      sparc: Allow handling signals when stack is corrupted. · 5598473a
      David S. Miller authored
      If we can't push the pending register windows onto the user's stack,
      we disallow signal delivery even if the signal would be delivered on a
      valid seperate signal stack.
      
      Add a register window save area in the signal frame, and store any
      unsavable windows there.
      
      On sigreturn, if any windows are still queued up in the signal frame,
      try to push them back onto the stack and if that fails we kill the
      process immediately.
      
      This allows the debug/tst-longjmp_chk2 glibc test case to pass.

      sparc: fix array bounds error setting up PCIC NMI trap · 4a0342ca

      arch/sparc/kernel/pcic.c: In function 'pcic_probe':

      cc1: all warnings being treated as errors
      
      I'm not particularly familiar with sparc but t_nmi (defined in head_32.S via
      the TRAP_ENTRY macro) and pcic_nmi_trap_patch (defined in entry.S) both appear
      to be 4 instructions long and I presume from the usage that instructions are
      int sized.

      xen/x86: replace order-based range checking of M2P table by linear one · ccbcdf7c
      Jan Beulich authored
      The order-based approach is not only less efficient (requiring a shift
      and a compare, typical generated code looking like this
      
      	mov	eax, [machine_to_phys_order]
      	mov	ecx, eax
      	shr	ebx, cl
      	test	ebx, ebx
      	jnz	...
      
      whereas a direct check requires just a compare, like in
      
      	cmp	ebx, [machine_to_phys_nr]
      	jae	...
      
      ), but also slightly dangerous in the 32-on-64 case - the element
      address calculation can wrap if the next power of two boundary is
      sufficiently far away from the actual upper limit of the table, and
      hence can result in user space addresses being accessed (with it being
      unknown what may actually be mapped there).
      
      Additionally, the elimination of the mistaken use of fls() here (should
      have been __fls()) fixes a latent issue on x86-64 that would trigger
      if the code was run on a system with memory extending beyond the 44-bit
      boundary.

      KVM: uses TASKSTATS, depends on NET · df3d8ae1
      Randy Dunlap authored
      CONFIG_TASKSTATS just had a change to use netlink, including
      a change to "depends on NET".  Since "select" does not follow
      dependencies, KVM also needs to depend on NET to prevent build
      errors when CONFIG_NET is not enabled.
      
      Sample of the reported "undefined reference" build errors:
      
      taskstats.c:(.text+0x8f686): undefined reference to `nla_put'
      taskstats.c:(.text+0x8f721): undefined reference to `nla_reserve'
      taskstats.c:(.text+0x8f8fb): undefined reference to `init_net'
      taskstats.c:(.text+0x8f905): undefined reference to `netlink_unicast'
      taskstats.c:(.text+0x8f934): undefined reference to `kfree_skb'
      taskstats.c:(.text+0x8f9e9): undefined reference to `skb_clone'
      taskstats.c:(.text+0x90060): undefined reference to `__alloc_skb'
      taskstats.c:(.text+0x901e9): undefined reference to `skb_put'
      taskstats.c:(.init.text+0x4665): undefined reference to `genl_register_family'
      taskstats.c:(.init.text+0x4699): undefined reference to `genl_register_ops'
