X86_FEATURE_PKU is referred to as "PKU" in the hardware documentation: CPUID.7.0.ECX[3]:PKU. X86_FEATURE_OSPKE is software support for pkeys, enumerated with CPUID.7.0.ECX[4]:OSPKE, and it reflects the setting of CR4.PKE(bit 22).

2016-03-22KVM, pkeys: save/restore PKRU when guest/host switchesXiao Guangrong1-0/+23
Currently XSAVE state of host is not restored after VM-exit and PKRU is managed by XSAVE so the PKRU from guest is still controlling the memory access even if the CPU is running the code of host. This is not safe as KVM needs to access the memory of userspace (e,g QEMU) to do some emulation. So we save/restore PKRU when guest/host switches.

2016-03-22KVM: PPC: Create a virtual-mode only TCE table handlersAlexey Kardashevskiy3-7/+57
Upcoming in-kernel VFIO acceleration needs different handling in real and virtual modes which makes it hard to support both modes in the same handler. This creates a copy of kvmppc_rm_h_stuff_tce and kvmppc_rm_h_put_tce in addition to the existing kvmppc_rm_h_put_tce_indirect.

This patch fixes an active I/O shutdown bug for fabric drivers using target_wait_for_sess_cmds(), where se_cmd descriptor shutdown would result in hung tasks waiting indefinitely for se_cmd->cmd_wait_comp to complete(). To address this bug, drop the incorrect list_del_init() usage in target_wait_for_sess_cmds() and always complete() during se_cmd target_release_cmd_kref() put, in order to let caller invoke the final fabric release callback into se_cmd->se_tfo->release_cmd() code.

2016-03-21net: ipv4: Fix truncated timestamp returned by inet_current_timestamp()Deepa Dinamani1-1/+1
The millisecond timestamps returned by the function is converted to network byte order by making a call to htons(). htons() only returns __be16 while __be32 is required here. This was identified by the sparse warning from the buildbot: net/ipv4/af_inet.c:1405:16: sparse: incorrect type in return expression (different base types) net/ipv4/af_inet.c:1405:16: expected restricted __be32 net/ipv4/af_inet.c:1405:16: got restricted __be16 [usertype] <noident> Change the function to use htonl() to return the correct __be32 type instead so that the millisecond value doesn't get truncated.

2016-03-21Make DST_CACHE a silent config optionDave Jones1-1/+1
commit 911362c70d ("net: add dst_cache support") added a new kconfig option that gets selected by other networking options. It seems the intent wasn't to offer this as a user-selectable option given the lack of help text, so this patch converts it to a silent option.
