* | | | | | vm: convert HPET mmap to vm_iomap_memory() helperLinus Torvalds2013-04-191-13/+1
| |_|/ / / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is my example conversion of a few existing mmap users. The HPET case is simple, widely available, and easy to test (Clemens Ladisch sent a trivial test-program for it).

A simple recipe to cause badness is: * create a QEMU VM with two virtio-serial ports * in the guest, do while true;do echo abc >/dev/vport0p1;done while true;do echo edf >/dev/vport0p2;done In one run, this caused a panic in __send_control_msg(). In another, I got virtio_console virtio0: control-o:id 0 is not a head! This also results repeated messages similar to these on the host: qemu-kvm: virtio-serial-bus: Unexpected port id 478762112 for device virtio-serial-bus.0 qemu-kvm: virtio-serial-bus: Unexpected port id 478762368 for device virtio-serial-bus.0 Reported-by: FuXiangChun <xfu@redhat.com> Signed-off-by: Amit Shah <amit.shah@redhat.com> Reviewed-by: Wanlong Gao <gaowanlong@cn.fujitsu.com> Reviewed-by: Asias He <asias@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: stable@kernel.org

There's no reason why kill_fasync() needs to be taken while the random pool is locked, so move it out to fix this locking dependency.

| |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | virtio_rng feeds the randomness buffer handed by the core directly into the scatterlist, since commit bb347d98079a547e80bd4722dee1de61e4dca0e8. However, if CONFIG_HW_RANDOM=m, the static buffer isn't a linear address (at least on most archs). We could fix this in virtio_rng, but it's actually far easier to just do it in the core as virtio_rng would have to allocate a buffer every time (it doesn't know how much the core will want to read).

This capability is important for fault-tolerant systems. Even if the kernel option ipmi_si.trydefaults=0 is specified, ipmi_si discovers and claims one of the KCS interfaces on a Stratus server. The inability to now prevent the kernel from managing this device is a regression from previous kernels. The regression breaks a capability fault-tolerant vendors have relied upon. To support both ACPI opregion access and the need to avoid activation of ipmi_si on some platforms, we've added two new kernel options, ipmi_si.tryacpi and ipmi_si.trydmi be added to prevent ipmi_si from initializing when these options are set to 0 on the kernel command line. With these options at the default value of 1, ipmi_si init proceeds according to the kernel default.

Aside from simpler code, removing another member for the intel_gtt struct is a nice motivation.

There is some slight functionality changes. There was extra paranoid checks in AGP code making sure we never do idle maps on gen2 parts. That was not duplicated as the simple PCI id check should do the right thing. v2: use IS_GEN5 && IS_MOBILE check instead. For now, this is the same as IS_IRONLAKE_M but is more future proof. The workaround docs hint that more than one platform may be effected, but we've never seen such a platform in the wild.

We want to clear two flags here. #define SerialSignal_RTS 0x20 /* Request to Send */ #define SerialSignal_DTR 0x80 /* Data Terminal Ready */ Without the parenthesis then it does: info->serial_signals &= 0x5f; With the parenthesis it does: info->serial_signals &= 0xffffff5f; info->serial_signals is an unsigned char so the two statements are equivalent, but it's cleaner to add the parenthesis. In other dtr_rts() functions the parenthesis are there so this makes it more consistent. Other changes: Convert all + uses to | for these bit operations. Reorder the multiple fields for consistency.

This saves space on systems that won't support TTY interfaces anyway. bloat-o-meter output is below. The bulk of this patch consists of Kconfig changes adding "depends on TTY" to various serial devices and similar drivers that require the TTY layer. Ideally, these dependencies would occur on a common intermediate symbol such as SERIO, but most drivers "select SERIO" rather than "depends on SERIO", and "select" does not respect dependencies. bloat-o-meter output comparing our previous minimal to new minimal by removing TTY.
