2011-03-14clean statfs-like syscalls upAl Viro
New helpers: user_statfs() and fd_statfs(), taking userland pathname and descriptor resp. and filling struct kstatfs. Syscalls of statfs family (native, compat and foreign - osf and hpux on alpha and parisc resp.) switched to those. Removes some boilerplate code, simplifies cleanup on errors...

2011-03-14open-style analog of vfs_path_lookup()Al Viro
new function: file_open_root(dentry, mnt, name, flags) opens the file vfs_path_lookup would arrive to. Note that name can be empty; in that case the usual requirement that dentry should be a directory is lifted. open-coded equivalents switched to it, may_open() got down exactly one caller and became static. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-03-14kill path_lookup()Al Viro
all remaining callers pass LOOKUP_PARENT to it, so flags argument can die; renamed to kern_path_parent() Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2011-03-10powerpc/pseries: Disable VPNH featureBenjamin Herrenschmidt
This feature triggers nasty races in the scheduler between the rebuilding of the topology and the load balancing code, causing the machine to hang. Disable it for now until the races are fixed. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2011-03-10powerpc/iseries: Fix early init access to lppacaBenjamin Herrenschmidt
The combination of commit 8154c5d22d91cd16bd9985b0638c8957e4688d0e and 93c22703efa72c7527dbd586d1951c1f4a85fd70 Broke boot on iSeries. The problem is that iSeries very early boot code, which generates the device-tree and runs before our normal early initializations does need access the lppaca's very early, before the PACA array is initialized, and in fact even before the boot PACA has been initialized (it contains all 0's at this stage). However, the first patch above makes that code use the new llpaca_of(cpu) accessor, which itself is changed by the second patch to use the PACA array. We fix that by reverting iSeries to directly dereferencing the array. In addition, we fix all iterators in the iSeries code to always skip CPU whose number is above 63 which is the maximum size of that array and the maximum number of supported CPUs on these machines. Additionally, we make sure the boot_paca is properly initialized in our early startup code. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2011-03-09[CPUFREQ] pcc-cpufreq: don't load driver if get_freq fails during init.Naga Chumbalkar
Return 0 on failure. This will cause the initialization of the driver to fail and prevent the driver from loading if the BIOS cannot handle the PCC interface command to "get frequency". Otherwise, the driver will load and display a very high value like "4294967274" (which is actually -EINVAL) for frequency: # cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 4294967274 Signed-off-by: Naga Chumbalkar <nagananda.chumbalkar@hp.com> CC: stable@kernel.org Signed-off-by: Dave Jones <davej@redhat.com>
2011-03-09x86, UV: Initialize the broadcast assist unit base destination node id properlyCliff Wickman

Reduce the logging output of s3c64xx_dma_init1() as it is not useful for normal bootup (and we get an overall indication of the registration of the PL180 DMA block). This removes the following output from the log: s3c64xx_dma_init1: registering DMA 0 (e0808100) s3c64xx_dma_init1: registering DMA 1 (e0808120) s3c64xx_dma_init1: registering DMA 2 (e0808140) s3c64xx_dma_init1: registering DMA 3 (e0808160) s3c64xx_dma_init1: registering DMA 4 (e0808180) s3c64xx_dma_init1: registering DMA 5 (e08081a0) s3c64xx_dma_init1: registering DMA 6 (e08081c0) s3c64xx_dma_init1: registering DMA 7 (e08081e0) Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2011-03-04ARM: S3C64XX: Fix keypad setup to configure correct number of rowsBen Dooks
The call to s3c_gpio_cfgrange_nopull() takes a size and base but this looks like it is trying to do base and end. This means it is configuring too many GPIOs and on the case of the Cragganmore means we're seeing an overflow of the ROW pins causing problems with the keyboard driver.

2011-03-04ARM: S3C2440: Fix usage gpio bank j pin definitions on GTA02Lars-Peter Clausen
The gta02 header file still uses the old S3C2410_GPJx defines instead of the S3C2410_GPJ(x) macro. Since the S3C2410_GPJx defines have already been removed this causes the following build failure: sound/soc/samsung/neo1973_wm8753.c: In function 'lm4853_set_spk': sound/soc/samsung/neo1973_wm8753.c:259: error: 'S3C2440_GPJ2' undeclared (first use in this function) sound/soc/samsung/neo1973_wm8753.c:259: error: (Each undeclared identifier is reported only once sound/soc/samsung/neo1973_wm8753.c:259: error: for each function it appears in.) sound/soc/samsung/neo1973_wm8753.c: In function 'lm4853_get_spk': sound/soc/samsung/neo1973_wm8753.c:267: error: 'S3C2440_GPJ2' undeclared (first use in this function) sound/soc/samsung/neo1973_wm8753.c: In function 'lm4853_event': sound/soc/samsung/neo1973_wm8753.c:276: error: 'S3C2440_GPJ1' undeclared (first use in this function) sound/soc/samsung/neo1973_wm8753.c: At top level: sound/soc/samsung/neo1973_wm8753.c:439: error: 'S3C2440_GPJ2' undeclared here (not in a function) sound/soc/samsung/neo1973_wm8753.c:440: error: 'S3C2440_GPJ1' undeclared here (not in a function) This patches fixes the issue by doing a s,S3C2410_GPJ([\d]+),S3C2410_GPJ(\1),g on the file.

This patch modifies the number of total GPIO lines for Bank F for Samsung S5P6440 and S5P6450 SoCs from 2 to 16. This is necessary as the GPIO lines from 0 to 13 are reserved and only lines 14 and 15 are used. As during initialization, the line number starts at 0, putting 2 does not solve the intended purpose.
