| * [POWERPC] Fix bugs in the hypervisor call stats codeAnton Blanchard2007-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were a few issues with the HCALL_STATS code: - PURR cpu feature checks were backwards - We iterated one entry off the end of the hcall_stats array - Remove dead update_hcall_stats() function prototype I noticed one thing while debugging, and that is we call H_ENTER (to set up the MMU hashtable in early init) before we have done the cpu fixups. This means we will execute the PURR SPR reads even on a CPU that isnt capable of it. I wonder if we can move the CPU feature fixups earlier.

| * [POWERPC] Fix corruption in hcall9Anton Blanchard2007-01-09
| | | | | | | | | | | | | | | | | | | | | | | | It looks to me like we are corrupting r12 in the hcall9 function. Although we have r0 free we cant use offsets against it, so save away r12 in there instead. r12 holds the ninth return value from the hypervisor call, so without this fix, the caller will see the wrong value for the ninth element in the array that gets the return values.

Since we can now run the same kernel on legacy iSeries and other machines, we currently get the /proc/iSeries directory and the files in it on non-iSeries machines, and accessing them causes an oops in some cases. This and the following patches make sure that these files are not created on non-iSeries machines, thus avoiding the oops.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using device_initcall makes it happen for every platform that compiles this file in. This is really bad, for obvious reasons. Instead, we use the .init field of the machine description. If the platform needs the hook to do something specific it can provides its own function and call mpc52xx_declare_of_platform_devices from there. If not, the mpc52xx_declare_of_platform_devices function can directly be used as the init hook.

| * [POWERPC] Fix manual assembly WARN_ON() in enter_rtas().David Woodhouse2007-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we switched over to the generic BUG mechanism we forgot to change the assembly code which open-codes a WARN_ON() in enter_rtas(), so the bug table got corrupted. This patch provides an EMIT_BUG_ENTRY macro for use in assembly code, and uses it in entry_64.S. Tested with CONFIG_DEBUG_BUGVERBOSE on ppc64 but not without -- I tried to turn it off but it wouldn't go away; I suspect Aunt Tillie probably needed it. This version gets __FILE__ and __LINE__ right in the assembly version -- rather than saying include/asm-powerpc/bug.h line 21 every time which is a little suboptimal.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The powerpc specific version of hugetlb_get_unmapped_area() makes some unwarranted assumptions about what checks have been made to its parameters by its callers. This will lead to a BUG_ON() if a 32-bit process attempts to make a hugepage mapping which extends above TASK_SIZE (4GB). I'm not sure if these assumptions came about because they were valid with earlier versions of the get_unmapped_area() path, or if it was always broken. Nonetheless this patch fixes the logic, and removes the crash. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

|/ | | | | | | | | | | | | | | | | | | | The sis96x SMBus PCI device depends on two different quirks to run in a specific order. Apart from being fragile, this was found to actually break on (at least) recent FC4, FC5, and FC6 kernels. This patch fixes the quirks so that they work without relying on the compiler and/or linker to put them in any specific order. http://lists.lm-sensors.org/pipermail/lm-sensors/2006-April/015962.html https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189719 I tested this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fuse does not work on ARM due to cache incoherency issues - fuse wants to use get_user_pages() to copy data from the current process into kernel space. However, since this accesses userspace via the kernel mapping, the kernel mapping can be out of date wrt data written to userspace. This can lead to unpredictable behaviour (in the case of fuse) or data corruption for direct-IO. This resolves debian bug #402876 Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * | [ARM] pass vma for flush_anon_page()Russell King2007-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since get_user_pages() may be used with processes other than the current process and calls flush_anon_page(), flush_anon_page() has to cope in some way with non-current processes. It may not be appropriate, or even desirable to flush a region of virtual memory cache in the current process when that is different to the process that we want the flush to occur for. Therefore, pass the vma into flush_anon_page() so that the architecture can work out whether the 'vmaddr' is for the current process or not. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit b026872601976f666bae77b609dc490d1834bf77, which has been linked to several problem reports with IO-APIC and the timer. Machines either don't boot because the timer doesn't happen, or we get double timer interrupts because we end up double-routing the timer irq through multiple interfaces. See for example http://lkml.org/lkml/2006/12/16/101 http://lkml.org/lkml/2007/1/3/9 http://bugzilla.kernel.org/show_bug.cgi?id=7789 about some of the discussion. Patches to fix this cleanup exist (and have been confirmed to work fine at least for some of the affected cases) and we'll revisit it for 2.6.21, but this late in the -rc series we're better off just reverting the incomplete commit that caused the problems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 59287c0913cc9a6c75712a775f6c1c1ef418ef3b. Hugh Dickins reports that it causes random failures on x86 with SuSE 10.2, and points out "Isn't that randomization, anywhere from 0x10000 to ELF_ET_DYN_BASE, sure to place the ET_DYN from time to time just where the comment says it's trying to avoid? I assume that somehow results in the error reported." (where the comment in question is the existing comment in the source code about mmap/brk clashes).
