It works in so called "Firmware First" mode, that is, hardware errors are reported to firmware firstly, then reported to Linux by firmware. This way, some non-standard hardware error registers or non-standard hardware link can be checked by firmware to produce more valuable hardware error information for Linux. Now, only SCI notification type and memory errors are supported. More notification type and hardware error type will be added later. These memory errors are reported to user space through /dev/mcelog via faking a corrected Machine Check, so that the error memory page can be offlined by /sbin/mcelog if the error count for one page is beyond the threshold. On some machines, Machine Check can not report physical address for some corrected memory errors, but GHES can do that. So this simplified GHES is implemented firstly.

This patch provides a unified definition for UUID/GUID. UUID is defined via typedef. This makes that UUID appears more like a preliminary type, and makes the data type explicit (comparing with implicit "u8 uuid[16]"). The binary representation of UUID/GUID can be little-endian (used by EFI, etc) or big-endian (defined by RFC4122), so both is defined.

It also allows the platform to report error sources for which OS would typically not implement support (for example, chipset-specific error registers). HEST information may be needed by other subsystems. For example, HEST PCIE AER error source information describes whether a PCIE root port works in "firmware first" mode, this is needed by general PCIE AER error subsystem. So a public HEST tabling parsing interface is provided. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

This improves NMI handling especially. In addition it supports error serialization and error injection. For more information about APEI, please refer to ACPI Specification version 4.0, chapter 17. This patch provides some common functions used by more than one APEI tables, mainly framework of interpreter for EINJ and ERST. A machine readable language is defined for EINJ and ERST for OS to execute, and so to drive the firmware to fulfill the corresponding functions. The machine language for EINJ and ERST is compatible, so a common framework is defined for them.

For example, APEI ERST operations may be used for permanent storage in hardware error handler. That is, it may be called in atomic contexts such as IRQ or NMI, etc. And, ERST/EINJ implement their operations via IO memory/port accessing. But the IO memory accessing method provided by ACPI (acpi_read/acpi_write) maps the IO memory during it is accessed, so it can not be used in atomic context. To solve the issue, the IO memory should be pre-mapped during EINJ/ERST initializing. A linked list is used to record which memory area has been mapped, when memory is accessed in hardware error handler, search the linked list for the mapped virtual address from the given physical address.

This patch fixes this. Note that I discovered that our existing GSO MTU checks (e.g., IPv4 forwarding) are buggy in that they skip the check altogether, when they really should be checking gso_size + header instead. I have also been lazy here in that I haven't bothered to segment the GSO packet by hand before generating an ICMP message. Someone should add that to be 100% correct.

But it is unsafe to protect two threads, one using regular lock_sock/release_sock, one using lock_sock_bh/unlock_sock_bh This patch changes lock_sock_bh to be careful against 'owned' state. If owned is found to be set, we must take the slow path. lock_sock_bh() now returns a boolean to say if the slow path was taken, and this boolean is used at unlock_sock_bh time to call the appropriate unlock function. After this change, BH are either disabled or enabled during the lock_sock_bh/unlock_sock_bh protected section. This might be misleading, so we rename these functions to lock_sock_fast()/unlock_sock_fast().
