big endian or little endian are specific to operating system or processor?

Endianness is a difference in data representation at the hardware level and may be transparent (or not) at higher levels depending on factors such as the type of high level language used.

or in other words

Endianness is the attribute of a system that indicates whether integers are represented from left to right or right to left.endianness must be chosen every time a hardware or software architecture is designed..

endianness is NEVER defined by the operating system but at the hardware level or processor level...

E.g ARM7 processor supports both big and small ENDIAN, but default is little ENDIAN, but no OS runs in it by default....

Big or Little Endian is always Processor-specific. Neither the OS nor the Kernel has any part to do with Endian.
