* f2fs: rename f2fs_set/clear_bit to f2fs_test_and_set/clear_bitGu Zheng2014-11-042-4/+4
| | | | | | | | Rename f2fs_set/clear_bit to f2fs_test_and_set/clear_bit, which mean set/clear bit and return the old value, for better readability. Signed-off-by: Gu Zheng <guz.fnst@cn.fujitsu.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

* f2fs: avoid deadlock on init_inode_metadataJaegeuk Kim2014-11-047-22/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, init_inode_metadata does not hold any parent directory's inode page. So, f2fs_init_acl can grab its parent inode page without any problem. But, when we use inline_dentry, that page is grabbed during f2fs_add_link, so that we can fall into deadlock condition like below. INFO: task mknod:11006 blocked for more than 120 seconds.

Suspiciously small, I'd say. Anyway, most of this are a few defconfig updates. Some for omap to deal with kernel binary size (moving ipv6 to module, etc). A larger one for socfpga that refreshes with some churn, but also turns on a few options that makes the newly-added board in my bootfarm usable for testing. OMAP3 will also now warn when booted with legacy (non-DT) boot protocols, hopefully encouraging those who still care about some of those platforms to submit DT support and report bugs where needed. Nothing stops working though, this is just to warn for future deprecation. Beyond this, very few actual bugfixes.

Also let's add a warning about legacy boot being deprecated for omap3. We now have things working with device tree, and only omap3 is still booting in legacy mode. So hopefully this warning will help move the remaining legacy mode users to boot with device tree. As the total reduction of code and static data is somewhere around 20000 lines of code once we remove omap3 legacy mode booting, we really do want to make omap3 to boot also in device tree mode only over the next few merge cycles. * tag 'fixes-against-v3.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (407 commits) ARM: OMAP2+: Warn about deprecated legacy booting mode ARM: omap2plus_defconfig: Fix errors with NAND BCH ARM: omap2plus_defconfig: Fix bloat caused by having ipv6 built-in + Linux 3.18-rc2 Signed-off-by: Olof Johansson <olof@lixom.net>

Only omap3 still has legacy booting still around and we really want to make that device tree only. So let's add a warning about deprecated legacy booting so we get people to upgrade their boards to use device tree based booting and find out about any remaining issues. Note that for most boards we already have the .dts file and those can be booted with without changing the bootloader using the appended DTB mode.

The fix is a trivial Kconfig value fix for an addressing conflict.

It is due to overlap between uart virtual memory defined in DEBUG_UART_VIRT and mapped by debug_ll_io_init() and peripheral bus mapped by pxa_map_io at the same address, 0xf2100000. As hinted by Arnd, map early virtual memory for low level debug on address 0xf6200000, even if that means 2 virtual mappings will give access to the pxa internal UARTs (FFUART, BTUART, STUART, ...). ------------[ cut here ]------------ kernel BUG at /home/lumag/linux/mm/vmalloc.c:1143!
