This is still RFC, as I had not done the --no-compress logic (or tested it).
Please see if this is OK:

Subject: [PATCH] dracut.sh: Support early microcode loading.
Implement it per Linux kernel Documentation/x86/early-microcode.txt
(from v3.11-rc0):
<start>
Early load microcode
====================
By Fenghua Yu <fenghua.yu@intel.com>
Kernel can update microcode in early phase of boot time. Loading microcode early
can fix CPU issues before they are observed during kernel boot time.
Microcode is stored in an initrd file. The microcode is read from the initrd
file and loaded to CPUs during boot time.
The format of the combined initrd image is microcode in cpio format followed by
the initrd image (maybe compressed). Kernel parses the combined initrd image
during boot time. The microcode file in cpio name space is:
on Intel: kernel/x86/microcode/GenuineIntel.bin
on AMD : kernel/x86/microcode/AuthenticAMD.bin
During BSP boot (before SMP starts), if the kernel finds the microcode file in
the initrd file, it parses the microcode and saves matching microcode in memory.
If matching microcode is found, it will be uploaded in BSP and later on in all
APs.
The cached microcode patch is applied when CPUs resume from a sleep state.
There are two legacy user space interfaces to load microcode, either through
/dev/cpu/microcode or through /sys/devices/system/cpu/microcode/reload file
in sysfs.
In addition to these two legacy methods, the early loading method described
here is the third method with which microcode can be uploaded to a system's
CPUs.
The following example script shows how to generate a new combined initrd file in
/boot/initrd-3.5.0.ucode.img with original microcode microcode.bin and
original initrd image /boot/initrd-3.5.0.img.
mkdir initrd
cd initrd
mkdir -p kernel/x86/microcode
cp ../microcode.bin kernel/x86/microcode/GenuineIntel.bin (or AuthenticAMD.bin)
find . | cpio -o -H newc >../ucode.cpio
cd ..
cat ucode.cpio /boot/initrd-3.5.0.img >/boot/initrd-3.5.0.ucode.img
<end>
That is what we do in the patch. Furthermoere there is also
an off-switch: "no-early-microcode" to disable it.

This is still RFC, as I had not done the --no-compress logic (or tested it).
Please see if this is OK:

Subject: [PATCH] dracut.sh: Support early microcode loading.
Implement it per Linux kernel Documentation/x86/early-microcode.txt
(from v3.11-rc0):
<start>
Early load microcode
====================
By Fenghua Yu <fenghua.yu@intel.com>
Kernel can update microcode in early phase of boot time. Loading microcode early
can fix CPU issues before they are observed during kernel boot time.
Microcode is stored in an initrd file. The microcode is read from the initrd
file and loaded to CPUs during boot time.
The format of the combined initrd image is microcode in cpio format followed by
the initrd image (maybe compressed). Kernel parses the combined initrd image
during boot time. The microcode file in cpio name space is:
on Intel: kernel/x86/microcode/GenuineIntel.bin
on AMD : kernel/x86/microcode/AuthenticAMD.bin
During BSP boot (before SMP starts), if the kernel finds the microcode file in
the initrd file, it parses the microcode and saves matching microcode in memory.
If matching microcode is found, it will be uploaded in BSP and later on in all
APs.
The cached microcode patch is applied when CPUs resume from a sleep state.
There are two legacy user space interfaces to load microcode, either through
/dev/cpu/microcode or through /sys/devices/system/cpu/microcode/reload file
in sysfs.
In addition to these two legacy methods, the early loading method described
here is the third method with which microcode can be uploaded to a system's
CPUs.
The following example script shows how to generate a new combined initrd file in
/boot/initrd-3.5.0.ucode.img with original microcode microcode.bin and
original initrd image /boot/initrd-3.5.0.img.
mkdir initrd
cd initrd
mkdir -p kernel/x86/microcode
cp ../microcode.bin kernel/x86/microcode/GenuineIntel.bin (or AuthenticAMD.bin)
find . | cpio -o -H newc >../ucode.cpio
cd ..
cat ucode.cpio /boot/initrd-3.5.0.img >/boot/initrd-3.5.0.ucode.img
<end>
That is what we do in the patch. Furthermoere there is also
an off-switch: "no-early-microcode" to disable it.

Subject: [PATCH] dracut.sh: Support early microcode loading.
Implement it per Linux kernel Documentation/x86/early-microcode.txt
(from v3.11-rc0):
<start>
Early load microcode
====================
By Fenghua Yu <fenghua.yu@intel.com>
Kernel can update microcode in early phase of boot time. Loading microcode early
can fix CPU issues before they are observed during kernel boot time.
Microcode is stored in an initrd file. The microcode is read from the initrd
file and loaded to CPUs during boot time.
The format of the combined initrd image is microcode in cpio format followed by
the initrd image (maybe compressed). Kernel parses the combined initrd image
during boot time. The microcode file in cpio name space is:
on Intel: kernel/x86/microcode/GenuineIntel.bin
on AMD : kernel/x86/microcode/AuthenticAMD.bin
During BSP boot (before SMP starts), if the kernel finds the microcode file in
the initrd file, it parses the microcode and saves matching microcode in memory.
If matching microcode is found, it will be uploaded in BSP and later on in all
APs.
The cached microcode patch is applied when CPUs resume from a sleep state.
There are two legacy user space interfaces to load microcode, either through
/dev/cpu/microcode or through /sys/devices/system/cpu/microcode/reload file
in sysfs.
In addition to these two legacy methods, the early loading method described
here is the third method with which microcode can be uploaded to a system's
CPUs.
The following example script shows how to generate a new combined initrd file in
/boot/initrd-3.5.0.ucode.img with original microcode microcode.bin and
original initrd image /boot/initrd-3.5.0.img.
mkdir initrd
cd initrd
mkdir -p kernel/x86/microcode
cp ../microcode.bin kernel/x86/microcode/GenuineIntel.bin (or AuthenticAMD.bin)
find . | cpio -o -H newc >../ucode.cpio
cd ..
cat ucode.cpio /boot/initrd-3.5.0.img >/boot/initrd-3.5.0.ucode.img
<end>
That is what we do in the patch. Furthermoere there is also
an off-switch: "no-early-microcode" to disable it.

That is what we do in the patch. Furthermoere there is also
an off-switch: "no-early-microcode" to disable it.

Subject: [PATCH] dracut.sh: Support early microcode loading.
Implement it per Linux kernel Documentation/x86/early-microcode.txt
(from v3.11-rc0):
<start>
Early load microcode
====================
By Fenghua Yu <fenghua.yu@intel.com>
Kernel can update microcode in early phase of boot time. Loading microcode early
can fix CPU issues before they are observed during kernel boot time.
Microcode is stored in an initrd file. The microcode is read from the initrd
file and loaded to CPUs during boot time.
The format of the combined initrd image is microcode in cpio format followed by
the initrd image (maybe compressed). Kernel parses the combined initrd image
during boot time. The microcode file in cpio name space is:
on Intel: kernel/x86/microcode/GenuineIntel.bin
on AMD : kernel/x86/microcode/AuthenticAMD.bin
During BSP boot (before SMP starts), if the kernel finds the microcode file in
the initrd file, it parses the microcode and saves matching microcode in memory.
If matching microcode is found, it will be uploaded in BSP and later on in all
APs.
The cached microcode patch is applied when CPUs resume from a sleep state.
There are two legacy user space interfaces to load microcode, either through
/dev/cpu/microcode or through /sys/devices/system/cpu/microcode/reload file
in sysfs.
In addition to these two legacy methods, the early loading method described
here is the third method with which microcode can be uploaded to a system's
CPUs.
The following example script shows how to generate a new combined initrd file in
/boot/initrd-3.5.0.ucode.img with original microcode microcode.bin and
original initrd image /boot/initrd-3.5.0.img.
mkdir initrd
cd initrd
mkdir -p kernel/x86/microcode
cp ../microcode.bin kernel/x86/microcode/GenuineIntel.bin (or AuthenticAMD.bin)
find . | cpio -o -H newc >../ucode.cpio
cd ..
cat ucode.cpio /boot/initrd-3.5.0.img >/boot/initrd-3.5.0.ucode.img
<end>
That is what we do in the patch. Furthermoere there is also
an off-switch: "no-early-microcode" to disable it.

This is still RFC, as I had not done the --no-compress logic (or tested it).
Please see if this is OK:

Subject: [PATCH] dracut.sh: Support early microcode loading.
Implement it per Linux kernel Documentation/x86/early-microcode.txt
(from v3.11-rc0):
<start>
Early load microcode
====================
By Fenghua Yu <fenghua.yu@intel.com>
Kernel can update microcode in early phase of boot time. Loading microcode early
can fix CPU issues before they are observed during kernel boot time.
Microcode is stored in an initrd file. The microcode is read from the initrd
file and loaded to CPUs during boot time.
The format of the combined initrd image is microcode in cpio format followed by
the initrd image (maybe compressed). Kernel parses the combined initrd image
during boot time. The microcode file in cpio name space is:
on Intel: kernel/x86/microcode/GenuineIntel.bin
on AMD : kernel/x86/microcode/AuthenticAMD.bin
During BSP boot (before SMP starts), if the kernel finds the microcode file in
the initrd file, it parses the microcode and saves matching microcode in memory.
If matching microcode is found, it will be uploaded in BSP and later on in all
APs.
The cached microcode patch is applied when CPUs resume from a sleep state.
There are two legacy user space interfaces to load microcode, either through
/dev/cpu/microcode or through /sys/devices/system/cpu/microcode/reload file
in sysfs.
In addition to these two legacy methods, the early loading method described
here is the third method with which microcode can be uploaded to a system's
CPUs.
The following example script shows how to generate a new combined initrd file in
/boot/initrd-3.5.0.ucode.img with original microcode microcode.bin and
original initrd image /boot/initrd-3.5.0.img.
mkdir initrd
cd initrd
mkdir -p kernel/x86/microcode
cp ../microcode.bin kernel/x86/microcode/GenuineIntel.bin (or AuthenticAMD.bin)
find . | cpio -o -H newc >../ucode.cpio
cd ..
cat ucode.cpio /boot/initrd-3.5.0.img >/boot/initrd-3.5.0.ucode.img
<end>
That is what we do in the patch. Furthermoere there is also
an off-switch: "no-early-microcode" to disable it.
