ia64: restore symbol versions for symbols defined in assembly

2017-04-14T01:19:49Z

The ia64 build generates many warnings like this: WARNING: EXPORT symbol "empty_zero_page" [vmlinux] version generation failed, symbol will not be versioned. Besides adding the necessary header this also requires fiddling with some explicit .S -> .o rules. Cc: IA64-ML Signed-off-by: Jan Beulich Signed-off-by: Tony Luck Signed-off-by: Linus Torvalds

[kbuild] handle exports in lib-y objects reliably

2016-08-08T03:46:30Z

Collect the symbols exported by anything that goes into lib.a and add an empty object (lib-exports.o) with explicit undefs for each of those to obj-y. That allows to relax the rules regarding the use of exports in lib-* objects - right now an object with export can be in lib-* only if we are guaranteed that there always will be users in built-in parts of the tree, otherwise it needs to be in obj-*. As the result, we have an unholy mix of lib- and obj- in lib/Makefile and (especially) in arch/*/lib/Makefile. Moreover, a change in generic part of the kernel can lead to mysteriously missing exports on some configs. With this change we don't have to worry about that anymore. One side effect is that built-in.o now pulls everything with exports from the corresponding lib.a (if such exists). That's exactly what we want for linking vmlinux and fortunately it's almost the only thing built-in.o is used in. arch/ia64/hp/sim/boot/bootloader is the only exception and it's easy to get rid of now - just turn everything in arch/ia64/lib into lib-* and don't bother with arch/ia64/lib/built-in.o anymore.

[IA64] export copy_page() to modules

2007-12-08T00:10:19Z

With the unionfs patch applied I get ERROR: "copy_page" [fs/unionfs/unionfs.ko] undefined! the other architectures (some, at least) export copy_page() so I guess ia64 should also do so. To do this we need to move the copy_page() functions out of lib.a and into built-in.o and add the EXPORT_SYMBOL().

[IA64] always build arch/ia64/lib/xor.o

2007-03-06T22:48:52Z

Always build ia64 xor.o because multiple config options now depend on it. Necessary to build .20-mm* on ia64 when, e.g., CONFIG_ASYNC_TX_DMA is defined. Don't know if '_ASYNC_TX_DMA makes sense on ia64. If not, maybe Kconfig should preclude it. Could have defined a Kconfig option that defaults to true if MD_RAID456 || ASYNC_TX_DMA to control building of xor.o, but xor.o is only 848 bytes and this IS ia64...

Update from upstream with manual merge of Yasunori Goto's

2005-10-20T17:41:44Z

changes to swiotlb.c made in commit 281dd25cdc0d6903929b79183816d151ea626341 since this file has been moved from arch/ia64/lib/swiotlb.c to lib/swiotlb.c Signed-off-by: Tony Luck

[PATCH] swiotlb: move from arch/ia64/lib/ to lib/

2005-09-29T21:42:42Z

The swiotlb implementation is shared by both IA-64 and EM64T. However, the source itself lives under arch/ia64. This patch moves swiotlb.c from arch/ia64/lib to lib/ and fixes-up the appropriate Makefile and Kconfig files. No actual changes are made to swiotlb.c. Signed-off-by: John W.

[LIB]: Consolidate _atomic_dec_and_lock()

2005-09-15T04:47:01Z

Several implementations were essentialy a common piece of C code using the cmpxchg() macro. Put the implementation in one spot that everyone can share, and convert sparc64 over to using this. Alpha is the lone arch-specific implementation, which codes up a special fast path for the common case in order to avoid GP reloading which a pure C version would require. Signed-off-by: David S.

[IA64] Delete erroneous copy_page.o in global lib-y list

2005-08-26T23:01:25Z

copy_page.o appeared twice in arch/ia64/lib/Makefile. The one in global lib-y is wrong where it should be just in lib-$(CONFIG_ITANIUM). Both copy_page.o and copy_page_mck.o are build for Itanium2 processor and the link order will pick up the low performing copy_page function (originally written for itanium processor). In this case, we really want the copy_page_mck.o for optimized version. Signed-off-by: Kenneth Chen Signed-off-by: Tony Luck
