Hi,everybody,
in entry.S there are many definations about sysytem calls
I want to know some about GET_CURRENT which is used as GET_CURRENT(%ebx) .
the defination of it is following
#define GET_CURRENT(reg) \
movl %esp, reg; \
andl $-8192, reg;
put the value of reg to esp then andl $-8192, reg;
What is this means???
Thank you
hushui
