2013-04-12mmc: mxcmmc: enable DMA support on mpc512xAnatolij Gustschin
Add SDHC DMA channel description to the mpc512x device tree to enable slave channel requesting in the mxcmmc driver. mpc512x DMA engine doesn't support endianness conversion when reading/writing data from peripheral's FIFO, so we have to swap data buffers before each DMA write and after each DMA read transfer manually. Since chained SDHC DMA transfers are not supported on mpc512x, limit 'max_segs' tunable parameter to one and initialise it to 64 only when running on i.MX platforms.

2013-04-11kvm/ppc/e500: eliminate tlb_refsScott Wood
Commit 523f0e5421c12610527c620b983b443f329e3a32 ("KVM: PPC: E500: Explicitly mark shadow maps invalid") began using E500_TLB_VALID for guest TLB1 entries, and skipping invalidations if it's not set. However, when E500_TLB_VALID was set for such entries, it was on a fake local ref, and so the invalidations never happen. gtlb_privs is documented as being only for guest TLB0, though we already violate that with E500_TLB_BITMAP. Now that we have MMU notifiers, and thus don't need to actually retain a reference to the mapped pages, get rid of tlb_refs, and use gtlb_privs for E500_TLB_VALID in TLB1. Since we can have more than one host TLB entry for a given tlbe_ref, be careful not to clear existing flags that are relevant to other host TLB entries when preparing a new host TLB entry.

2013-04-11kvm/ppc/e500: g2h_tlb1_map: clear old bit before setting new bitScott Wood
It's possible that we're using the same host TLB1 slot to map (a presumably different portion of) the same guest TLB1 entry. Clear the bit in the map before setting it, so that if the esels are the same the bit will remain set.

Add one to esel values in h2g_tlb1_rmap, so that "no mapping" can be distinguished from "esel 0". Note that we're not saved by the fact that host esel 0 is reserved for non-KVM use, because KVM host esel numbering is not the raw host numbering (see to_htlb1_esel).

2013-04-08powerpc: pSeries_lpar_hpte_remove fails from Adjunct partition being ↵Michael Wolf
performed before the ANDCOND test Some versions of pHyp will perform the adjunct partition test before the ANDCOND test. The result of this is that H_RESOURCE can be returned and cause the BUG_ON condition to occur. The HPTE is not removed. So add a check for H_RESOURCE, it is ok if this HPTE is not removed as pSeries_lpar_hpte_remove is looking for an HPTE to remove and not a specific HPTE to remove. So it is ok to just move on to the next slot and try again. Cc: stable@vger.kernel.org Signed-off-by: Michael Wolf <mjw@linux.vnet.ibm.com> Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
