This patch causes all the EFI_RESERVED_TYPE memory reservations to be recorded in the e820 table as type E820_RESERVED. (This patch replaces one called 'x86: vendor reserved memory type'. This version has been discussed a bit with Peter and Yinghai but not given a final opinion.) Without this patch EFI_RESERVED_TYPE memory reservations may be marked usable in the e820 table. There may be a collision between kernel use and some reserver's use of this memory. (An example use of this functionality is the UV system, which will access extremely large areas of memory with a memory engine that allows a user to address beyond the processor's range. Such areas are reserved in the EFI table by the BIOS. Some loaders have a restricted number of entries possible in the e820 table, hence the need to record the reservations in the unrestricted EFI table.) The call to do_add_efi_memmap() is only made if "add_efi_memmap" is specified on the kernel command line. Signed-off-by: NCliff Wickman <cpw@sgi.com> Signed-off-by: NH. Peter Anvin <hpa@zytor.com>

iomem_resource is by default initialized to -1, which means 64 bits of physical address space if 64-bit resources are enabled. However, x86 CPUs cannot address 64 bits of physical address space. Thus, we want to cap the physical address space to what the union of all CPU can actually address. Without this patch, we may end up assigning inaccessible values to uninitialized 64-bit PCI memory resources. Signed-off-by: NH.

If one CPU has no_way_out == 1, all other CPUs should have no_way_out == 1. But despite global_nwo is read after mce_callin, global_nwo is updated after mce_callin too. So it is possible that some CPU read global_nwo before some other CPU update global_nwo, so that no_way_out == 1 for some CPU, while no_way_out == 0 for some other CPU. This patch fixes this race condition via moving mce_callin updating after global_nwo updating, with a smp_wmb in between. A smp_rmb is added between their reading too.

由 Haavard Skinnemoen 提交于
After enabling hardware flow control, any subsequent termios call may hang waiting for the transmitter to drain. This appears to be caused by a busy-loop in set_termios() waiting for the transmitter to become empty, which may take a very long time (or hang indefinitely) if the device at the other end is blocking us. A quick look through the tty and serial_core code indicates that any necessary flushing (which is optional) has already been done at this point, so there's no need for the driver to flush the transmitter on its own. Fix it by removing the busy-loop altogether.
