      fix a kmap leak in virtio_console · c9efe511
      由 Al Viro 提交于 
      While we are at it, don't do kmap() under kmap_atomic(), *especially*
for a page we'd allocated with GFP_KERNEL.  It's spelled "page_address",
and had that been more than that, we'd have a real trouble - kmap_high()
can block, and doing that while holding kmap_atomic() is a Bad Idea(tm).

      watchdog: dw_wdt: Add dependency on HAS_IOMEM · 1ccfe6f9
      由 Richard Weinberger 提交于 
      On archs like S390 or um this driver cannot build nor work.
Make it depend on HAS_IOMEM to bypass build failures.

drivers/built-in.o: In function `dw_wdt_drv_probe':
drivers/watchdog/dw_wdt.c:302: undefined reference to `devm_ioremap_resource'

      tty: Set correct tty name in 'active' sysfs attribute · d8a5dc30
      由 Hannes Reinecke 提交于 
      The 'active' sysfs attribute should refer to the currently active tty
devices the console is running on, not the currently active console.

The console structure doesn't refer to any device in sysfs, only the tty
the console is running on has.  So we need to print out the tty names in
'active', not the console names.

This resolves an issue on s390 platforms in determining the correct
console device to use.

      tty: n_gsm: Fix for modems with brk in modem status control · 3ac06b90
      由 Lars Poeschel 提交于 
      3GPP TS 07.10 states in section 5.4.6.3.7:
"The length byte contains the value 2 or 3 ... depending on the break
signal." The break byte is optional and if it is sent, the length is
3. In fact the driver was not able to work with modems that send this
break byte in their modem status control message. If the modem just
sends the break byte if it is really set, then weird things might
happen.
The code for deconding the modem status to the internal linux
presentation in gsm_process_modem has already a big comment about
this 2 or 3 byte length thing and it is already able to decode the
brk, but the code calling the gsm_process_modem function in
gsm_control_modem does not encode it and hand it over the right way.
This patch fixes this.
Without this fix if the modem sends the brk byte in it's modem status
control message the driver will hang when opening a muxed channel.

      drivers/tty/hvc: don't use module_init in non-modular hyp. console code · 4fedd0bf
      由 Paul Gortmaker 提交于 
      The HVC_OPAL/RTAS/UDBG/XEN options are all bool, and hence their support
is either present or absent.  It will never be modular, so using
module_init as an alias for __initcall is rather misleading.

Fix this up now, so that we can relocate module_init from
init.h into module.h in the future.  If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.

Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups.  As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.

Also the __exitcall functions have been outright deleted since
they are only ever of interest to UML, and UML will never be
using any of this code.
