      xen: fix logical error in tlb flushing · ce7184bd
      Alex Shi authored
      While TLB_FLUSH_ALL gets passed as 'end' argument to
      flush_tlb_others(), the Xen code was made to check its 'start'
      parameter. That may give a incorrect op.cmd to MMUEXT_INVLPG_MULTI
      instead of MMUEXT_TLB_FLUSH_MULTI. Then it causes some page can not
      be flushed from TLB.
      This patch fixed this issue.

      xen/p2m: Fix one-off error in checking the P2M tree directory. · 50e90041
      Konrad Rzeszutek Wilk authored
      We would traverse the full P2M top directory (from 0->MAX_DOMAIN_PAGES
      inclusive) when trying to figure out whether we can re-use some of the
      P2M middle leafs.
      Which meant that if the kernel was compiled with MAX_DOMAIN_PAGES=512
      we would try to use the 512th entry. Fortunately for us the p2m_top_index
      has a check for this:
       BUG_ON(pfn >= MAX_P2M_PFN);
      which we hit and saw this:
      (XEN) domain_crash_sync called from entry.S

      xen/setup: Fix one-off error when adding for-balloon PFNs to the P2M. · c96aae1f
      Konrad Rzeszutek Wilk authored
      When we are finished with return PFNs to the hypervisor, then
      populate it back, and also mark the E820 MMIO and E820 gaps
      as IDENTITY_FRAMEs, we then call P2M to set areas that can
      be used for ballooning. We were off by one, and ended up
      over-writting a P2M entry that most likely was an IDENTITY_FRAME.
      For example:
      1-1 mapping on 40000->40200
      1-1 mapping on bc558->bc5ac
      1-1 mapping on bc5b4->bc8c5
      1-1 mapping on bc8c6->bcb7c
      1-1 mapping on bcd00->100000
      Released 614 pages of unused memory
      Set 277889 page(s) to 1-1 mapping
      Populating 40200-40466 pfn range: 614 pages added
      => here we set from 40466 up to bc559 P2M tree to be
      INVALID_P2M_ENTRY. We should have done it up to bc558.
      The end result is that if anybody is trying to construct
      a PTE for PFN bc558 they end up with ~PAGE_PRESENT.

      xen/p2m: Reuse existing P2M leafs if they are filled with 1:1 PFNs or INVALID. · 250a41e0
      Konrad Rzeszutek Wilk authored
      If P2M leaf is completly packed with INVALID_P2M_ENTRY or with
      1:1 PFNs (so IDENTITY_FRAME type PFNs), we can swap the P2M leaf
      with either a p2m_missing or p2m_identity respectively. The old
      page (which was created via extend_brk or was grafted on from the
      mfn_list) can be re-used for setting new PFNs.
      This also means we can remove git commit:
      xen/p2m: Reserve 8MB of _brk space for P2M leafs when populating back
      which tried to fix this.
      and make the amount that is required to be reserved much smaller.

      xen/p2m: Reserve 8MB of _brk space for P2M leafs when populating back. · 5bc6f988
      Konrad Rzeszutek Wilk authored
      When we release pages back during bootup:
      Freeing  9d-100 pfn range: 99 pages freed
      Freeing  9cf36-9d0d2 pfn range: 412 pages freed
      Freeing  9f6bd-9f6bf pfn range: 2 pages freed
      Freeing  9f714-9f7bf pfn range: 171 pages freed
      Freeing  9f7e0-9f7ff pfn range: 31 pages freed
      Freeing  9f800-100000 pfn range: 395264 pages freed
      Released 395979 pages of unused memory
      We then try to populate those pages back. In the P2M tree however
      the space for those leafs must be reserved - as such we use extend_brk.
      We reserve 8MB of _brk space, which means we can fit over
      1048576 PFNs - which is more than we should ever need.
      Without this, on certain compilation of the kernel we would hit:
      (XEN) domain_crash_sync called from entry.S

      (XEN) Guest stack trace from rsp=ffffffff81801c98:
      .. which is extend_brk hitting a BUG_ON.
      Interestingly enough, most of the time we are not going to hit this
      b/c the _brk space is quite large (v3.5):
       ffffffff81a25000 B __brk_base
       ffffffff81e43000 B __brk_limit
      = ~4MB.
      vs earlier kernels (with this back-ported), the space is smaller:
       ffffffff81a25000 B __brk_base
       ffffffff81a7b000 B __brk_limit
      = 344 kBytes.
      where we would certainly hit this and hit extend_brk.
      Note that git commit c3d93f88
      (xen: populate correct number of pages when across mem boundary (v2))
      exposed this bug).
      [v1: Made it 8MB of _brk space instead of 4MB per Jan's suggestion]

         - Fixes and cleanups for i.MX, PL0022, OMAP and bitbang drivers.

      bcma: fix invalid PMU chip control masks · 1f03bf06
      Hauke Mehrtens authored
      Commit b9562545 ("bcma: complete workaround for BCMA43224 and
      BCM4313") introduced the wrong masks for setting the chip control
      registers - the "mask" parameter is inverse.
      It should be the mask of bits *not* changed, which is admittedly a bit
      The incorrect mask not only causes the driver to not work correctly on
      the chips affected (eg the BCM43224 on the Macbook Air 4,2) but the
      state persists over a soft reset, causing the next boot to not
      necessarily see the device correctly.
