2007-03-16[PATCH] gpio_direction_output() needs an initial valueDavid Brownell
It's been pointed out that output GPIOs should have an initial value, to avoid signal glitching ... among other things, it can be some time before a driver is ready. This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.

2007-03-17[MIPS] RTLX: Harden against compiler reordering and optimization.Ralf Baechle
RTLX communication is based on lock-free shared memory buffers. It happened to be working by luck so far but relies on the optimizer doing certain optimizations but no reordering. Fixed by inserting proper barriers in rtlx_read and rtlx_write, and careful pointer dereferencing. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Commit 6d6671066a311703bca1b91645bb1e04cc983387 is incomplete and misses non-r4k CPUs.

2007-03-16[SPARC64]: Get DEBUG_PAGEALLOC working again.David S. Miller
We have to make sure to use base-pagesize TLB entries even during the early transition period where we need TLB miss handling but don't have the kernel page tables setup yet for the linear region. Also, it is necessary therefore to not use the 4MB TSB for these translations, and instead use the normal kernel TSB. This allows us to also get rid of the 4MB tsb for debug builds which shrinks the kernel a little bit. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-03-12[PATCH] Fix VMI and COMPAT_VDSO for 2.6.21Zachary Amsden
VMI is broken under COMPAT_VDSO, as Xen and other non hardware assisted hypervisors will be. I have been working on a fix for this which works for older glibcs that panic when the new relocatable VDSO is used. However, I believe at this time that the fix is going to be too radical to consider at this stage in the release of 2.6.21. We don't expect this config option to be turned on by vendors for new distributions, so at this point we are willing to drop support for it when VMI is compiled in, and work on a patch for 2.6.22 which more fully addresses the problem.
