	---help---
	  This is a very small read-only file system mainly intended for
	  initial ram disks of installation disks, but it could be used for
	  other read-only media as well.  Read
	  <file:Documentation/filesystems/romfs.txt> for details.

	  To compile this file system support as a module, choose M here: the
	  module will be called romfs.  Note that the file system of your
	  root partition (the one containing the directory /) cannot be a
	  module.

	  If you don't know whether you need it, then you don't need it:
	  answer N.

config ROMFS_BACKED_BY_BLOCK
	bool "Block device-backed ROM file system support"
	depends on BLOCK
	help
	  This permits ROMFS to use block devices buffered through the page
	  cache as the medium from which to retrieve data.  It does not allow
	  direct mapping of the medium.

	  If unsure, answer Y.

config ROMFS_BACKED_BY_MTD
	bool "MTD-backed ROM file system support"
	depends on MTD=y || (ROMFS_FS=m && MTD)
	help
	  This permits ROMFS to use MTD based devices directly, without the
	  intercession of the block layer (which may have been disabled).  It
	  also allows direct mapping of MTD devices through romfs files under
	  NOMMU conditions if the underlying device is directly addressable by
	  the CPU.

	  If unsure, answer Y.

<div class='commit-subject'>x86/mce: Make timer handling more robust</div><div class='commit-msg'>Erik reported that on a preproduction hardware a CMCI storm triggers the
BUG_ON in add_timer_on(). The reason is that the per CPU MCE timer is
started by the CMCI logic before the MCE CPU hotplug callback starts the
timer with add_timer_on(). So the timer is already queued which triggers
the BUG.

Using add_timer_on() is pretty pointless in this code because the timer is
strictlty per CPU, initialized as pinned and all operations which arm the
timer happen on the CPU to which the timer belongs.

Simplify the whole machinery by using mod_timer() instead of add_timer_on()
which avoids the problem because mod_timer() can handle already queued
timers. Use __start_timer() everywhere so the earliest armed expiry time is
preserved.
