To solve this issue, Linus implemented an alternative system call mechanism to take advantage of SYSENTER/SYSEXIT instructions provided by all Pentium II+ processors.
WebWhenever a trap or interrupt occurs, the hardware switches from user mode to kernel mode, changing the mode bit's state to 0. Thus, whenever the operating system gains control of the computer, it is in kernel mode. The system always switches to user mode by setting the mode bit to 1 before passing control to a user program.
