This patch removes the dependency. Unfortunately, it now fails to build
because STD_COM_FLAGS isn't defined on most architectures. I'm not familiar

Create two new legacy regions, one for MMIO space below 1MB and
another for 64k of I/O port space. For devices of PCI class VGA
these ranges will be exposed and allow direct access to the device

Zswap is a lightweight compressed cache for swap pages. It takes
pages that are in the process of being swapped out and attempts to
compress them into a dynamically allocated RAM-based memory pool.

This patch allows users of zsmalloc to register the
allocation and free routines used by zsmalloc to obtain
more pages for the memory pool. This allows the user
more control over zsmalloc pool policy and behavior.

__free_page() are used

swap_writepage() is currently where frontswap hooks into the swap

zs_create_pool() currently takes a gfp flags argument
that is used when growing the memory pool. However
it is not used in allocating the metadata for the pool

This patch renames the supply_uV* variables to supply_uv* to avoid
CamelCase as warned by the checkpatch.pl script.

Without this patch, the SHT15 driver may fail silently with a
non-bidirectional data line and/or an input-only clock line. The patch
checks the return value of gpio_direction_* function calls, prints an
error message for void-returning functions or returns the corresponding
error code otherwise.
Commit bf4d1b5ddb78f86078ac6ae0415802d5f0c68f92 (cpuidle: support
multiple drivers) changed the number of initialized state kobjects
in cpuidle_add_state_sysfs() from device->state_count to drv->state_count,
but leaved device->state_count in cpuidle_remove_state_sysfs().

Introducing a Device Tree overlay cape manager.
Using it it is possible to support the growing cape ecosystem for
the beaglebone, without having to hack a board file for each and
every cape plug combination.
It is possible to force load capes, and also possible to remove
them if need be

This patch adds support for memory profiling using the
PEBS Load Latency facility.
Load accesses are sampled by HW and the instruction
address, data address, load latency, data source, tlb,
locked information can be saved in the sampling buffer
if using the PERF_SAMPLE_COST (for latency),
Was missing from current code yet PERF_SAMPLE_ADDR has
been present for a long time. Needed for PEBS-LL mode.

This patch extends Jiri's changes to make generic
events mapping visible via sysfs. The patch extends
the mechanism to non-generic events by allowing
the mappings to be hardcoded in strings.
This mechanism will be used by the PEBS-LL patch
later on.

Type of mapping was lost and made it hard for a tool
to distinguish code vs. data mmaps. Perf has the ability
to distinguish the two.
Use a bit in the header->misc bitmask to keep track of
the mmap type. If PERF_RECORD_MISC_MMAP_DATA is set then
the mapping is not executable (!VM_EXEC). If not

The symbol addresses in a dso have relative offsets from the start of
a mapping. So in order to ouput correct offset value from @ip, one of
them should be converted.

When loading symbols in a data mapping, ABS symbols (which has a value
of SHN_ABS in its st_shndx) failed at elf_getscn(). And it marks the
loading as a failure so already loaded symbols cannot be fixed up.
I'm not sure what should be done. Just ignore them for now. :)

This patch adds the sorting and histogram support
functions to enable profiling of memory accesses.
The following sorting orders are added:
- symbol_daddr: data address symbol (or raw address)
- dso_daddr: data address shared object
- weight: access cost
- locked: access uses locked
