      riscv: Fix kasan pud population · e4fcfe6e
      Alexandre Ghiti authored
      In sv48, the kasan inner regions are not aligned on PGDIR_SIZE and then
      when we populate the kasan linear mapping region, we clear the kasan
      vmalloc region which is in the same PGD.
      
      Fix this by copying the content of the kasan early pud after allocating a
      new PGD for the first time.

      riscv: Move high_memory initialization to setup_bootmem · 625e24a5
      Alexandre Ghiti authored
      high_memory used to be initialized in mem_init, way after setup_bootmem.
      But a call to dma_contiguous_reserve in this function gives rise to the
      below warning because high_memory is equal to 0 and is used at the very
      beginning at cma_declare_contiguous_nid.
      
      It went unnoticed since the move of the kasan region redefined
      KERN_VIRT_SIZE so that it does not encompass -1 anymore.
      
      Fix this by initializing high_memory in setup_bootmem.

      riscv: Fix DEBUG_VIRTUAL false warnings · 5f763b3b
      Alexandre Ghiti authored
      KERN_VIRT_SIZE used to encompass the kernel mapping before it was
      redefined when moving the kasan mapping next to the kernel mapping to only
      match the maximum amount of physical memory.
      
      Then, kernel mapping addresses that go through __virt_to_phys are now
      declared as wrong which is not true, one can use __virt_to_phys on such
      addresses.
      
      Fix this by redefining the condition that matches wrong addresses.

      riscv: Fix config KASAN && SPARSEMEM && !SPARSE_VMEMMAP · a3d32803
      Alexandre Ghiti authored
      In order to get the pfn of a struct page* when sparsemem is enabled
      without vmemmap, the mem_section structures need to be initialized which
      happens in sparse_init.
      
      But kasan_early_init calls pfn_to_page way before sparse_init is called,
      which then tries to dereference a null mem_section pointer.
      
      Fix this by removing the usage of this function in kasan_early_init.

      cachefiles: Fix incorrect length to fallocate() · b08968f1
      David Howells authored
      When cachefiles_shorten_object() calls fallocate() to shape the cache
      file to match the DIO size, it passes the total file size it wants to
      achieve, not the amount of zeros that should be inserted.  Since this is
      meant to preallocate that amount of storage for the file, it can cause
      the cache to fill up the disk and hit ENOSPC.
      
      Fix this by passing the length actually required to go from the current
      EOF to the desired EOF.

       "Including fixes from can, xfrm, wifi, bluetooth, and netfilter.
      
        Lots of various size fixes, the length of the tag speaks for itself.
        Most of the 5.17-relevant stuff comes from xfrm, wifi and bt trees
        which had been lagging as you pointed out previously. But there's also
        a larger than we'd like portion of fixes for bugs from previous
        releases.
      
        Three more fixes still under discussion, including and xfrm revert for
        uAPI error.
      
        Current release - regressions:
      
         - iwlwifi: don't advertise TWT support, prevent FW crash
      
         - xfrm: fix the if_id check in changelink
      
         - xen/netfront: destroy queues before real_num_tx_queues is zeroed
      
         - bluetooth: fix not checking MGMT cmd pending queue, make scanning
           work again

         - bluetooth: access skb->len after null check
      
         - bluetooth: hci_sync: fix not using conn_timeout
      
         - smc: fix cleanup when register ULP fails
      
         - dsa: restore error path of dsa_tree_change_tag_proto
      
         - iwlwifi: fix build error for IWLMEI
      
         - iwlwifi: mvm: propagate error from request_ownership to the user
      
        Previous releases - regressions:
      
         - xfrm: fix pMTU regression when reported pMTU is too small
      
         - xfrm: fix TCP MSS calculation when pMTU is close to 1280
      
         - bluetooth: fix bt_skb_sendmmsg not allocating partial chunks
      
         - ipv6: ensure we call ipv6_mc_down() at most once, prevent leaks
      
         - ipv6: prevent leaks in igmp6 when input queues get full
      
         - fix up skbs delta_truesize in UDP GRO frag_list

         - xfrm: distinguishing SAs and SPs by if_id in xfrm_migrate
      
         - xfrm: fix xfrm_migrate issues when address family changes
      
         - dcb: flush lingering app table entries for unregistered devices
      
         - smc: fix unexpected SMC_CLC_DECL_ERR_REGRMB error

      The blamed commit said one thing but did another. It explains that we

      but instead it replaced it with "goto out_unlock".
      
      When DSA_NOTIFIER_TAG_PROTO fails after the first switch of a
