coccinelle: alloc_cast: drop removed allocatorsgrafted

- pci_alloc_consistent() and pci_zalloc_consistent() were removed by
  commit 7968778914e5
  ("PCI: Remove the deprecated "pci-dma-compat.h" API")

- kmem_alloc() was removed by commit f078d4ea8276
  ("xfs: convert kmem_alloc() to kmalloc()")

- kmem_zalloc() was removed by commit 10634530f7ba
  ("xfs: convert kmem_zalloc() to kzalloc()")

- kmem_zone_alloc() and kmem_zone_zalloc() were removed by commit
  bae633a4a283 ("xfs: remove xfs_zone_{alloc,zalloc} helpers")

So drop them from the rules.

No functional change.

+========================
+BFS Filesystem for Linux
+========================
+
+The BFS filesystem is used by SCO UnixWare OS for the /stand slice, which
+usually contains the kernel image and a few other files required for the
+boot process.
+
+In order to access /stand partition under Linux you obviously need to
+know the partition number and the kernel must support UnixWare disk slices
+(CONFIG_UNIXWARE_DISKLABEL config option). However BFS support does not
+depend on having UnixWare disklabel support because one can also mount
+BFS filesystem via loopback::
+
+    # losetup /dev/loop0 stand.img
+    # mount -t bfs /dev/loop0 /mnt/stand
+
+where stand.img is a file containing the image of BFS filesystem.
+When you have finished using it and umounted you need to also deallocate
+/dev/loop0 device by::
+
+    # losetup -d /dev/loop0
+
+You can simplify mounting by just typing::
+
+    # mount -t bfs -o loop stand.img /mnt/stand
+
+this will allocate the first available loopback device (and load loop.o
+kernel module if necessary) automatically. If the loopback driver is not
+loaded automatically, make sure that you have compiled the module and
+that modprobe is functioning. Beware that umount will not deallocate
+/dev/loopN device if /etc/mtab file on your system is a symbolic link to
+/proc/mounts. You will need to do it manually using "-d" switch of
+losetup(8). Read losetup(8) manpage for more info.
+
+To create the BFS image under UnixWare you need to find out first which
+slice contains it. The command prtvtoc(1M) is your friend::
+
+    # prtvtoc /dev/rdsk/c0b0t0d0s0
+
+(assuming your root disk is on target=0, lun=0, bus=0, controller=0). Then you
+look for the slice with tag "STAND", which is usually slice 10. With this
+information you can use dd(1) to create the BFS image::
+
+    # umount /stand
+    # dd if=/dev/rdsk/c0b0t0d0sa of=stand.img bs=512
+
+Just in case, you can verify that you have done the right thing by checking
+the magic number::
+
+    # od -Ad -tx4 stand.img | more
+
+The first 4 bytes should be 0x1badface.
+
+If you have any patches, questions or suggestions regarding this BFS
+implementation please contact the author:
