The new memory allocated in acpi_table_initrd_init() is used to
copy the upgraded tables to it. So it should be mapped with
early_memunmap() instead of early_ioremap().
This is critical for ARM.

Still tracking - small update: So far with the most current esxi 6
(build 3825889 - 2016-05-12) the fix is not there yet.
Sidenote: the mpt driver seems to have learned to work around the irq
handling issues (I tested kernel 4.6.2) whereas the e1000e ethernet
driver still has trouble initializing.
Another important one is the rename regression in XFS and ext4 that
I suspect is due the VFS changes in 4.7:

In current code, we can get cpuacct data from several files,
but each file have its limit.
For example:
we can get cpu usage in user and kernel mode by cpuacct.stat,
but we can't get detail data of each cpu in above file.
we can get each cpu's kernel mode usage in cpuacct.usage_percpu_sys,

Currently we have copies of the similar code for each cpustat(system/user)
in cpuacct_stats_show(), this patch use loop instead.
Only a little cleanup.

In current code, we can get cpuacct data from several files,
but each file have its limit.
For example:
we can get cpu usage in user and kernel mode by cpuacct.stat,
but we can't get detail data of each cpu in above file.
we can get each cpu's kernel mode usage in cpuacct.usage_percpu_sys,
but we

A lot of NANDs are implementing generic features in a non-generic way,
or are providing advanced auto-detection logic where the NAND ID bytes
meaning changes with the NAND generation.
Providing this vendor specific initialization step will allow us to get
rid of the full ids in the nand_ids table

The only caller of nand_get_flash_type() (nand_scan_ident()) actually
don't use the returned nand_flash_dev pointer except for converting it to
to an error code.
Rename this function nand_detect() and make it return an integer.

Now that struct nand_chip embeds an mtd_info object we can get rid of the
mtd parameter and extract it from the chip parameter with the nand_to_mtd()
helper.

Auto-detection functions are passed a busw parameter to retrieve the actual
NAND bus width and eventually set the correct value in chip->options.
Rework the nand_get_flash_type() function to get rid of this extra
parameter and let detection code directly set the NAND_BUSWIDTH_16 flag in
chip->optio

Hello, :)
This patchset is to reimplement perf_config() for efficient config management.
Everytime perf_config() is called, perf_config() always read config files.
(i.e. user config '~/.perfconfig' and system config '$(sysconfdir)/perfconfig')
But we need to use 'struct perf_config_set config_se
Many sub-commands use perf_config() so
everytime perf_config() is called, perf_config() always read config files.
(i.e. user config '~/.perfconfig' and system config '$(sysconfdir)/perfconfig')
But we need to use the config set that already contains all config
key-value pairs to avoid this repetit
