This patch contains almost all of the remaining changes needed to make to_fetch_registers/to_store_registers/to_prepare_to_store independent of inferior_ptid. It contains only some "trivial" changes, the more complicated ones are in separate patches. gdb/ChangeLog: * i386-linux-nat.c (fetch_register, store_register, i386_linux_fetch_inferior_registers, i386_linux_store_inferior_registers): Use ptid from regcache. * ia64-linux-nat.c (ia64_linux_fetch_register, ia64_linux_store_register): Likewise. * inf-ptrace.c (inf_ptrace_fetch_register, inf_ptrace_store_register): Likewise. * m32r-linux-nat.c (m32r_linux_fetch_inferior_registers, m32r_linux_store_inferior_registers): Likewise. * m68k-bsd-nat.c (m68kbsd_fetch_inferior_registers, m68kbsd_store_inferior_registers): Likewise. * m68k-linux-nat.c (fetch_register, store_register, m68k_linux_fetch_inferior_registers, m68k_linux_store_inferior_registers): Likewise. * m88k-bsd-nat.c (m88kbsd_fetch_inferior_registers, m88kbsd_store_inferior_registers): Likewise. * mips-fbsd-nat.c (mips_fbsd_fetch_inferior_registers, mips_fbsd_store_inferior_registers): Likewise. * mips-linux-nat.c (mips64_linux_regsets_fetch_registers, mips64_linux_regsets_store_registers): Likewise. * mips-nbsd-nat.c (mipsnbsd_fetch_inferior_registers, mipsnbsd_store_inferior_registers): Likewise. * mips-obsd-nat.c (mips64obsd_fetch_inferior_registers, mips64obsd_store_inferior_registers): Likewise. * nto-procfs.c (procfs_fetch_registers, procfs_store_registers): Likewise. * ppc-fbsd-nat.c (ppcfbsd_fetch_inferior_registers, ppcfbsd_store_inferior_registers): Likewise. * ppc-linux-nat.c (ppc_linux_fetch_inferior_registers, ppc_linux_store_inferior_registers): Likewise. * ppc-nbsd-nat.c (ppcnbsd_fetch_inferior_registers, ppcnbsd_store_inferior_registers): Likewise. * ppc-obsd-nat.c (ppcobsd_fetch_registers, ppcobsd_store_registers): Likewise. * procfs.c (procfs_fetch_registers, procfs_store_registers): Likewise. * ravenscar-thread.c (ravenscar_fetch_registers, ravenscar_store_registers, ravenscar_prepare_to_store): Likewise. * record-btrace.c (record_btrace_fetch_registers, record_btrace_store_registers, record_btrace_prepare_to_store): Likewise. * remote-sim.c (gdbsim_fetch_register, gdbsim_store_register): Lookup inferior using ptid from regcache, instead of current_inferior. * remote.c (remote_fetch_registers, remote_store_registers): Use ptid from regcache. * rs6000-nat.c (fetch_register, store_register): Likewise. * s390-linux-nat.c (s390_linux_fetch_inferior_registers, s390_linux_store_inferior_registers): Likewise. * sh-nbsd-nat.c (shnbsd_fetch_inferior_registers, shnbsd_store_inferior_registers): Likewise. * sol-thread.c (sol_thread_fetch_registers, sol_thread_store_registers): Likewise. * sparc-nat.c (sparc_fetch_inferior_registers, sparc_store_inferior_registers): Likewise. * tilegx-linux-nat.c (fetch_inferior_registers, store_inferior_registers): Likewise. * vax-bsd-nat.c (vaxbsd_fetch_inferior_registers, vaxbsd_store_inferior_registers): Likewise. * xtensa-linux-nat.c (fetch_gregs, store_gregs, fetch_xtregs, store_xtregs): Likewise.
