+rootflags=nr_blocks=0,nr_inodes=0 on the kernel command line, +and then hand these rootflags over to the initramfs (tmpfs) +mount in the same way the kernel hands them over to the block +device rootfs mount. But at least the Debian/m68k initrd also +parses $rootflags from the environment and adds it to the call +to the user-space mount for the eventual root device, which +would make the kernel command line rootflags option be used in +both places (tmpfs and e.g. ext4) which is guaranteed to error +out in at least one of them. + +This change is intended to aid people in a setup where the +initrd is the final root filesystem, i.e. not mounted over. +This is especially useful in automated tests running on qemu +for boards with constrained memory (e.g. 64 MiB on sh4). + +Considering that the initramfs is normally emptied out then +overmounted, this change is probably safe for setups where +initramfs just hosts early userspace, too, since the tmpfs +backing it is not accessible any more later on, AFAICT. + +Signed-off-by: Thorsten Glaser +--- + init/do_mounts.c | 4 ++++ + 1 file changed, 4 insertions(+) + +diff --git a/init/do_mounts.c b/init/do_mounts.c +index 82f2288..55a4cfe 100644 +--- a/init/do_mounts.c ++++ b/init/do_mounts.c +@@ -594,6 +594,7 @@ out: + } + + static bool is_tmpfs; ++static char tmpfs_rootflags[] = "nr_blocks=0,nr_inodes=0"; + static struct dentry *rootfs_mount(struct file_system_type *fs_type, + int flags, const char *dev_name, void *data) + { +@@ -606,6 +607,9 @@ static struct dentry *rootfs_mount(struct file_system_type *fs_type, + if (IS_ENABLED(CONFIG_TMPFS) && is_tmpfs) + fill = shmem_fill_super; + ++ if (is_tmpfs) ++ data = tmpfs_rootflags; ++ + return mount_nodev(fs_type, flags, data, fill); + } + +-- +2.0.0.rc0 + diff --git a/target/linux/patches/4.2.4/regmap-default-on.patch b/target/linux/patches/4.2.4/regmap-default-on.patch new file mode 100644 index 000000000..8d72224bf --- /dev/null +++ b/target/linux/patches/4.2.4/regmap-default-on.patch @@ -0,0 +1,17 @@ +diff -Nur linux-4.1.6.orig/drivers/base/regmap/Kconfig linux-4.1.6/drivers/base/regmap/Kconfig +--- linux-4.1.6.orig/drivers/base/regmap/Kconfig 2015-08-17 05:52:51.000000000 +0200 ++++ linux-4.1.6/drivers/base/regmap/Kconfig 2015-08-29 22:18:50.329683337 +0200 +@@ -3,7 +3,7 @@ + # subsystems should select the appropriate symbols. + + config REGMAP +- default y if (REGMAP_I2C || REGMAP_SPI || REGMAP_SPMI || REGMAP_AC97 || REGMAP_MMIO || REGMAP_IRQ) ++ default y + select LZO_COMPRESS + select LZO_DECOMPRESS + select IRQ_DOMAIN if REGMAP_IRQ +@@ -29,3 +29,4 @@ + + config REGMAP_IRQ + bool ++ default y diff --git a/target/linux/patches/4.2.4/startup.patch b/target/linux/patches/4.2.4/startup.patch new file mode 100644 index 000000000..d396b75e4 --- /dev/null +++ b/target/linux/patches/4.2.4/startup.patch @@ -0,0 +1,37 @@ +diff -Nur linux-3.13.3.orig/init/main.c linux-3.13.3/init/main.c +--- linux-3.13.3.orig/init/main.c 2014-02-13 23:00:14.000000000 +0100 ++++ linux-3.13.3/init/main.c 2014-02-17 11:35:14.000000000 +0100 +@@ -916,6 +917,8 @@ + if (sys_open((const char __user *) "/dev/console", O_RDWR, 0) < 0) + pr_err("Warning: unable to open an initial console.\n"); + ++ printk(KERN_WARNING "Starting Linux (built with OpenADK).\n"); ++ + (void) sys_dup(0); + (void) sys_dup(0); + /* +diff -Nur linux-3.13.6.orig/init/initramfs.c linux-3.13.6/init/initramfs.c +--- linux-3.13.6.orig/init/initramfs.c 2014-03-07 07:07:02.000000000 +0100 ++++ linux-3.13.6/init/initramfs.c 2014-03-15 12:11:31.882731916 +0100 +@@ -622,6 +622,9 @@ + */ + load_default_modules(); + } ++#ifdef CONFIG_DEVTMPFS_MOUNT ++ devtmpfs_mount("dev"); ++#endif + return 0; + } + rootfs_initcall(populate_rootfs); +diff -Nur linux-3.13.6.orig/init/main.c linux-3.13.6/init/main.c +--- linux-3.13.6.orig/init/main.c 2014-03-07 07:07:02.000000000 +0100 ++++ linux-3.13.6/init/main.c 2014-03-15 12:13:16.459024452 +0100 +@@ -924,7 +924,7 @@ + */ + + if (!ramdisk_execute_command) +- ramdisk_execute_command = "/init"; ++ ramdisk_execute_command = "/sbin/init"; + + if (sys_access((const char __user *) ramdisk_execute_command, 0) != 0) { + ramdisk_execute_command = NULL; -- cgit v1.2.3
