| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | info->mod->name In setup_load_info(), info->name (which contains the name of the module, mostly used for early logging purposes before the module gets set up) gets unconditionally assigned if .modinfo is missing despite the fact that there is an if (!info->name) check near the end of the function. Avoid assigning a placeholder string to info->name if .modinfo doesn't exist, so that we can fall back to info->mod->name later on.

| * export.h: reduce __ksymtab_strings string duplication by using "MS" section ↵Jessica Yu2019-12-162-13/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flags Commit c3a6cf19e695 ("export: avoid code duplication in include/linux/export.h") refactors export.h quite nicely, but introduces a slight increase in memory usage due to using the empty string "" instead of NULL to indicate that an exported symbol has no namespace. As mentioned in that commit, this meant an increase of 1 byte per exported symbol without a namespace. For example, if a kernel configuration has about 10k exported symbols, this would mean that the size of __ksymtab_strings would increase by roughly 10kB. We can alleviate this situation by utilizing the SHF_MERGE and SHF_STRING section flags. SHF_MERGE|SHF_STRING indicate to the linker that the data in the section are null-terminated strings that can be merged to eliminate duplication. More specifically, from the binutils documentation - "for sections with both M and S, a string which is a suffix of a larger string is considered a duplicate. Thus "def" will be merged with "abcdef"; A reference to the first "def" will be changed to a reference to "abcdef"+3". Thus, all the empty strings would be merged as well as any strings that can be merged according to the cited method above. For example, "memset" and "__memset" would be merged to just "__memset" in __ksymtab_strings. As of v5.4-rc5, the following statistics were gathered with x86 defconfig with approximately 10.7k exported symbols. Size of __ksymtab_strings in vmlinux: ------------------------------------- v5.4-rc5: 213834 bytes v5.4-rc5 with commit c3a6cf19e695: 224455 bytes v5.4-rc5 with this patch: 205759 bytes So, we already see memory savings of ~8kB compared to vanilla -rc5 and savings of nearly 18.7kB compared to -rc5 with commit c3a6cf19e695 on top. Unfortunately, as of this writing, strings will not get deduplicated for kernel modules, as ld does not do the deduplication for SHF_MERGE|SHF_STRINGS sections for relocatable files (ld -r), which kernel modules are. A patch for ld is currently being worked on to hopefully allow for string deduplication in relocatable files in the future.

Hovewer, this variant is not optimal for mainly two reasons: * For now, we have 20+ CPUs with such instructions and only two (MIPS R6) without. It will obviously be more effective and straightforward to have an option for these two rather than for the rest. * You can easily miss the fact that you need to select this option when adding a new CPU, while all processors lacking these sets are well-known, so the probability of missing something is way much lower. We can address both points by turning CPU_HAS_LOAD_STORE_LR into opt-out CPU_NO_LOAD_STORE_LR. This also makes MIPS root Kconfig more clear and understandable.

It also supports connecting a SuperIO chip for serial and parallel interfaces. IOC3 is used inside various SGI systemboards and add-on cards with different equipped external interfaces. Support for ethernet and serial interfaces were implemented inside the network driver. This patchset moves out the not network related parts to a new MFD driver, which takes care of card detection, setup of platform devices and interrupt distribution for the subdevices.

This also means we need to mangle addresses for u8 and u16 accesses. The mangling for 16bit has been done aready, but 8bit one was missing. Correcting this causes different addresses for accesses to the SuperIO and local bus of the IOC3 chip. This is fixed by changing byte order in ioc3 and m48rtc_rtc structs.
