Kay Sievers bc65c724d5 mmc: fix platform driver hotplug/coldplug
Since 43cc71eed1, the platform modalias is
prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable MMC host
platform drivers, to re-enable auto loading.

Also, add missing owner declarations in driver init.

Ingo Molnar bead9a3abd mm: sparsemem memory_present() fix
Fix memory corruption and crash on 32-bit x86 systems.

If a !PAE x86 kernel is booted on a 32-bit system with more than 4GB of
RAM, then we call memory_present() with a start/end that goes outside
the scope of MAX_PHYSMEM_BITS.

That causes this loop to happily walk over the limit of the sparse
memory section map:

    for (pfn = start; pfn < end; pfn += PAGES_PER_SECTION) {
                unsigned long section = pfn_to_section_nr(pfn);
                struct mem_section *ms;

                sparse_index_init(section, nid);
                set_section_nid(section, nid);

                ms = __nr_to_section(section);
                if (!ms->section_mem_map)
                        ms->section_mem_map = sparse_encode_early_nid(nid) |
			                                SECTION_MARKED_PRESENT;

'ms' will be out of bounds and we'll corrupt a small amount of memory by
encoding the node ID and writing SECTION_MARKED_PRESENT (==0x1) over it.

The corruption might happen when encoding a non-zero node ID, or due to
the SECTION_MARKED_PRESENT which is 0x1:

	mmzone.h:#define	SECTION_MARKED_PRESENT	(1UL<<0)

The fix is to sanity check anything the architecture passes to
sparsemem.

This bug seems to be rather old (as old as sparsemem support itself),
but the exact incarnation depended on random details like configs, which
made this bug more prominent in v2.6.25-to-be.

An additional enhancement might be to print a warning about ignored or
trimmed memory ranges.

Linus Torvalds 093a07e2fd Fix locking bug in "acquire_console_semaphore_for_printk()"
When I cleaned up printk() and split up the printk locking logic in
commit 266c2e0abe ("Make printk() console
semaphore accesses sensible") I had incorrectly moved the call to
have_callable_console() outside of the console semaphore.

That was buggy.  The console semaphore protects the console_drivers list
that is used by have_callable_console().

Thanks go to Bongani Hlope who saw this as a hang on shutdown and reboot
and bisected the bug to the right commit, and tested this patch. See

Johannes Berg b3fc9c6c58 mac80211: remove message on receiving unexpected unencrypted frames
Some people are getting this message a lot, and we have traced it to
broken access points that much too often send completely empty frames
(all bytes zeroed, which they shouldn't do at all.)

Since we cannot do anything about such frames in any case except the
special case where we're debugging an AP, just remove the message.

Carlos Corbacho 89796f64a2 rfkill: Fix device type check when toggling states
rfkill_switch_all() is supposed to only switch all the interfaces of a
given type, but does not actually do this; instead, it just switches
everything currently in the same state.

Add the necessary type check in.

(This fixes a bug I've been seeing while developing an rfkill laptop
driver, with both bluetooth and wireless simultaneously changing state
after only pressing either KEY_WLAN or KEY_BLUETOOTH).

Michael Buesch 4ac58469f1 ssb: Fix usage of struct device used for DMAing
This fixes DMA on architectures where DMA is nontrivial, like PPC64.
We must use the host-device's (PCI) struct device for any DMA
operation instead of the SSB device. For this we add a new
struct device pointer to the SSB device structure that will always
point to the right device for DMAing.

Without this patch b43 and b44 drivers won't work on complex-DMA
architectures, that for example need dev->archdata for DMA operations.

Michael Ellerman 0517deed78 netconsole: only set CON_PRINTBUFFER if the user specifies a netconsole
Since 0bcc181618 (netconsole: Support
dynamic reconfiguration using configfs), the netconsole is always
registered, regardless of whether the user actually specified a
netconsole configuration on the command line.

However because netconsole has CON_PRINTBUFFER set, when it is
registered it causes the printk buffer to be replayed to all consoles.
When there is no netconsole configured this is a) pointless, and b)
somewhat annoying for the user of the existing console.

So instead we should only set CON_PRINTBUFFER if there is a netconsole
configuration found on the command line. This retains the existing
behaviour if a netconsole is setup by the user, and avoids spamming
other consoles when we're only registering for the dynamic
netconsole case.
