* x86 vDSO: ia32 vsyscall removalRoland McGrath2008-01-301-90/+0
| | | | | | | | | | | | This removes all the old vsyscall code from arch/x86/ia32/ that is no longer used because arch/x86/vdso/ code has replaced it.

* x86 vDSO: ia32 sysenter_returnRoland McGrath2008-01-301-0/+4
| | | | | | | | | | | | | | | | | | | This changes the 64-bit kernel's support for the 32-bit sysenter instruction to use stored fields rather than constants for the user-mode return address, as the 32-bit kernel does. This adds a sysenter_return field to struct thread_info, as 32-bit has. There is no observable effect from this yet. It makes the assembly code independent of the 32-bit vDSO mapping address, paving the way for making the vDSO address vary as it does on the 32-bit kernel.
