Now these systemd network units will be processed before the other units
prefixed by 80-. And the first (in lexical order) of the network files
that matches a given device is applied, all later files are ignored,

According to MISRA C:2012, suffix 'U/UL' shall be for
unsigned const value, the member of enum variable should
not be used to compare with integer variable.
Add 'U/UL' for unsigned const value in the CPU module;
Use Macro insteading of enum feature_word since the member
of feature_word is used to compare with integer variable;
Use hex number insteading of Macro in the assembly code.

The 23:16 bits in the IOAPIC version register is the highest entry in the I/O
redirection table, which is 1 smaller than the number of interrupt input
pins. But currently we use these bits directly as the number of pins.
This patch abstracts the pin count calculation code and adds 1 to the max rte

This patch introduce an option -r to let user configre minimal space left on the

the reserved space. By default, we reserve 512M on the disk. Users can configure
