -l v
--funcs option is a command which should be given exclusively.
This adds PARSE_OPT_EXCUSIVE flag on --funcs (-F) option.
Without this, 'perf probe --funcs -l' just shows the list of
probes. With this, it shows error message correctly.
This also fixes the help message and the documentation.

This makes perf-probe --del option to accept filter rules
not only simple glob pattern. This simplifies the code and
improve the flexibility.
E.g. if we remove 2 different pattern events, we need 2

The task migration notifier was originally introduced in order to support
the pvclock vsyscall with non-synchronized TSC, but KVM only supports it
with synchronized TSC. Hence, on KVM the r

The kvmclock spec says that the host will increment a version field to
an odd number, then update stuff, then increment it to an even number.
The host is buggy and doesn't do this, and the result is observable
when one vcpu reads another vcpu's kvmclock data.

systems are attached/generate presence for as short as 100 ms - hence

Hi all,
Commit 6428c59a97de ("perf tools: Set JOBS based on CPU or processor")
causes weird behaviour on arm/arm64 platforms because we use the "CPU"
prefix for things like:
CPU implementer : 0x41
CPU architecture: 8
CPU variant : 0x0
CPU part: 0xd03
CPU revision: 0

Hi Linus,
ACPI for arm64 has been in development for a while now and hardware has
been available that can boot with either FDT or ACPI tables. This has
been made possible by both changes to the ACPI spec to cater for
ARM-based machines (known as "hardware-reduced" in ACPI parlance) but
also a Lina

Currently, memmap_init_zone() has all the smarts for initializing a single
page. A subset of this is required for parallel page initialisation and so
this patch breaks up the monolithic function in preparation.

__free_pages_bootmem prepares a page for release to the buddy allocator

early_pfn_in_nid() and meminit_pfn_in_nid() are small functions that are
unnecessarily visible outside memory initialisation. As well as unnecessary
visibility, it's unnecessary function call overhead when initialising pages.
This patch moves the helpers inline.

Currently we when we initialze each page struct is set as reserved upon

then only setting the bit in the reserved region.
