* [PATCH] Kconfig fix (sparc32 drivers/char dependencies)Al Viro2005-08-23
| | | | | | | | | since sparc32 Kconfig includes drivers/char/Kconfig (instead of duplicating its parts) we need several new dependencies there to exclude the stuff broken on sparc32 and not excluded by existing dependencies.

* [PATCH] tpm_infineon: Support for new TPM 1.2 and PNPACPIMarcel Selhorst2005-08-05
| | | | | | | | | | | | | | | This patch includes support for the new Infineon Trusted Platform Module SLB 9635 TT 1.2 and does further include ACPI-support for both chip versions (SLD 9630 TT 1.1 and SLB9635 TT 1.2). Since the ioports and configuration registers are not correctly set on some machines, the configuration is now done via PNPACPI, which reads out the correct values out of the DSDT-table. Note that you have to have CONFIG_PNP, CONFIG_ACPI_BUS and CONFIG_PNPACPI enabled to run this driver (assuming that mainboards including a TPM do have the need for ACPI anyway).

* [PATCH] rtc: msleep() cannot be used from interruptPetr Vandrovec2005-08-05
| | | | | | | | | | | | | | | | | | | | | | | | | Since the beginning of July my Opteron box was randomly crashing and being rebooted by hardware watchdog. Today it finally did it in front of me, and this patch will hopefully fix it. The problem is that at the end of June (the 28th, to be exact: commit 47f176fdaf8924bc83fddcf9658f2fd3ef60d573, "[PATCH] Using msleep() instead of HZ") rtc_get_rtc_time was converted to use msleep() instead of busy waiting. But rtc_get_rtc_time is used by hpet_rtc_interrupt, and scheduling is not allowed during interrupt. So I'm reverting this part of original change, replacing msleep() back with busy loop. The original code was busy waiting for up to 20ms, but on my hardware in the worst case update-in-progress bit was asserted for at most 363 passes through loop (on 2GHz dual Opteron), much less than even one jiffie, not even talking about 20ms. So I changed code to just wait only as long as necessary. Otherwise when RTC was set to generate 8192Hz timer, it stopped doing anything for 20ms (160 pulses were skipped!) from time to time, and this is rather suboptimal as far as I can tell.

* [PATCH] ARM: 2833/2: Remove support for WDIOF_MAGICCLOSE from sa1100-wdtIan Campbell2005-08-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Ian Campbell On PXA255 there is no way to disable the watchdog. Turning off OIER[E3] as suggested in the existing comment does not work. I posted a note to the ARM mailing list a little while ago asking for opinions from people using SA1100. There was one reponse from Nico who believes that the SA1100 is the same as the PXA255 in this respect. You also asked me to involve the watchdog maintainer which I tried to do but didn't hear anything back. There are only a couple of other drivers which can't stop the watchdog and there seems to be no consistancy regarding printing an error etc. I decided to print something since that matches the case for all the other drivers when NOWAYOUT is turned on. Also, I changed the device .name to "watchdog" like most of the other watchdogs. udev uses it as the device name (by default) and spaces etc. get in the way. Superceded 2833/1 because 2.6.13-rc4 caused rejects. Signed-off-by: Ian Campbell <icampbell@arcom.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [PATCH] agp: restore APBASE after setting APSIZEMatthew Garrett2005-07-29
| | | | | | | | | | | | | | | | | | | | | | When leaving S3 state, the AGP bridge may not have all PCI configuration registers set in the same way as they were at boot. This should be fixed by pci_restore_state - however, the APBASE register cannot be set to conflict with the APSIZE register. If APSIZE is larger than it was before suspend, pci_restore_state will not restore APBASE correctly. The attached patch adds an extra item to the agp_bridge_data structure and uses it to store the value of APBASE. On resume, this is then written after APSIZE has been set. This patch only touches the path used for Intel chipsets without integrated graphics, and may need to be extended to work with the others. Without this patch, I get the symptoms described in bug 4921 - APBASE ends up overlapping various PCI devices, and as a result they fail to work after resume.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `gcc -W' likes to complain if the static keyword is not at the beginning of the declaration. This patch fixes all remaining occurrences of "inline static" up with "static inline" in the entire kernel tree (140 occurrences in 47 files). While making this change I came across a few lines with trailing whitespace that I also fixed up, I have also added or removed a blank line or two here and there, but there are no functional changes in the patch.

BTW the core problem is that part of this should be handled in the receive_buf path, but for this it has to return the number of written characters, as the amount of written characters may not be the same as the amount of characters going into the write buffer, so the receive_room() usage in pty_write() is not really reliable. Alan said: The problem looks valid. The behaviour of 'traditional unix' appears to be the following If you exceed the line limit then beep and drop the character Always allow EOL to complete a canonical line input Always do signal/control processing if enabled Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
