perf: Generic perf_sample_data initialization

[PATCH] pid_ns: zap_pid_ns_processes: use SEND_SIG_NOINFO instead of force_sig()
zap_pid_ns_processes() uses force_sig(SIGKILL) to ensure SIGKILL will be delivered to sub-namespace inits as well. This is correct, but we are going to change force_sig_info() semantics. See http://bugzilla.kernel.org/show_bug.cgi?id=15395#c31 We can use send_sig_info(SEND_SIG_NOINFO) instead, since 614c517d7c00... 3 Mar 2010 16:25

[PATCH] cxgb3: fix hot plug removal crash

[PATCH 01/18] KVM: MMU: Check for root_level instead of long mode
The walk_addr function checks for !is_long_mode in its 64 bit version. But what is meant here is a check for pae paging. Change the condition to really check for pae paging so that it also works with nested nested paging.

[PATCH 02/18] KVM: MMU: Make tdp_enabled a mmu-context parameter
This patch changes the tdp_enabled flag from its global meaning to the mmu-context. This is necessary for Nested SVM with emulation of Nested Paging where we need an extra MMU context to shadow the Nested Nested Page Table.
