2011-01-10Blackfin: SMP: tweak platform_request_ipi() usageGraf Yang
This function takes an irq_handler_t function, but the prototype in the header doesn't match the function definition. This is due to the smp headers needing to avoid circular dependencies. So change the function to take a simple pointer. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: SMP: fix asm/bitops.h errorsMike Frysinger
The common asm-generic non-atomic bitops.h defines test_bit() for us, but we need to use our own version. So redirect the definition of this func to avoid having to inline the rest of the asm-generic file. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: SMP: fix cpumask misbehaviorGraf Yang
The cpu maps are defines provided by common linux/cpumask.h, not local variables. So stop exporting them locally and include the right header for their definition. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: SMP: rename the arch_xxx lock funcs to __raw_xxxGraf Yang
The external functions are named __raw_xxx, not arch_xxx, so rename the prototypes to match reality. This fixes some simple build errors in the bfin_ksyms.c code which exports these helpers to modules. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10serial: bfin_5xx: move resources into board filesSonic Zhang
Rather than maintain Kconfig entries where people have to enter raw numbers and hardcode lists of addresses/pins in the driver itself, push it all to platform resources. This lets us simplify the driver, the Kconfig, and gives board porters greater flexibility. In the process, we need to also start supporting the early platform interface. Not a big deal, but it causes the patch to be bigger than a simple resource relocation. All the Blackfin boards already have their resources updated and in place for this change.

2011-01-10Blackfin: drop asm/irq.h include from mach headersMike Frysinger
These were only included because of the irq handling of the PLL funcs, and those PLL funcs have been moved out into their own header now. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: bf51x/bf52x: drop redundant "base" def/cdef headerMike Frysinger
The defBF512.h header exists only to include defBF51x_base.h, and it is the only place where defBF51x_base.h is included. So move the contents of the defBF51x_base.h header into the defBF512.h header. Same situation for the other def/cdef pairs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: clean up mach header includesMike Frysinger
The main asm/blackfin.h header will pull in mach/blackfin.h to get all the fun Blackfin defines. So having any of the sub-mach headers trying to include asm/blackfin.h makes no sense -- punt it. The mach/blackfin.h header takes care of including the part-specific def headers which in turn will include any other needed def file. Similarly, it takes care of pulling in the part-specific cdef header. So move this logic out of the blackfin.h when necessary. Further, make sure the cdef headers do not waste time including the def headers again. Since all parts need the common def/cdef headers, move this logic out of the part-specific headers and into the mach/blackfin.h file. Finally, we need to split the BF539 def header since the BF538 does not have MXVR and we don't want to expose those MMRs. So now all parts should have the same behavior: mach/blackfin.h asm/def_LPBlackfin.h part-specific def.h if ! asm asm/cdef_LPBlackfin.h part-specific cdef.h And the sub def/cdef headers only tail into what they need. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: bf533: merge fio_flag back into normal mach headersMike Frysinger
We don't want the BF533 to be different in terms of its MMR headers, so merge the FIO_FLAG helpers back into the normal place. To avoid circular dependencies with headers, turn the inline C funcs into CPP defines. Not like there will be any code size differences. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: bf561-ezkit: add SMP defconfigMike Frysinger
Since the SMP code paths tend to compile fail a lot, start a SMP defconfig so our nightly build tools will automatically test it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10Blackfin: bf533: convert boards to gpio frameworkMike Frysinger
We don't want people banging on MMRs directly. As for the ip0x board, it shouldn't need to muck with the CS pin directly as the Blackfin SPI bus master driver takes care of driving this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-01-10Blackfin: standardize DMAC traffic control MMRs & MDMA MMRsMike Frysinger
Use the same naming convention for DMA traffic MMRs (most were legacy anyways) so we can avoid useless ifdef trees. Same goes for MDMA names -- this actually allows us to undo a bunch of ifdef redirects that existed for this purpose alone. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-01-10asm-generic/io.h: add reads[bwl]/writes[bwl] helpersMike Frysinger
A bunch of arches define reads[bwl]/writes[bwl] helpers for accessing memory mapped registers. Since the Blackfin ones aren't specific to Blackfin code, move them to the common asm-generic/io.h for people. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10net/irda: bfin_sir: back out transitional definesMike Frysinger

2011-01-10Blackfin: bfin_serial.h: unify heavily duplicated serial codeMike Frysinger
Each Blackfin port has been duplicating UART structures and defines when there really is no need for it. So start a new bfin_serial.h header to unify all these pieces and give ourselves a fresh start. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-01-10net/irda: bfin_sir: pull in serial headers for definesMike Frysinger
We're in the process of cleaning up the global Blackfin namespace, so the bfin_sir driver needs to pull in the serial header explicitly now. This does add a little transitional cruft to keep things compiling, but a follow up patch in this series will cull that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-01-10x86, lapic-timer: Increase the max_delta to 31 bitsPierre Tardy
Latest atom socs(penwell) does not have hpet timer. As their local APIC timer is clocked at 400KHZ, and the current code limit their Initial Counter register to 23 bits, they cannot sleep more than 1.34 seconds which leads to ~2 spurious wakeup per second (1 per thread) These SOCs support 32bit timer so we change the max_delta to at least 31bits. So we can at least sleep for 300 seconds. We could not find any previous chip errata where lapic would only have 23 bit precision As powertop is suggesting to activate HPET to "sleep longer", this could mean this problem is already known. Problem is here since very first implementation of lapic timer as a clock event e9e2cdb [PATCH] clockevents: i386 drivers.

2011-01-10nilfs2: unfold nilfs_dat_inode functionRyusuke Konishi
nilfs_dat_inode function was a wrapper to switch between normal dat inode and gcdat, a clone of the dat inode for garbage collection. This function got obsolete when the gcdat inode was removed, and now we can access the dat inode directly from a nilfs object. So, we will unfold the wrapper and remove it.

2011-01-10nilfs2: fiemap supportRyusuke Konishi
This adds fiemap to nilfs. Two new functions, nilfs_fiemap and nilfs_find_uncommitted_extent are added. nilfs_fiemap() implements the fiemap inode operation, and nilfs_find_uncommitted_extent() helps to get a range of data blocks whose physical location has not been determined. nilfs_fiemap() collects extent information by looping through nilfs_bmap_lookup_contig and nilfs_find_uncommitted_extent routines.

2011-01-10nilfs2: mark buffer heads as delayed until the data is written to diskRyusuke Konishi
Nilfs does not allocate new blocks on disk until they are actually written to. To implement fiemap, we need to deal with such blocks. To allow successive fiemap patch to distinguish mapped but unallocated regions, this marks buffer heads of those new blocks as delayed and clears the flag after the blocks are written to disk.

2011-01-10nilfs2: call nilfs_error inside bmap routinesRyusuke Konishi
Some functions using nilfs bmap routines can wrongly return invalid argument error (i.e. -EINVAL) that bmap returns as an internal code for btree corruption. This fixes the issue by catching and converting the internal EINVAL to EIO and calling nilfs_error function inside bmap routines. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

2011-01-10drm/radeon/kms: disable underscan by defaultAlex Deucher
Lots of HDMI TVs overscan the incoming image by default. The underscan option was added as a way to compensate for that by underscanning the image so that the edges would not be cut off on an overscanning TV. However, the TV provides no way of knowing whether it is overscanning or not. If the user has disabled overscan on their TV or has a TV that does not overscan, you will get black bars around the edges of your screen. Prior to the patch we got complaints and bug reports from users with overscanning TVs, now with the patch, we get lots of complaints and bug reports from users with non-overscanning TVs. There's no good default, but on average there have been more users complaining about it being on by default than off, so change it to off. This will probably result in a new deluge of overscanning TV user complaints. There's no winning. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-01-09cifs: move "ntlmssp" and "local_leases" options out of experimental codeJeff Layton
I see no real need to leave these sorts of options under an EXPERIMENTAL ifdef. Since you need a mount option to turn this code on, that only blows out the testing matrix. local_leases has been under the EXPERIMENTAL tag for some time, but it's only the mount option that's under this label. Move it out from under this tag. The NTLMSSP code is also under EXPERIMENTAL, but it needs a mount option to turn it on, and in the future any distro will reasonably want this enabled. Go ahead and move it out from under the EXPERIMENTAL tag.
