From e8012b584fac3a1bb70cd896612c12086d28e9ff Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Tue, 16 Oct 2007 01:27:16 -0700 Subject: uml: ptrace floating point fixes Handle floating point state better in ptrace. The code now correctly distinguishes between PTRACE_[GS]ETFPREGS and PTRACE_[GS]ETFPXREGS. The FPX requests get handed off to arch-specific code because that's not generic. get_fpregs, set_fpregs, set_fpregs, and set_fpxregs needed real implementations. Something here exposed a missing include in asm/page.h, which needed linux/types.h in order to get gfp_t, so that's fixed here.
