2008-11-27[ARM] copypage: provide our own copy_user_highpage()Russell King
We used to override the copy_user_page() function. However, this is not only inefficient, it also causes additional complexity for highmem support, since we convert from a struct page to a kernel direct mapped address and back to a struct page again. Moreover, with highmem support, we end up pointlessly setting up kmap entries for pages which we're going to remap. So, push the kmapping down into the copypage implementation files where it's required. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-11-27Allow architectures to override copy_user_highpage()Russell King
With aliasing VIPT cache support, the ARM implementation of clear_user_page() and copy_user_page() sets up a temporary kernel space mapping such that we have the same cache colour as the userspace page. This avoids having to consider any userspace aliases from this operation. However, when highmem is enabled, kmap_atomic() have to setup mappings. The copy_user_highpage() and clear_user_highpage() call these functions before delegating the copies to copy_user_page() and clear_user_page(). The effect of this is that each of the *_user_highpage() functions setup their own kmap mapping, followed by the *_user_page() functions setting up another mapping. This is rather wasteful. Thankfully, copy_user_highpage() can be overriden by architectures by defining __HAVE_ARCH_COPY_USER_HIGHPAGE. However, replacement of clear_user_highpage() is more difficult because its inline definition is not conditional. It seems that you're expected to define __HAVE_ARCH_ALLOC_ZEROED_USER_HIGHPAGE and provide a replacement __alloc_zeroed_user_highpage() implementation instead. The allocation itself is fine, so we don't want to override that. What we really want to do is to override clear_user_highpage() with our own version which doesn't kmap_atomic() unnecessarily. Other VIPT architectures (PARISC and SH) would also like to override this function as well.

2008-11-27udf: Fix BUG_ON() in destroy_inode()Jan Kara
udf_clear_inode() can leave behind buffers on mapping's i_private list (when we truncated preallocation). Call invalidate_inode_buffers() so that the list is properly cleaned-up before we return from udf_clear_inode(). This is ugly and suggest that we should cleanup preallocation earlier than in clear_inode() but currently there's no such call available since drop_inode() is called under inode lock and thus is unusable for disk operations.

The s390 implementation of sched_clock uses the store clock instruction and subtracts jiffies_timer_cc. jiffies_timer_cc is a local variable in arch/s390/kernel/time.c and only used for sched_clock and monotonic clock. For historical reasons there is an offset on that value. With todays code this offset is unnecessary. By removing that offset we can get a sched_clock which returns the nanoseconds after time_init. This improves CONFIG_PRINTK_TIME. Since sched_clock is the only user, I have also renamed jiffies_timer_cc to sched_clock_base_cc. In addition, the local variable init_timer_cc is redundant and can be romved as well.

2008-11-27[S390] fix system call parameter functions.Martin Schwidefsky
syscall_get_nr() currently returns a valid result only if the call chain of the traced process includes do_syscall_trace_enter(). But collect_syscall() can be called for any sleeping task, the result of syscall_get_nr() in general is completely bogus. To make syscall_get_nr() work for any sleeping task the traps field in pt_regs is replace with svcnr - the system call number the process is executing. If svcnr == 0 the process is not on a system call path. The syscall_get_arguments and syscall_set_arguments use regs->gprs[2] for the first system call parameter. This is incorrect since gprs[2] may have been overwritten with the system call number if the call chain includes do_syscall_trace_enter. Use regs->orig_gprs2 instead.

2008-11-26ACPI: thinkpad-acpi: fix fan sleep/resume pathHenrique de Moraes Holschuh
This fixes a regression from v2.6.27, caused by commit 5814f737e1cd2cfa2893badd62189acae3e1e1fd, "ACPI: thinkpad-acpi: attempt to preserve fan state on resume". It is possible for fan_suspend() to fail to properly initialize fan_control_desired_level as required by fan_resume(), resulting on the fan always being set to level 7 on resume if the user didn't touch the fan controller. In order to get fan sleep/resume handling to work right: 1. Fix the fan_suspend handling of the T43 firmware quirk. If it is still undefined, we didn't touch the fan yet and that means we have no business doing it on resume. 2. Store the fan level on its own variable to avoid any possible issues with hijacking fan_control_desired_level (which isn't supposed to have anything other than 0-7 in it, anyway). 3. Change the fan_resume code to me more straightforward to understand (although we DO optimize the boolean logic there, otherwise it looks disgusting). 4. Add comments to help understand what the code is supposed to be doing. 5. Change fan_set_level to be less strict about how auto and full-speed modes are requested. http://bugzilla.kernel.org/show_bug.cgi?id=11982 Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Reported-by: Tino Keitel <tino.keitel@tikei.de> Signed-off-by: Len Brown <len.brown@intel.com>

2008-11-26ACPI suspend: Blacklist boxes that require us to set SCI_EN directly on resumeRafael J. Wysocki
Some Apple boxes evidently require us to set SCI_EN on resume directly, because if we don't do that, they hung somewhere in the resume code path. Moreover, on these boxes it is not sufficient to use acpi_enable() to turn ACPI on during resume. All of this is against the ACPI specification which states that (1) the BIOS is supposed to return from the S3 sleep state with ACPI enabled (SCI_EN set) and (2) the SCI_EN bit is owned by the hardware and we are not supposed to change it. For this reason, blacklist the affected systems so that the SCI_EN bit is set during resume on them. [NOTE: Unconditional setting SCI_EN for all system on resume doesn't work, because it makes some other systems crash (that's to be expected). Also, it is not entirely clear right now if all of the Apple boxes require this workaround.] This patch fixes the recent regression tracked as http://bugzilla.kernel.org/show_bug.cgi?id=12038 Signed-off-by: Rafael J.

2008-11-26parisc: struct device - replace bus_id with dev_name(), dev_set_name()Kay Sievers
(I did not compile or test it, please let me know, or help fixing it, if something is wrong with the conversion) This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

2008-11-26parisc: fix kernel crash when unwinding a userspace processHelge Deller
Any user on existing parisc 32- and 64bit-kernels can easily crash the kernel and as such enforce a DSO. A simple testcase is available here: http://gsyprf10.external.hp.com/~deller/crash.tgz The problem is introduced by the fact, that the handle_interruption() crash handler calls the show_regs() function, which in turn tries to unwind the stack by calling parisc_show_stack(). Since the stack contains userspace addresses, a try to unwind the stack is dangerous and useless and leads to the crash. The fix is trivial: For userspace processes a) avoid to unwind the stack, and b) avoid to resolve userspace addresses to kernel symbol names. While touching this code, I converted print_symbol() to %pS printk formats and made parisc_show_stack() static. An initial patch for this was written by Kyle McMartin back in August: http://marc.info/?l=linux-parisc&m=121805168830283&w=2 Compile and run-tested with a 64bit parisc kernel.

__kernel_time_t is always long on PA-RISC, irrespective of CONFIG_64BIT, hence move it out of the #ifdef CONFIG_64BIT / #else / #endif block. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>

2008-11-26[CIFS] fix regression in cifs_write_begin/cifs_write_endJeff Layton
The conversion to write_begin/write_end interfaces had a bug where we were passing a bad parameter to cifs_readpage_worker. Rather than passing the page offset of the start of the write, we needed to pass the offset of the beginning of the page. This was reliably showing up as data corruption in the fsx-linux test from LTP. It also became evident that this code was occasionally doing unnecessary read calls. Optimize those away by using the PG_checked flag to indicate that the unwritten part of the page has been initialized.

2008-11-26drm/i915: Save/restore HWS_PGA on suspend/resumePeng Li
It fixes suspend/resume failure of xf86-video-intel dri2 branch. As dri2 branch doesn't call I830DRIResume() to restore hardware status page anymore, we need to preserve this register across suspend/resume.
