2006-10-20[PATCH] bug: nfsd/nfs4xdr.c misuse of ERR_PTR()Al Viro
a) ERR_PTR(nfserr_something) is a bad idea; IS_ERR() will be false for it. b) mixing nfserr_.... with -EOPNOTSUPP is even worse idea. nfsd4_path() does both; caller expects to get NFS protocol error out it if anything goes wrong, but if it does we either do not notice (see (a)) or get host-endian negative (see (b)). IOW, that's a case when we can't use ERR_PTR() to return error, even though we return a pointer in case of success.

If invalidate_inode_pages2() fails, then it should in principle just be because the current process was signalled. In that case, we just want to ensure that the inode's page cache remains marked as invalid. Also add a helper to allow the O_DIRECT code to simply mark the page cache as invalid once it is finished writing, instead of calling invalidate_inode_pages2() itself.

Move the call to dec_zone_page_state so that it occurs while req->wb_page is still valid. - Calling nfs_clear_page_writeback is unnecessary since the radix tree tags will have been cleared by the call to nfs_inode_remove_request.

2006-10-20[PATCH] acpi memory hotplug: remove strange add_memory fail messageYasunori Goto
I wrote a patch to avoid redundant memory hot-add call at boot time. This was cause of strange fail message of memory hotplug like "ACPI: add_memory failed". Memory is recognized by early boot code with EFI/E820. But, if DSDT describes memory devices for them, then hot-add code is called for already recognized memory, and it shows fail messages with -EEXIST. So, sys admin will misunderstand this message as something wrong by it. This patch avoids them by preventing redundant hot-add call until completion of driver initialization.

2006-10-20[PATCH] fix "ACPI: Processor native C-states using MWAIT"Darrick J. Wong
This patch breaks C-state discovery on my IBM IntelliStation Z30 because the return value of acpi_processor_get_power_info_fadt is not assigned to "result" in the case that acpi_processor_get_power_info_cst returns -ENODEV. Thus, if ACPI provides C-state data via the FADT and not _CST (as is the case on this machine), we incorrectly exit the function with -ENODEV after reading the FADT.

2006-10-20[PATCH] uml: use DEFCONFIG_LIST to avoid reading host's configPaolo 'Blaisorblade' Giarrusso
This should make sure that, for UML, host's configuration files are not considered, which avoids various pains to the user. Our dependency are such that the obtained Kconfig will be valid and will lead to successful compilation - however they cannot prevent an user from disabling any boot device, and if an option is not set in the read .config (say /boot/config-XXX), with make menuconfig ARCH=um, it is not set. This always disables UBD and all console I/O channels, which leads to non-working UML kernels, so this bothers users - especially now, since it will happen on almost every machine (/boot/config-`uname -r` exists almost on every machine). It can be workarounded with make defconfig ARCH=um, but it is non-obvious and can be avoided, so please _do_ merge this patch. Given the existence of options, it could be interesting to implement (additionally) "option required" - with it, Kconfig will refuse reading a .config file (from wherever it comes) if the given option is not set. With this, one could mark with it the option characteristic of the given architecture (it was an old proposal of Roman Zippel, when I pointed out our problem): config UML option required default y However this should be further discussed: *) for x86, it must support constructs like: ==arch/i386/Kconfig== config 64BIT option required default n where Kconfig must require that CONFIG_64BIT is disabled or not present in the read .config. *) do we want to do such checks only for the starting defconfig or also for .config? Which leads to: *) I may want to port a x86_64 .config to x86 and viceversa, or even among more different archs. Should that be allowed, and in which measure (the user may force skipping the check for a .config or it is only given a warning by default)?

2006-10-20[PATCH] uml: reenable compilation of enable_timer, disabled by mistakePaolo 'Blaisorblade' Giarrusso
