* [PATCH] ramdisk blocksize Kconfig entryNathan Scott2006-07-15
| | | | | | | | | | | | | | | | | Make the ramdisk blocksize configurable at kernel compilation time rather than only at boot or module load time, like a couple of the other ramdisk options. I found this handy awhile back but thought little of it, until recently asked by a few of the testing folks here to be able to do the same thing for their automated test setups. The Kconfig comment is largely lifted from comments in rd.c, and hopefully this will increase the chances of making folks aware that the default value often isn't a great choice here (for increasing values of PAGE_SIZE, even moreso).

* [PATCH] hdrinstall: remove asm/io.h from user visibilityDavid Woodhouse2006-07-15
| | | | | | | | | | | There's no excuse for userspace abusing this kernel header -- the kernel's headers are not intended to provide a library of helper routines for userspace. Using <asm/io.h> from userspace is broken on most architectures anyway. Just say 'no'.

* [PATCH] hdrinstall: remove asm/atomic.h from user visibilityDavid Woodhouse2006-07-15
| | | | | | | | | | | | This isn't suitable for userspace to see -- the kernel headers are not a random library of stuff for userspace; they're only there to define the kernel<->user ABI for system libraries and tools. Anything which _was_ abusing asm/atomic.h from userspace was probably broken anyway -- as it often didn't even give atomic operation.

* [PATCH] null-terminate over-long /proc/kallsyms symbolsAndreas Gruenbacher2006-07-15
| | | | | | | | | | | | | | | | | Got a customer bug report (https://bugzilla.novell.com/190296) about kernel symbols longer than 127 characters which end up in a string buffer that is not NULL terminated, leading to garbage in /proc/kallsyms. Using strlcpy prevents this from happening, even though such symbols still won't come out right. A better fix would be to not use a fixed-size buffer, but it's probably not worth the trouble. (Modversion'ed symbols even have a length limit of 60.)

* [PATCH] i386: remove redundant might_sleep() in user accessors.Vadim Lobanov2006-07-15
| | | | | | | | | | | | On i386, the user space accessor functions copy_from/to_user() both invoke might_sleep(), do a quick sanity check, and then pass the work on to their __copy_from/to_user() counterparts, which again invoke might_sleep(). Given that no actual work happens between these two calls, it is best to eliminate one of the redundant might_sleep()s.

* [PATCH] i386 kexec: allow the kexec on panic support to compile on voyagerEric W. Biederman2006-07-15
| | | | | | | | | | | | | | | | | This patch removes the foolish assumption that SMP implied local apics. That assumption is not-true on the Voyager subarch. This makes that dependency explicit, and allows the code to build. What gets disabled is just an optimization to get better crash dumps so the support should work if there is a kernel that will initialization on the voyager subarch under those harsh conditions. Hopefully we can figure out how to initialize apics in init_IRQ and remove the need to disable io_apics and this dependency. Signed-off-by: Eric W.

* [PATCH] ia64: race flushing icache in COW pathAnil Keshavamurthy2006-07-15
| | | | | | | | | | | | | | | | | | | | | | | | There is a race condition that showed up in a threaded JIT environment. The situation is that a process with a JIT code page forks, so the page is marked read-only, then some threads are created in the child. One of the threads attempts to add a new code block to the JIT page, so a copy-on-write fault is taken, and the kernel allocates a new page, copies the data, installs the new pte, and then calls lazy_mmu_prot_update() to flush caches to make sure that the icache and dcache are in sync. Unfortunately, the other thread runs right after the new pte is installed, but before the caches have been flushed. It tries to execute some old JIT code that was already in this page, but it sees some garbage in the i-cache from the previous users of the new physical page. Fix: we must make the caches consistent before installing the pte. This is an ia64 only fix because lazy_mmu_prot_update() is a no-op on all other architectures.
