Support basic dwarf(debuginfo) based operations for uprobe events. With
this change, perf probe can analyze debuginfo of user application binary
to set up new uprobe event.
This allows perf-probe --add(with local variables, line numbers) and
--line works with -x option. (Actually, --vars has already accepted -x
option)
For example, the following command shows the probe-able lines of a given
user space function. Something that so far was only available in the
'perf probe' tool for kernel space functions:
# ./perf probe -x perf --line map__load
<map__load@/home/fedora/ksrc/linux-2.6/tools/perf/util/map.c:0>
0 int map__load(struct map *map, symbol_filter_t filter)
1 {
2 const char *name = map->dso->long_name;
int nr;
5 if (dso__loaded(map->dso, map->type))
6 return 0;
8 nr = dso__load(map->dso, map, filter);
9 if (nr < 0) {
10 if (map->dso->has_build_id) {
And this shows the available variables at the given line of the
function.
# ./perf probe -x perf --vars map__load:8
Available variables at map__load:8
@<map__load+96>
char* name
struct map* map
symbol_filter_t filter
@<map__find_symbol+112>
char* name
symbol_filter_t filter
@<map__find_symbol_by_name+136>
char* name
symbol_filter_t filter
@<map_groups__find_symbol_by_name+176>
char* name
struct map* map
symbol_filter_t filter
And lastly, we can now define probe(s) with all available
variables on the given line:
# ./perf probe -x perf --add 'map__load:8 $vars'
Added new events:
probe_perf:map__load (on map__load:8 with $vars)
probe_perf:map__load_1 (on map__load:8 with $vars)
probe_perf:map__load_2 (on map__load:8 with $vars)
probe_perf:map__load_3 (on map__load:8 with $vars)
You can now use it in all perf tools, such as:
perf record -e probe_perf:map__load_3 -aR sleep 1
Changes from previous version:
- Add examples in the patch description.
- Use .text section start address and dwarf symbol address
for calculating the offset of given symbol, instead of
searching the symbol in symtab again.
With this change, we can safely handle multiple local
function instances (e.g. scnprintf in perf).

Expand given path to absolute path in the option parser, except for a
module name.
Since realpath at later stage in processing several probe point, can be
called several times (even if currently doesn't, it can happen when we
expands the feature), it is waste of the performance.
Processing it once at the early stage can avoid that.

Hook inline data read/write, truncate, fallocate, setattr, etc.
Files need meet following 2 requirement to inline:
1) file size is not greater than MAX_INLINE_DATA;
2) file doesn't pre-allocate data blocks by fallocate().
FI_INLINE_DATA will not be set while creating a new regular inode because
most of the files are bigger than ~3.4K. Set FI_INLINE_DATA only when
data is submitted to block layer, ranther than set it while creating a new
inode, this also avoids converting data from inline to normal data block
and vice versa.
While writting inline data to inode block, the first data block should be
released if the file has a block indexed by i_addr[0].
On the other hand, when a file operation is appied to a file with inline
data, we need to test if this file can remain inline by doing this
operation, otherwise it should be convert into normal file by reserving
a new data block, copying inline data to this new block and clear
FI_INLINE_DATA flag. Because reserve a new data block here will make use
of i_addr[0], if we save inline data in i_addr[0..872], then the first
4 bytes would be overwriten. This problem can be avoided simply by
not using i_addr[0] for inline data.

The system may crash if:

- unbanked irqs are enabled
- someone will call gpio_to_irq() for GPIO from bank2 or above
Hence, fix it by not creating irq_domain if unbanked irqs are enabled
and correct gpio_to_irq_banked() to handle this properly.

It's unsafe to call IRQ chip callbacks (.irq_mask/irq_unmask/irq_ack)
from chained IRQ handler directly. Because, Davinci GPIO block is used
by different SoCs, which, in turn, have different Main IRQ controllers
(Davinci - aintc, cp-intc; Keystone - arm-gic) which may introduce
diffrent set of IRQ chip callbacks. As result, call of
gpio_irq_handler() on Keysone will simply cause crash the system,
because ARM-GIC implements .irq_eoi() instead of .irq_ack().
Hence, fix it by using Kernel chained_irq_enter/chained_irq_exit APIs as
they are intended to handle exact such cases.

Since Davinci GPIO driver is moved to support gpiolib it has to use
ARCH_NR_GPIOS (can be configured using CONFIG_ARCH_NR_GPIO Kconfig
option) configuration instead of any mach/platform specific options.
Hence, replace private DAVINCI_N_GPIO with common ARCH_NR_GPIOS. This is
safe because default value for ARCH_NR_GPIOS=256 and maximum number of
supported GPIOs for Davinci is DAVINCI_N_GPIO=144.

The per-CPU PMSU registers documented in the datasheet start at
0x22100 and the last register for CPU3 is at 0x22428. However, the DT
informations use <0x22100 0x430>, which makes the region end at
0x22530 and not 0x22430.
Moreover, looking at the datasheet, we can see that the registers for
CPU0 start at 0x22100, for CPU1 at 0x22200, for CPU2 at 0x22300 and
for CPU3 at 0x22400. It seems clear that 0x100 bytes of registers have
been used per CPU.
Therefore, this commit reduces the length of the PMSU per-CPU register
area from the incorrect 0x430 bytes to a more logical 0x400 bytes.
