mtd: gen_probe: Remove unnecessary OOM messages

2014-03-11T05:42:25+00:00

The site-specific OOM messages are unnecessary, because they duplicate the MM subsystem generic OOM message. Signed-off-by: Jingoo Han Signed-off-by: Brian Norris

mtd: delete non-required instances of include

2014-03-11T05:42:22+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

mtd: jedec_probe: fix LH28F640BF definition

2013-08-05T20:04:17+00:00

Zaurus 5500 contains 2 LH28F640BFHE-PTTL90 (64M 4Mx16) and the LH28F640BFHE-PTTL90.pdf datasheet available on the net shows the exact erasesize and the OTP support. At the moment only jedec_probe can discover the chip and the NOR is mounted read only probably because of wrong vpp. Signed-off-by: Andrea Adami Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: refactor call to request_module

This reduces the size of the stack frame when calling request_module(). Performing the sprintf before the call is not needed. Signed-off-by: Kees Cook Acked-by: Rusty Russell Reviewed-by: James Hogan Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: merge mtdchar module with mtdcore

2013-04-05T12:16:54+00:00

The MTD subsystem has historically tried to be as configurable as possible. The side-effect of this is that its configuration menu is rather large, and we are gradually shrinking it. For example, we recently merged partitions support with the mtdcore. This patch does the next step - it merges the mtdchar module to mtdcore. And in this case this is not only about eliminating too fine-grained separation and simplifying the configuration menu. This is also about eliminating seemingly useless kernel module. Indeed, mtdchar is a module that allows user-space making use of MTD devices via /dev/mtd* character devices. If users do not enable it, they simply cannot use MTD devices at all. They cannot read or write the flash contents. Is it a sane and useful setup? I believe not. And everyone just enables mtdchar. Having mtdchar separate is also a little bit harmful. People sometimes miss the fact that they need to enable an additional configuration option to have user-space MTD interfaces, and then they wonder why on earth the kernel does not allow using the flash? They spend time asking around. Thus, let's just get rid of this module and make it part of mtd core. Note, mtdchar had additional configuration option to enable OTP interfaces, which are present on some flashes. I removed that option as well - it saves a really tiny amount space. [dwmw2: Strictly speaking, you can mount file systems on MTD devices just fine without the mtdchar (or mtdblock) devices; you just can't do other manipulations directly on the underlying device. But still I agree that it makes sense to make this unconditional. And Yay! we get to kill off an instance of checking CONFIG_foo_MODULE, which is an abomination that should never happen.] Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

CONFIG_SYMBOL_PREFIX: cleanup.

2013-03-15T04:39:43+00:00

We have CONFIG_SYMBOL_PREFIX, which three archs define to the string "_". But Al Viro broke this in "consolidate cond_syscall and SYSCALL_ALIAS declarations" (in linux-next), and he's not the first to do so. Using CONFIG_SYMBOL_PREFIX is awkward, since we usually just want to prefix it so something. So various places define helpers which are defined to nothing if CONFIG_SYMBOL_PREFIX isn't set: 1) include/asm-generic/unistd.h defines __SYMBOL_PREFIX. 2) include/asm-generic/vmlinux.lds.h defines VMLINUX_SYMBOL(sym) 3) include/linux/export.h defines MODULE_SYMBOL_PREFIX. 4) include/linux/kernel.h defines SYMBOL_PREFIX (which differs from #7) 5) kernel/modsign_certificate.S defines ASM_SYMBOL(sym) 6) scripts/modpost.c defines MODULE_SYMBOL_PREFIX 7) scripts/Makefile.lib defines SYMBOL_PREFIX on the commandline if CONFIG_SYMBOL_PREFIX is set, so that we have a non-string version for pasting. (arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too). Let's solve this properly: 1) No more generic prefix, just CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX. 2) Make linux/export.h usable from asm. 3) Define VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR(). 4) Make everyone use them.
