When acpi_extlog was added, we were worried that the same error would be reported more than once by different subsystems. But in the ensuing years I've seen complaints that people could not find an error log (because this mechanism suppressed the log they were looking for). Rip it all out. People are smart enough to notice the same address from different reporting mechanisms. Signed-off-by:

Instead of keeping count of how many handlers are registered on the MCE notifier chain and printing if below some magic value, look at mce->kflags to see if anyone claims to have handled/logged this error. [ bp: Do not print ->kflags in __print_mce(). ] Signed-off-by:

If the handler took any action to log or deal with the error, set a bit in mce->kflags so that the default handler on the end of the machine check chain can see what has been done. Get rid of NOTIFY_STOP returns. Make the EDAC and dev-mcelog handlers skip over errors already processed by CEC. Signed-off-by:

There can be many different subsystems register on the mce handler chain. Add a new bitmask field and define values so that handlers can indicate whether they took any action to log or otherwise handle an error. The default handler at the end of the chain can use this information to decide whether to print to the console log. Boris suggested a generic name and leaving plenty of spare bits for possible future use. [ bp: Move flag bits to the internal mce.h header and use BIT_ULL(). ] Signed-off-by:

This sorts the actual field names too, potentially causing even more chaos and confusion at merge time if you have edited the MAINTAINERS file. But the end result is a more consistent layout, and hopefully it's a one-time pain minimized by doing this just before the -rc1 release.

They are all supposed to be sorted, but people who add new entries don't always know the alphabet. Plus sometimes the entry names get edited, and people don't then re-order the entry. Let's see how painful this will be for merging purposes (the MAINTAINERS file is often edited in various different trees), but Joe claims there's relatively few patches in -next that touch this, and doing it just before -rc1 is likely the best time. Fingers crossed. This was scripted with /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS but then I also ended up manually upper-casing a few entry names that stood out when looking at the end result.

Two types of #AC can be generated in Intel CPUs: 1. legacy alignment check #AC 2. split lock #AC Reflect #AC back into the guest if the guest has legacy alignment checks enabled or if split lock detection is disabled. If the #AC is not a legacy one and split lock detection is enabled, then invoke handle_guest_split_lock() which will either warn and disable split lock detection for this task or force SIGBUS on it.

Emulate split-lock accesses as writes if split lock detection is on to avoid #AC during emulation, which will result in a panic(). This should never occur for a well-behaved guest, but a malicious guest can manipulate the TLB to trigger emulation of a locked instruction[1]. More discussion can be found at [2][3].

Without at least minimal handling for split lock detection induced #AC, VMX will just run into the same problem as the VMWare hypervisor, which was reported by Kenneth. It will inject the #AC blindly into the guest whether the guest is prepared or not. Provide a function for guest mode which acts depending on the host SLD mode. If mode == sld_warn, treat it like user space, i.e. emit a warning, disable SLD and mark the task accordingly. Otherwise force SIGBUS.
