With these functions implemented we cooperate better with the generic timekeeping code. This obsoletes the need for the timer sysdev as a bonus. Signed-off-by:

The entries are only 32-bit, so restrict the virtual address to stay below 0xffff_ffff. With KERNELBASE set to 0xc000_0000, this in effect restricts access to the first 1GB of real memory. Make setup_kcore conditional on CONFIG_PROC_KCORE for both 32/64. Signed-off-by:

Currently the prep_defconfig in arch/ppc won't build due to swsusp being broken. This patch avoids the problem by essentially disabling all power management on those platforms left in arch/ppc. Signed-off-by: -

Linus made this suggestion for the x86 merge and this starts the process for powerpc. We assume that CONFIG_PPC64 implies CONFIG_PPC_MERGE and CONFIG_PPC_STD_MMU_32 implies CONFIG_PPC_STD_MMU. Signed-off-by:

Move out the old-style exception parsers to a separate function, and don't call it on platforms that have a platform-specific handler. It would make sense to move out the generic versions into their platforms instead, but that can be done gradually down the road. Signed-off-by:

This provides an implementation of the <linux/clk.h> interface for arch/powerpc using a set of function pointers in clk_functions. Platforms that want to support this interface should fill clk_functions and select CONFIG_PPC_CLOCK in Kconfig. Signed-off-by:

In the MPIC U3 MSI code, we call u3msi_compose_msi_msg() once for each MSI. This is overkill, as the address is per pci device, not per MSI. So setup the address once, and just set the data per MSI. Signed-off-by:

Currently rtas_change_msi() returns either the error code from RTAS, or if the RTAS call succeeded the number of irqs that were configured by RTAS. This makes checking the return value more complicated than it needs to be. Instead, have rtas_change_msi() check that the number of irqs configured by RTAS is equal to what we requested - and return an error otherwise. This makes the return semantics match the usual 0 for success, something else for error. Signed-off-by:

It seems that some versions of firmware will report a device node status as the string "okay". As we are not expecting this string, the device node will be ignored by the EEH subsystem. Which means EEH will not be enabled. When EEH is not enabled, PCI errors will be converted into Machine Check exceptions, and we'll have a very unhappy system. Signed-off-by:

> ------------[ cut here ]------------ > Badness at arch/powerpc/kernel/smp.c:202 comes when smp_call_function_map() has been called with irqs disabled, which is illegal. However, there is a special case, the panic() codepath, when we do not want to warn about this -- warning at that time is pointless anyway, and only serves to scroll away the *real* cause of the panic and distracts from the real bug. * So let's extract the WARN_ON() from smp_call_function_map() into all its callers -- smp_call_function() and smp_call_function_single() * Also, introduce another caller of smp_call_function_map(), namely __smp_call_function() (and make smp_call_function() a wrapper over this) which does *not* warn about disabled irqs * Use this __smp_call_function() from the panic codepath's smp_send_stop() We also end having to move code of smp_send_stop() below the definition of __smp_call_function().

This patch fixes arch/ppc kernels, at least for prep subarch, after build-id addition. Without this, kernels were 3 times the size and bootloader refused to load them. Now they are back to normal again. Tested only with Roland McGrath's "Use LDFLAGS_MODULE only for .ko links" patch applied - boots and works fine. Signed-off-by:

When a Fn key is used in combination with another key in ADB keyboards it will generate a Fn event and then a second event that can be a different key than pressed (Fn + F1 for instance can generate Fn + brightness down if it's configured like that). This enables the reporting of the Fn key to the input system. As Fn is a dead key for most purposes, it's useful to report it so applications can make use of it. One example is apple_mouse (https://jake.ruivo.org/uinputd/trunk/apple_mouse/) that emulates the second and third keys using a combination of keyboard keys and the mouse button. Other applications may use the KEY_FN as a modifier as well. I've been updating and using this patch for months without problems. Signed-off-by:

Pretty much everyone uses "__attribute__" or "attribute", no one uses "__attribute". This tweaks the three places in asm-powerpc where this comes up. While only asm-powerpc/types.h is interesting (for userspace), I did asm-powerpc/processor.h as well for consistency. Signed-off-by:

Commit 69331af7, "Fixes and cleanups for earlyprintk aka boot console", resulted in printk output prior to the initialization of the mpsc console driver not being printed. That commit causes the mpsc's CON_PRINTBUFFER flag to be cleared since udbg should have printed the previous output. I guess we can no longer ignore udbg. :) This patch provides udbg_putc() and udbg_getc() functions for the Marvell mv64x60 chips. These functions are enabled if an mv64x60 port is to be used as the console as determined from the device tree. Signed-off-by:

This adds the option for the pmac_zilog driver to use the major/minor numbers recently allocated specifically for it (/dev/ttyPZn) instead of the /dev/ttySn numbers. The advantage of doing this is that it allows the pmac_zilog and 8250 drivers to coexist. The disadvantage of doing this is that it is a user-visible ABI change and it will break existing working setups on powermacs, and could be confusing to users. Signed-off-by:

This patch includes a whole batch of smallish cleanups for drivers/mtd/physmap_of.c. - A bunch of uneeded #includes are removed - We switch to the modern linux/of.h etc. in place of asm/prom.h - Use some helper macros to avoid some ugly inline #ifdefs - A few lines of unreachable code are removed - A number of indentation / line-wrapping fixes - More consistent use of kernel idioms such as if (!p) instead of if (p == NULL) - Clarify some printk()s and other informative strings. - parse_obsolete_partitions() now returns 0 if no partition information is found, instead of returning -ENOENT which the caller had to handle specially. - (the big one) Despite the name, this driver really has nothing to do with drivers/mtd/physmap.c. The fact that the flash chips must be physically direct mapped is a constrant, but doesn't really say anything about the actual purpose of this driver, which is to instantiate MTD devices based on information from the device tree. Therefore the physmap name is replaced everywhere within the file with "of_flash". The file itself and the Kconfig option is not renamed for now (so that the diff is actually a diff). That can come later. Signed-off-by:
