* ARM: S3C24XX: Add extended GPIO used on S3C2443 and beyondBen Dooks2010-05-064-5/+69
| | | | | | | | | | | Add the GPIO banks that are used on the S3C2443 and above to the list of available GPIOS. Currently we do not have any limit on the SoC GPIO, so these are being registered whether the SoC has them or not. It is currently up to the user not to try and use them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the original code we used "j" as an iterator but we used "i" as an index. - for (j = 0; j < i; j++) - device_remove_file(&connector->kdev, - &connector_attrs[i]); Smatch complained about that because "i" was potentially passed the end of the array. Which makes sense if we should be using "j" there. I also thought that we should remove the files for &connector_attrs_opt1 but to do that I had to add separate iterators for &connector_attrs and &connector_attrs_opt1.

| | | | | | | | | | | | | | | | | | | | | | | | Selecting the wrong or no CONFIG_AGP_* chipset can cause a NULL pointer dereference when combined with CONFIG_DRM_RADEON_KMS and an old system with a R100 AGP card (should effect other cards too). The agp field will be set to NULL if no suitable AGP chipset driver is loaded, drm_agp_acquire already preforms a suitable NULL check so it can be used directly.

The root cause of boot failure problem is the value of 'slot_virt[i]' was initialized in setup_arch->early_ioremap_init(). But later in setup_arch, the function 'parse_early_param' will modify 'FIXADDR_TOP' when 'reservetop=0xbadc0de' being specified. The simplest fix might be use __fix_to_virt(idx0) to get updated value of 'FIXADDR_TOP' in '__early_ioremap' instead of reference old value from slot_virt[slot] directly. Changelog since v0: -v1: When reservetop being handled then FIXADDR_TOP get adjusted, Hence check prev_map then re-initialize slot_virt and PMD based on new FIXADDR_TOP. -v2: place fixup_early_ioremap hence call early_ioremap_init in reserve_top_address to re-initialize slot_virt and corresponding PMD when parse_reservertop -v3: move fixup_early_ioremap out of reserve_top_address to make sure other clients of reserve_top_address like xen/lguest won't broken Signed-off-by: Liang Li <liang.li@windriver.com> Tested-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Acked-by: Yinghai Lu <yinghai@kernel.org> Acked-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Cc: Wang Chen <wangchen@cn.fujitsu.com> Cc: "H.

Given that it only needs to read the key list, and it's doing so under a spinlock, the RCU read lock is the thing to use. Furthermore, the RCU check added in e7b0a61b7929632d36cf052d9e2820ef0a9c1bfe is incorrect as holding the spinlock on key_serial_lock is not grounds for assuming a keyring's pointer list can be read safely. Instead, a simple rcu_dereference() inside of the previously mentioned RCU read lock is what we want. Reported-by: Serge E.

Instead, we add a flag, OCFS2_INODE_SKIP_ORPHAN_DIR which tells the inode wipe code that it won't find this inode in the orphan dir.

Use a regular byte read instead for the address they live at (0x73). These are the only known chips living at this address on PC systems. For clarity, this fix should not be needed for kernels 2.6.30 and later, as we started instantiating the hwmon devices explicitly based on DMI data. Still, this fix is valuable in the following two cases: * Support for recent FSC chips on older kernels. The DMI-based device instantiation is more difficult to backport than the device support itself. * Case where the DMI-based device instantiation fails, whatever the reason. We fall back to probing in that case, so it should work.

It is assumed that the core may access the private data after remove() as there are no guarantees for the lifetime of such pointers anyhow (see thread starting at http://lkml.org/lkml/2010/3/21/68) Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>
