rtc: fix deadlock

2008-10-09T03:23:00Z

commit 38c052f8cff1bd323ccfa968136a9556652ee420 upstream if get_rtc_time() is _ever_ called with IRQs off, we deadlock badly in it, waiting for jiffies to increment. So make the code more robust by doing an explicit mdelay(20). This solves a very hard to reproduce/debug hard lockup reported by Mikael Pettersson.

vmlinux.lds: move attribute((cold)) functions back into final .text section

2008-08-01T19:43:05Z

commit fb5e2b379732e1a6ea32392980bb42e0212db842 upstream Due to the addition of __attribute__((__cold__)) to a few symbols without adjusting the linker scripts, those symbols currently may end up outside the [_stext,_etext) range, as they get placed in .text.unlikely by (at least) gcc 4.3.0. This may confuse code not only outside of the kernel, symbol_put_addr()'s BUG() could also trigger. Hence we need to add .text.unlikely (and for future uses of __attribute__((__hot__)) also .text.hot) to the TEXT_TEXT() macro. Issue observed by Lukas Lipavsky.

Christoph has moved

2008-07-04T17:40:04Z

Remove all clameter@sgi.com addresses from the kernel tree since they will become invalid on June 27th. Change my maintainer email address for the slab allocators to cl@linux-foundation.org (which will be the new email address for the future).

kbuild: fix a.out.h export to userspace with O= build.

2008-06-27T21:13:54Z

We need to check for existence of the a.out.h header in the source tree, not the object tree, if we want it to get the right answer with O=. Signed-off-by: David Woodhouse Signed-off-by: Sam Ravnborg

types: add C99-style constructors to

2008-05-02T23:18:42Z

Add C99-style constructor macros for fixed types to . Since Linux uses names like "u64" instead of "uint64_t", the constructor macros are called U64_C() instead of UINT64_C() and so forth. These macros allow specific sizes to be specified as U64_C(0x123456789abcdef), without gcc issuing warnings as it will if one writes (u64)0x123456789abcdef. When used from assembly, these macros pass their argument unchanged. Signed-off-by: H. Peter Anvin

types: create

2008-05-02T23:18:19Z

This creates two generic files with common integer definitions; one where 64 bits is "long" (most 64-bit architectures) and one where 64 bits is "long long" (all 32-bit architectures and x86-64.)

rename div64_64 to div64_u64

2008-05-01T15:03:58Z

Rename div64_64 to div64_u64 to make it consistent with the other divide functions, so it clearly includes the type of the divide. Move its definition to math64.h as currently no architecture overrides the generic implementation. They can still override it of course, but the duplicated declarations are avoided.

asm-*/futex.h should include linux/uaccess.h

2008-04-30T15:29:52Z

Lots of asm-*/futex.h call pagefault_enable and pagefault_disable, which are declared in linux/uaccess.h, without including linux/uaccess.h. They all include asm/uaccess.h, so this patch replaces asm/uaccess.h with linux/uaccess.h.
