eager reclaim when possible Reclaiming pages is pointless when the cache can already satisfy all outstanding PoD entries, and doing reclaims in that case can be very harmful to performance when that memory gets used by the guest, but only to store zeroes there.

In fact, we should only sample NOW() from _inside_ the critical region within which the value we read is used. If we don't, in case we have to spin for a while before entering the region, when actually using it: 1) we will use something that, at the veryy least, is not really "now", because of the spinning, 2) if someone else sampled NOW() during a critical region protected by the lock we are spinning on, and if we compare the two samples when we get inside our region, our one will be 'earlier', even if we actually arrived later, which is a race. In Credit2, we see an instance of 2), in runq_tickle(), when it is called by csched2_context_saved() as it samples NOW() before acquiring the runq lock. This makes things look like the time went backwards, and it confuses the algorithm (there's even a d2printk() about it, which would trigger all the time, if enabled). In RTDS, something similar happens in repl_timer_handler(), and there's another instance in schedule() (in generic code), so fix these cases too. While there, improve csched2_vcpu_wake() and and rt_vcpu_wake() a little as well (removing a pointless initialization, and moving the sampling a bit closer to its use). These two hunks entail no further functional changes.

It is fine for AMD as NPT share the same format as normal pagetables. For Intel EPT however, it is wrong. The translation ends up correct (as the formats are sufficiently similar), but the control bits in lower 12 bits differ in meaning. A plain PT walker sets A/D bits (bits 5 and 6) as it walks, but in EPT tables, these are the IPAT and top bit of EMT (caching type). This in turn causes problem when the EPT tables are subsequently used. Replace hostmode->p2m_ga_to_gfn() with nestedhap_walk_L1_p2m() in paging_gva_to_gfn(), which is the correct function for the task. This involves making nestedhap_walk_L1_p2m() non-static, and adding vmx_vmcs_enter/exit() pairs to nvmx_hap_walk_L1_p2m() as it is now reachable from contexts other than v == current.

Such guests cannot be expected to be aware of those two features though (and so far we also don't expose the respective feature flags), and hence may suffer page faults they cannot deal with. While the placement of the re-enabling slightly weakens the intended protection, it was selected such that 64-bit paths would remain unaffected where possible. At the expense of a further performance hit the re-enabling could be put right next to the CLACs. Note that this introduces a number of extra TLB flushes - CR4.SMEP transitioning from 0 to 1 always causes a flush, and it transitioning from 1 to 0 may also do.
