ZRAM is a memory compression method that used for anon swap out/in,
it could help system reclaim more free memory when the applications
have consumed too much memory. So we introduce the ZRAM by kernel
modules, user could insmod it as needed.

Httpchaos need both CONFIG_NETFILTER_XT_MATCH_SOCKET and
CONFIG_NETFILTER_XT_TARGET_TPROXY, these config were aleady opened in x86, but
not on arm64, so just open it.
csig need enable support for block device writeback throttling,
so open CONFIG_BLK_WBT and CONFIG_BLK_WBT_MQ.
To sync the config to the same with x86's config, we open:
CONFIG_RT_GROUP_SCHED, CONFIG_SLUB_MEMCG_SYSFS_ON, CONFIG_BLK_CGROUP_IOLATENCY,
CONFIG_BLK_RQ_ALLOC_TIME, CONFIG_BLK_CGROUP_IOCOST, CONFIG_NET_CLS_CGROUP;
To sync the config to the same with x86's config, we close:
CONFIG_NUMA_BALANCING_DEFAULT_ENABLED, CONFIG_SLAB_MERGE_DEFAULT,
CONFIG_CMDLINE_PARTITION

SLI is used for cgroup performance monitoring, but it is not
necessary for some cases(such as running the linux without
cgroups on the embedded device). Therefor we add this
configuration to decide whether package SLI into kernel or not.

centos aarch64 has enabled these configs , and tencent os x86_64 has also enabled these configs.
The number of nodes will exceed 16(2^4) for arm64 server(such as
phytium cpu), so we should change the max number of nodes to adapt
these equipment. There is something wrong with IOMMU compatibility
of phytium CPU, so we have to set IOMMU as default passthrough mode
to avoid this isssue. And we can change the IOMMU mode by cmdline
on other arm64 hardware.

Add Altra LED driver to control NVME LED.
This driver support control LED via SPCI interface on Altra system.
Currently, it is 2-LEDs system(Activity LED, Status LED). Activity
LED is completely controlled by hardware. Status LED is controlled
by this driver.
There are 4 stages of Status LED:
- ON
- OFF
- Locate(blink at 1Hz)
- Rebuild(blink at 4Hz)
Example:
To On, Off the LED on slot 9:
1. Write the seg:bus_number corresponding to LED on slot 9 to
altra:led
echo 000b:03 > /sys/class/leds/altra:led/address
2. Write 1 to brightness attr to ON, 0 to brightness attr to OFF
echo 1 > /sys/class/leds/altra:led/brightness
echo 0 > /sys/class/leds/altra:led/brightness
To blink the LED on slot 9:
1. Write the seg:bus_number corresponding to LED on slot 9 to
altra:led
echo 000b:03 > /sys/class/leds/altra:led/address
2. Write 1 to blink attr to select Locate(blink 1Hz), or 4 to
blink attr to select Rebuild(blink 4Hz)
echo 1 > /sys/class/leds/altra:led/blink
echo 4 > /sys/class/leds/altra:led/blink
3. Write 1 to shot attr to execute blink
echo 1 > /sys/class/leds/altra:led/shot
