Many msrs and the like will only be used by the host if we schedule() or return to userspace. Therefore, we avoid saving them if we handle the exit within the kernel, and if a reschedule is not requested. Based on a patch from Eddie Dong <eddie.dong@intel.com> with a couple of fixes by me.

This allows us to remove write protection earlier than otherwise. Should some mad OS choose to use byte writes to update pagetables, it will suffer a performance hit, but still work correctly. Signed-off-by: -

He, Qing authored
This patch enables IO bitmaps control on vmx and unmask the 0x80 port to avoid VMEXITs caused by accessing port 0x80. 0x80 is used as delays (see include/asm/io.h), and handling VMEXITs on its access is unnecessary but slows things down. This patch improves kernel build test at around 3%~5%. Because every VM uses the same io bitmap, it is shared between all VMs rather than a per-VM data structure. Signed-off-by:

It depends on tristate I2C and it's trivial to make modular. The current Kconfig allows I2C=m, I2C_ACORN=y, which doesn't work at all; alternatives are dependency on I2C=y and making I2C_ACORN itself a tristate. The latter is the right thing to do... Signed-off-by:

Clean up pda_power interrupt handling: Prior to this patch, the driver would pass information it needed to the interrupt handler dev_id pointer, and then prompt forget it ever did so, recreating that same information after a couple passes through the timer-based state machine. This patch removes the redundant checks by passing the pda_power_supply[] pointer through the state machine. The current code passed 'irq' through the state machine, as an index to recreate the pointer, when we could more simply pass around the pointer itself. This patch makes it easier to remove the 'irq' argument in the future, in addition to cleaning up the driver today. Signed-off-by: -

The NET_CLS_ACT option is now a full replacement for NET_CLS_POLICE, remove the old code. The config option will be kept around to select the equivalent NET_CLS_ACT options for a short time to allow easier upgrades. Signed-off-by:

Patrick McHardy authored
The behaviour of NET_CLS_POLICE for TC_POLICE_RECLASSIFY was to return it to the qdisc, which could handle it internally or ignore it. With NET_CLS_ACT however, tc_classify starts over at the first classifier and never returns it to the qdisc. This makes it impossible to support qdisc-internal reclassification, which in turn makes it impossible to remove the old NET_CLS_POLICE code without breaking compatibility since we have two qdiscs (CBQ and ATM) that support this. This patch adds a tc_classify_compat function that handles reclassification the old way and changes CBQ and ATM to use it. This again is of course not fully backwards compatible with the previous NET_CLS_ACT behaviour. Unfortunately there is no way to fully maintain compatibility *and* support qdisc internal reclassification with NET_CLS_ACT, but this seems like the better choice over keeping the two incompatible options around forever.
