treewide: Switch DEFINE_TIMER callbacks to struct timer_list *
This changes all DEFINE_TIMER() callbacks to use a struct timer_list pointer instead of unsigned long. Since the data argument has already been removed, none of these callbacks are using their argument currently, so this renames the argument to "unused".
Done using the following semantic patch:

DEFINE_TIMER(_timer, _callback);
@change_callback depends on match_define_timer@ identifier match_define_timer._callback; type _origtype; identifier _origarg; @@

When CONFIG_NWBUTTON_REBOOT is disabled, we get a warning about an unused variable:
drivers/char/nwbutton.c:37:12: warning: 'reboot_count' defined but not used [-Wunused-variable] static int reboot_count = NUM_PRESSES_REBOOT; /* Number of presses to reboot */
Using if(IS_ENABLED()) instead of #ifdef around the user makes the code nicer to read and avoids the warning.

char: nwbutton: open-code interruptible_sleep_on
The nwbutton driver uses interruptible_sleep_on to wait for buttons getting pressed after we enter the read() function, which is inherently racy and cannot be fixed by using wait_event without changing the driver's user space interface.
Instead, this patch just uses an open-coded variant of the same interruptible_sleep_on() call, so the driver behavior doesn't change but we remove the sleep_on family from the kernel.

llseek: automatically add .llseek fop
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer.
The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek.
New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file.
The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle.
Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window.
Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this.

- Use timer macros to set function and data members and to modify expiration time. - Use DEFINE_TIMER for global timers and do not init them at run-time in these cases. - del_timer_sync is common in most cases -- we want to wait for timer function if it's still running.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling.
Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not.
(*) Various IRQ handler function pointers have been moved to type irq_handler_t.

[PATCH] replace cad_pid by a struct pid
There are a few places in the kernel where the init task is signaled. The ctrl+alt+del sequence is one them. It kills a task, usually init, using a cached pid (cad_pid).
This patch replaces the pid_t by a struct pid to avoid pid wrap around problem. The struct pid is initialized at boot time in init() and can be modified through systctl with
/proc/sys/kernel/cad_pid
[ I haven't found any distro using it ? ]
It also introduces a small helper routine kill_cad_pid() which is used where it seemed ok to use cad_pid instead of pid 1.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

char: nwbutton: open-code interruptible_sleep_on The nwbutton driver uses interruptible_sleep_on to wait for buttons getting pressed after we enter the read() function, which is inherently racy and cannot be fixed by using wait_event without changing the driver's user space interface. Instead, this patch just uses an open-coded variant of the same interruptible_sleep_on() call, so the driver behavior doesn't change but we remove the sleep_on family from the kernel.
