Allocate smaller clones With the previous dm-crypt fixes, there is no need for the clone bios to have the same bvec size as the original - we just need to make them big enough for the remaining number of pages. The only requirement is that we clear the "out" index in convert_context, so that crypt_convert starts storing data at the right position within the clone bio.

Get rid of first_clone in dm-crypt This gets rid of first_clone, which is not really needed. Apparently, cloned bios used to share their bvec some time way in the past - this is no longer the case. Contrarily, this even hurts us if we try to create a clone off first_clone after it has completed, and crypt_endio has destroyed its bvec.

This patch replaces the single instance of kmirrord by one instance per mirror set. This change is required to avoid a deadlock in kmirrord when the persistent dirty log of a mirror itself resides on a mirror. The single instance of kmirrord then issues a sync write to the dirty log in write_bits which gets deferred to kmirrord itself later in the call chain. But kmirrord never does the deferred work because it is still waiting for the sync write_bits. _mirror_sets is removed as it no longer needed, and we always flush the workqueue before destroying it to ensure all work is complete before destroying it.

CONFIG_SLUB_DEBUG can be used to switch off the debugging and sysfs components of SLUB. Thus SLUB will be able to replace SLOB. SLUB can arrange objects in a denser way than SLOB and the code size should be minimal without debugging and sysfs support. Note that CONFIG_SLUB_DEBUG is materially different from CONFIG_SLAB_DEBUG. CONFIG_SLAB_DEBUG is used to enable slab debugging in SLAB. SLUB enables debugging via a boot parameter. SLUB debug code should always be present. CONFIG_SLUB_DEBUG can be modified in the embedded config section.

SLUB currently assumes that the cacheline size is static. However, i386 f.e. supports dynamic cache line size determination. Use cache_line_size() instead of L1_CACHE_BYTES in the allocator. That also explains the purpose of SLAB_HWCACHE_ALIGN. So we will need to keep that one around to allow dynamic aligning of objects depending on boot determination of the cache line size.

In the process of rewriting the x86 setup code, I found a number of inaccuracies and outdated recommendations in the boot protocol documentation. Revamp to make it more up to date. In particular, the common use of the heap actually requires (slightly) more than 4K of heap plus stack, which is the recommended amount in the document; currently the code compensates by being smaller than specified, but we can't assume that will be true forever. Thus, recommend that if we have a modern bzImage kernel, that the bootloader maximizes the available space. Signed-off-by: NH.
