And commit: ("allow stripping of generated symbols under CONFIG_KALLSYMS_ALL")
9bb482476c6c9d1ae033306440c51ceac93ea80cThese stripping patches has caused a set of issues:
1) People have reported compatibility issues with binutils due to
lack of support for `--strip-unneeded-symbols' with objcopy 2.15.92.0.2
Reported by: Wenji
2) ccache and distcc no longer works as expeced

Config and control variable for mem+swap controller.
This patch adds CONFIG_CGROUP_MEM_RES_CTLR_SWAP
(memory resource controller swap extension.)For accounting swap, it's obvious that we have to use additional memory to
remember "who uses swap". This adds more overhead. So, it's better to
offer "choice" to users. This patch adds 2 choices.This patch adds 2 parameters to enable swap extension or not.

Support XIP on files unpacked from the initramfs image on NOMMU systems. This
simply requires the length of the file to be preset so that the ramfs fs can
attempt to garner sufficient contiguous storage to store the file (NOMMU mmap
can only map contiguous RAM).All the other bits to do XIP on initramfs files are present:
(1) ramfs's truncate attempts to allocate a contiguous run of pages when a
file is truncated upwards from nothing.(2) ramfs sets BDI on its files to indicate direct mapping is possible, and
that its files can be mapped for read, write and exec.(3) NOMMU mmap() will use the above bits to determine that it can do XIP.
Possibly this needs better controls, because it will _always_ try and do
XIP.One disadvantage of this very simplistic approach is that sufficient space
will be allocated to store the whole file, and not just the bit that would be
XIP'd. To deal with this, though, the initramfs unpacker would have to be
able to parse the file contents.Signed-off-by: David Howells

Right now, most of the kernel boot is strictly synchronous, such that
various hardware delays are done sequentially.In order to make the kernel boot faster, this patch introduces
infrastructure to allow doing some of the initialization steps
asynchronously, which will hide significant portions of the hardware delays
in practice.In order to not change device order and other similar observables, this
patch does NOT do full parallel initialization.Rather, it operates more in the way an out of order CPU does; the work may
be done out of order and asynchronous, but the observable effects
(instruction retiring for the CPU) are still done in the original sequence.Signed-off-by: Arjan van de Ven

The function autodetect_raid is only used by __init functions, and it refers
to __initdata, so it needs __init markings. Fixes this error:
The function autodetect_raid() references
the variable __initdata raid_noautodetect.
This is often because autodetect_raid lacks a __initdata
annotation or the annotation of raid_noautodetect is wrong.Signed-off-by: Mike Frysinger

In the past, I used the root=... command line parameter to specify the
root filesystem to the kernel. Now it seems that specifying it is not
necessary. The kernel detects the root filesystem even if the kernel
command line is empty. My root fs is on a raid1 device by the way, and I
am not using initrd for the boot process.If the kernel detects the root filesystem somehow, I think it should print
out the result of this detection, otherwise I will not know which device
has the root filesystem. Or is there an easy way to get this information
on a running system? I had a quick look at the /proc and /sys
filesystems, but haven't found anything useful there.Signed-off-by: Marton Balint

GCC has a bug with __weak alias functions: if the functions are in
the same compilation unit as their call site, GCC can decide to
inline them - and thus rob the linker of the opportunity to override
the weak alias with the real thing.So move all the IRQ handling related __weak symbols to kernel/irq/chip.c.
