* f2fs: add stat info for inline_dentry inodesJaegeuk Kim2014-11-045-3/+22

* 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. Tainted: G OE 3.17.0-rc1+ #13 "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. mknod D ffff88003fc94580 0 11006 11004 0x00000000 ffff880007717b10 0000000000000002 ffff88003c323220 ffff880007717fd8 0000000000014580 0000000000014580 ffff88003daecb30 ffff88003c323220 ffff88003fc94e80 ffff88003ffbb4e8 ffff880007717ba0 0000000000000002 Call Trace: [<ffffffff8173dc40>] ? bit_wait+0x50/0x50 [<ffffffff8173d4cd>] io_schedule+0x9d/0x130 [<ffffffff8173dc6c>] bit_wait_io+0x2c/0x50 [<ffffffff8173da3b>] __wait_on_bit_lock+0x4b/0xb0 [<ffffffff811640a7>] __lock_page+0x67/0x70 [<ffffffff810acf50>] ? autoremove_wake_function+0x40/0x40 [<ffffffff811652cc>] pagecache_get_page+0x14c/0x1e0 [<ffffffffa029afa9>] get_node_page+0x59/0x130 [f2fs] [<ffffffffa02a63ad>] read_all_xattrs+0x24d/0x430 [f2fs] [<ffffffffa02a6ca2>] f2fs_getxattr+0x52/0xe0 [f2fs] [<ffffffffa02a7481>] f2fs_get_acl+0x41/0x2d0 [f2fs] [<ffffffff8122d847>] get_acl+0x47/0x70 [<ffffffff8122db5a>] posix_acl_create+0x5a/0x150 [<ffffffffa02a7759>] f2fs_init_acl+0x29/0xcb [f2fs] [<ffffffffa0286a8d>] init_inode_metadata+0x5d/0x340 [f2fs] [<ffffffffa029253a>] f2fs_add_inline_entry+0x12a/0x2e0 [f2fs] [<ffffffffa0286ea5>] __f2fs_add_link+0x45/0x4a0 [f2fs] [<ffffffffa028b5b6>] ? f2fs_new_inode+0x146/0x220 [f2fs] [<ffffffffa028b816>] f2fs_mknod+0x86/0xf0 [f2fs] [<ffffffff811e3ec1>] vfs_mknod+0xe1/0x160 [<ffffffff811e4b26>] SyS_mknod+0x1f6/0x200 [<ffffffff81741d7f>] tracesys+0xe1/0xe6 Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

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. A PXA fix for DEBUG_LL boot hangs, a missing terminting entry in a dt_match array on RealView a MTD fix on OMAP with NAND" [ Obviously missed rc3, will make rc4 instead ;) ] * tag 'armsoc-for-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: MAINTAINERS: drop list entry for davinci ARM: OMAP2+: Warn about deprecated legacy booting mode ARM: omap2plus_defconfig: Fix errors with NAND BCH ARM: multi_v7_defconfig: fix support for APQ8084 soc: versatile: Add terminating entry for realview_soc_of_match ARM: ixp4xx: remove compilation warnings in io.h MAINTAINERS: Add Soren as reviewer for Zynq ARM: omap2plus_defconfig: Fix bloat caused by having ipv6 built-in ARM: socfpga_defconfig: Update defconfig for SoCFPGA ARM: pxa: fix hang on startup with DEBUG_LL

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.

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!

With the restructuring of the m25p80.c driver and the SPI NOR library framework, we omitted proper listing of the SPI device IDs. This means m25p80.c wouldn't auto-load (modprobe) properly when built as a module. For now, we duplicate the device IDs into both modules. - The OMAP / ELM modules were depending on an implicit link ordering. Use deferred probing so that the new link order (in 3.18-rc) can still allow for successful probing. - Fix suspend/resume support for LH28F640BF NOR flash" * tag 'for-linus-20141102' of git://git.infradead.org/linux-mtd: mtd: cfi_cmdset_0001.c: fix resume for LH28F640BF chips mtd: omap: fix mtd devices not showing up mtd: m25p80,spi-nor: Fix module aliases for m25p80 mtd: spi-nor: make spi_nor_scan() take a chip type name, not spi_device_id mtd: m25p80: get rid of spi_get_device_id

An example of this can be found in the SA-1100 Developer's Manual at 9.5.3.3 where the second step of the Sleep Shutdown Sequence is described: "An internal reset is applied to the SA-1100. All units are reset...". As workaround we refresh the PCR value as done initially on chip setup. This behavior and the fix are confirmed by our tests done on 2 different Zaurus collie units with kernel 3.17.

The MODULE_DEVICE_TABLE() macro doesn't work with extern definitions, but its use was also removed at the same time. Now if m25p80 is built as a module it doesn't get the necessary aliases to be loaded automatically. A clean solution to this will involve defining the list of device IDs in spi-nor.h and removing struct spi_device_id from the spi-nor API, but this is quite a large change. As a quick fix suitable for stable, copy the device IDs back into m25p80.
