The big ugly one. This patch adds support for switching in and out of
system management mode, respectively upon receiving KVM_REQ_SMI and upon
executing a RSM instruction. Both 32- and 64-bit formats are supported
for the SMM state save area.

Commit 066450be41 ("perf/x86/intel/pt: Clean up the control flow
in pt_pmu_hw_init()") changed attribute initialization so that
only the first attribute gets initialized using
sysfs_attr_init(), which upsets lockdep.
This patch fixes the glitch so that all allocated attributes are
properly initialized thus fixing the lockdep warning reported by
Tvrtko and Imre.

Do not process INITs immediately while in system management mode, keep
it instead in apic->pending_events. Tell userspace if an INIT is
pending when they issue GET_VCPU_EVENTS, and similarly handle the
new field in SET_VCPU_EVENTS.
Note that the same treatment should be done while in VMX non-root mode.

SMBASE is only readable from SMM for the VCPU, but it must be always
accessible if userspace is accessing it. Thus, all functions that
read MSRs are changed to accept a struct msr_data; the host_initiated

on return.

The AF_IEEE802154 sockaddr looks like this:
struct sockaddr_ieee802154 {
sa_family_t family; /* AF_IEEE802154 */
struct ieee802154_addr_sa addr;
};
struct ieee802154_addr_sa {
int addr_type;
u16 pan_id;
union {
u8 hwaddr[IEEE802154_ADDR_LEN];
u16 short_addr;
};
};
On most architectures there will be implicit structure padding here,
in two different places:
* In struct sockaddr_ieee802154, two bytes of padding between 'family'
(unsigned short) and 'addr', so that 'addr' starts on a four byte
boundary.
* In struct ieee802154_addr_sa, two bytes at the end of the structure,
to make the structure 16 bytes.
When calling recvmsg(2) on a PF_IEEE802154 SOCK_DGRAM socket, the
ieee802154 stack constructs a struct sockaddr_ieee802154 on the
kernel stack without clearing these padding fields, and, depending
on the addr_type, between four and ten bytes of uncleared kernel
stack will be copied to userspace.
We can't just insert two 'u16 __pad's in the right places and zero
those before copying an address to userspace, as not all architectures
insert this implicit padding -- from a quick test it seems that avr32,
cris and m68k don't insert this padding, while every other architecture
that I have cross compilers for does insert this padding.
The easiest way to plug the leak is to just memset the whole struct
sockaddr_ieee802154 before filling in the fields we want to fill in,
and that's what this patch does.

The topology core parses the FW topology file for known block types and
instanciates any common ALSA/ASoC objects that it discovers. The core
also passes any block that is does not understand to client component
drivers for enumeration.
The core exports some APIs to client drivers in order to load and unload
firmware topology data as use case require.
Currently the core deals with the following object types :-
o kcontrols. This includes TLV, enumerated and bytes controls.
o DAPM widgets. All types with any associated kcontrol.
o DAPM graph.
o FE PCM. FE PCM capabilities and configuration can be defined.
o BE DAI Link. BE DAI link capabilities and configuration can be defined.

tcp_v4_rcv() checks the following before calling tcp_v4_do_rcv():
if (th->doff < sizeof(struct tcphdr) / 4)
goto bad_packet;
if (!pskb_may_pull(skb, th->doff * 4))
goto discard_it;
So following check in tcp_v4_do_rcv() is redundant
and "goto csum_err;" is wrong anyway.
if (skb->len < tcp_hdrlen(skb) || ...)
goto csum_err;
A second check can be removed after no_tcp_socket label for same reason.
Same tests can be removed in tcp_v6_do_rcv()
Note : short tcp frames are not properly accounted in tcpInErrs MIB,
because pskb_may_pull() failure simply drops incoming skb, we might
fix this in a separate patch.

MMC_PM_KEEP_POWER doesn't imply MMC_PM_WAKE_SDIO_IRQ, we should only
enable device wake up when MMC_PM_WAKE_SDIO_IRQ is set. And "pm_flags"

need to disable device wakeup explicitly.
