Impact: Cleanup; fix inappropriate macro use ISA addresses on x86 are mapped 1:1 with the physical address space. Since the ISA address space is only 24 bits (32 for VLB or LPC) it will always fit in an unsigned int, and at least in the aha1542 driver using a wider type would cause an undesirable promotion. Hence explicitly cast the ISA bus addresses to unsigned int. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com> Cc: James Bottomley <James.Bottomley@hansenpartnership.com>

Impact: fix "garbled display, laptop is unusable" bug Commit e51a1ac2 ("x86, olpc: fix endian bug in openfirmware workaround") breaks model comparison on OLPC; the value 0xc2 needs to be scaled up by olpc_board(). The pre-patch version was wrong, but accidentally worked anyway (big-endian 0xc2 is big enough to satisfy all other board revisions, but little endian 0xc2 is not).

Commit 976e8f67 ("x86: asm/io.h: unify virt_to_phys/phys_to_virt") changed the return of virt_to_phys from long to phys_addr_t which is unsigned long long on a PAE platform. So, I could suggest a fix below since isa addresses may never be above 32 bits. Signed-off-by: Ingo Molnar <mingo@elte.hu>

uids in namespaces other than init don't get a sysfs entry. For those in the init namespace, while we're waiting to remove the sysfs entry for the uid the uid is still hashed, and alloc_uid() may re-grab that uid without getting a new reference to the user_ns, which we've already put in free_user before scheduling remove_user_sysfs_dir().

ASoC supports both explicit codec drivers for AC97 devices and a simple driver which uses the standard ALSA AC97 framework for codec support. When used with the generic AC97 codec support that will provide the ad hoc AC97 device for drivers like touchscreens to attach to so the core shouldn't do so.

Added the helper function snd_hda_multi_out_dig_cleanup() to clean up the digital outputs with multi setup. This call is needed in cases the codec supports multiple digital outputs as slaves. Otherwise the slave widgets aren't properly cleaned up. For a single digital output (e.g. in patch_conexant.c), this call isn't needed. Signed-off-by: Takashi Iwai <tiwai@suse.de>
