The x86 architecture has quite a few different ways to jump into
|
||||
kernel code. Most of these entry points are registered in
|
||||
arch/x86/kernel/traps.c and implemented in arch/x86/kernel/entry_64.S
|
||||
for 64-bit, arch/x86/kernel/entry_32.S for 32-bit and finally
|
||||
arch/x86/ia32/ia32entry.S which implements the 32-bit compatibility

arch/x86/kernel/traps.c and implemented in arch/x86/entry/entry_64.S
|

for 64-bit, arch/x86/entry/entry_32.S for 32-bit and finally
|
||||
arch/x86/entry/entry_64_compat.S which implements the 32-bit compatibility
|
||||
syscall entry points and thus provides for 32-bit processes the
|
||||
ability to execute syscalls when running on 64-bit kernels.
