-
-Mainline commit 34737e269803 ("uaccess: add generic
-__{get,put}_kernel_nofault") in 5.18-rc1 removes HAVE_GET_KERNEL_NOFAULT
-macro as all architectures can use get_kernel_nofault() now. Check for
-existence of __get_kernel_nofault() instead and add also a version check in
-case it stops being a macro or is removed in the future.

-Subject: [PATCH] vmnet: use accessors for net_device::dev_addr
-
-Mainline commit adeef3e32146 ("net: constify netdev->dev_addr") in 5.17-rc1
-makes dev_addr member of struct net_device const but accessors should be
-used to modify it since 5.15 to make sure rbtree with hardware address list
-is updated properly.
-
-Use dev_addr_set() and __dev_addr_set() in VNetNetifSetMAC() and
-VNetNetIf_Create(). For kernels before 5.15 provide our own version of the
-accessors. As SMAC_SetMac() only reads dev_addr, constify the corresponding
-argument.

-Subject: [PATCH] vmnet: use netif_rx() on newer kernels
-
-In mainline 5.18-rc1, commit baebdf48c360 ("net: dev: Makes sure netif_rx()
-can be invoked in any context.") allows calling netif_rx() from any context
-and commit 2655926aea9b ("net: Remove netif_rx_any_context() and
-netif_rx_ni().") drops netif_rx_ni() as it is no longer needed.
-
-Replace calls of netif_rx_ni() in VNetBridgeReceiveFromVNet() and
-VNetNetIfReceive() by netif_rx() when building against kernel 5.18 and
-newer.

-Subject: [PATCH] vmnet: open code csum_and_copy_to_user on kernel >= 5.19
-
-Mainline commit 6308499b5e99 ("net: unexport csum_and_copy_{from,to}_user")
-in 5.19-rc1 unexports csum_and_copy_to_user as no in-tree module is using
-it. A clean solution would probably be rewriting the code to use iovec
-iterator as csum_and_copy_to_iter() is still exported (or perhaps
-skb_copy_and_csum_datagram() might be used instead). Anything like this
-would be way too intrusive so it would have to wait for VMware developers.
-
-For now, use the simplest solution and replace the calls to
-csum_and_copy_to_user() on 5.19 and newer with open coded implementation.
-As the optimized x86 version uses csum_partial_copy_generic() which is not
-exported on x86_64 either, copy the generic one from include/net/checksum.h
-instead. This will be less efficient but hopefully the performace hit will
-not be noticeable.
