The function uart_match_port() incorrectly compares the ioremap'd virtual addresses of ports instead of the physical address to find duplicate ports for MMIO based UARTs. This fixes it.

Reading the MSR register on 8250-compatible UARTs results in any modem status interrupts being cleared. To avoid missing any status changes, arrange for get_mctrl() to read the current status via check_modem_status(), which will process any pending state changes for us.

In commit 3D59121003721a8fad11ee72e646fd9d3076b5679c, the x86 and x86-64 <asm/param.h> was changed to include <linux/config.h> for the configurable timer frequency. However, asm/param.h is sometimes used in userland (it is included indirectly from <sys/param.h>), so your commit pollutes the userland namespace with tons of CONFIG_FOO macros. This greatly confuses software packages (such as BusyBox) which use CONFIG_FOO macros themselves to control the inclusion of optional features. After a short exchange, Christoph approved this patch Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

Some G5s still occasionally experience shutdowns due to overtemp conditions despite the recent fix. After analyzing logs from such machines, it appears that the overtemp code is a bit too quick at shutting the machine down when reaching the critical temperature (tmax + 8) and doesn't leave the fan enough time to actually cool it down. This happens if the temperature of a CPU suddenly rises too high in a very short period of time, or occasionally on boot (that is the CPUs are already overtemp by the time the driver loads). This patches makes the code a bit more relaxed, leaving a few seconds to the fans to do their job before kicking the machine shutown.

This is a slightly more complete fix for the previous minimal sysctl string fix. It always terminates the returned string with a NUL, even if the full result wouldn't fit in the user-supplied buffer. The returned length is the full untruncated length, so that you can tell when truncation has occurred. Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

For the sysctl syscall, if the user wants to get the old value of a sysctl entry and set a new value for it in the same syscall, the old value is always overwritten by the new value if the sysctl entry is of string type and if the user sets its strategy to sysctl_string. This issue lies in the strategy being run twice if the strategy is set to sysctl_string, the general strategy sysctl_string always returns 0 if success. Such strategy routines as sysctl_jiffies and sysctl_jiffies_ms return 1 because they do read and write for the sysctl entry. The strategy routine sysctl_string return 0 although it actually read and write the sysctl entry. According to my analysis, if a strategy routine do read and write, it should return 1, if it just does some necessary check but not read and write, it should return 0, for example sysctl_intvec.

The old /proc interfaces were never updated to use loff_t, and are just generally broken. Now, we should be using the seq_file interface for all of the proc files, but converting the legacy functions is more work than most people care for and has little upside.. But at least we can make the non-LFS rules explicit, rather than just insanely wrapping the offset or something. Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

This reverts the series of commits 67dbb4ea 281ab031 47807ce3 that changed the GART VM start offset. It fixed some machines, but seems to continually interact badly with some X versions. Quoth Ben Herrenschmidt: "So I think at this point, the best is that we keep the old bogus code that at least is consistent with the bug in the server. I'm working on a big patch to X that reworks the memory map stuff completely and fixes those issues on the server side, I'll do a DRM patch matching this X fix as well so that the memory map is only ever set in one place and with what I hope is a correct algorithm..."

Today, when compiling UML, I got warnings for two used unexported symbols: readdir64 and truncate64. Indeed, my glibc headers are aliasing readdir to readdir64 and truncate to truncate64 (and so on).

Don't use printk() where "current_thread_info()" is crap. Until when we switch to running on init_stack, current_thread_info() evaluates to crap. Printk uses "current" at times (in detail, ¤t is evaluated with CONFIG_DEBUG_SPINLOCK to check the spinlock owner task). And this leads to random segmentation faults. Exactly, what happens is that ¤t = *(current_thread_info()), i.e. round down $esp and dereference the value. I.e. access the stack below $esp, which causes SIGSEGV on a VM_GROWSDOWN vma (see arch/i386/mm/fault.c).

Noticed by Christophe Zimmerman, this explains the slow mouse movement with 2.6.x kernels. And checking the 2.4.x drivers/sbus/char/sunmouse.c driver shows we always used a 5-byte protocol with Sun mice in the past.

As reported by Jules Villard <jvillard@ens-lyon.fr> and some others, the recent GART aperture start reconfiguration causes problems on some setups. What I _think_ might be happening is that the X server is also trying to muck around with the card memory map and is forcing it back into a wrong setting that also happens to no longer match what the DRM wants to do and blows up. There are bugs all over the place in that code (and still some bugs in the DRM as well anyway). This patch attempts to avoid that by using the largest of the 2 values, which I think will cause it to behave as it used to for you and will still fix the problem with machines that have an aperture size smaller than the video memory.

The below "jumbo" patch fixes the following problems in MLDv2. 1) Add necessary "ntohs" to recent "pskb_may_pull" check [breaks all nonzero source queries on little-endian (!)] 2) Add locking to source filter list [resend of prior patch] 3) fix "mld_marksources()" to a) send nothing when all queried sources are excluded b) send full exclude report when source queried sources are not excluded c) don't schedule a timer when there's nothing to report NOTE: RFC 3810 specifies the source list should be saved and each source reported individually as an IS_IN. This is an obvious DOS path, requiring the host to store and then multicast as many sources as are queried (e.g., millions...). This alternative sends a full, relevant report that's limited to number of sources present on the machine. 4) fix "add_grec()" to send empty-source records when it should The original check doesn't account for a non-empty source list with all sources inactive; the new code keeps that short-circuit case, and also generates the group header with an empty list if needed. 5) fix mca_crcount decrement to be after add_grec(), which needs its original value These issues (other than item #1 ;-) ) were all found by Yan Zheng, much thanks!
