This patch provides a caching mechanism for the device address
extensions uid and fid on S390. For efficient sparse address allocation,
we introduce two hash tables for uid/fid which hold the address set
information per domain. Also in order to improve performance of
searching available value, we introduce our own callbacks for the two
hashtables. In this way, uid/fid is saved in hash key and hash value
could be any non-NULL pointer due to no operation on hash value. That is
also the reason why we don't introduce hash value free callback.
Pretty much assuming your hash table implementation doesn't have
any issues, because I lack the expertise to review it properly :)
Some code style issues below.

+static uint32_t virZPCIAddrCode(const void *name, uint32_t seed)
The return type and each of the function arguments should be on
separate lines, like
static uint32_t
virZPCIAddrCode(const void *name,
uint32_t seed)
[...]
+static bool virZPCIAddrEqual(const void *namea, const void *nameb)
Same.
[...]
+static void *virZPCIAddrCopy(const void *name)
Same.
[...]
+static void virZPCIAddrKeyFree(void *name)
Same.
[...]
+int
+virDomainPCIAddressSetExtensionAlloc(virDomainPCIAddressSetPtr addrs,

This should probably be
if (extFlags & VIR_PCI_ADDRESS_EXTENSION_ZPCI)
since we're dealing with flags, but given the way you end up
calling the function it might be okay as it is.
Thanks for your comments!
