alpha: kernel: osf_sys: Set 'kts.tv_nsec' only when 'tv' has effect

alpha: Wire up all missing implemented syscalls

2015-05-26T17:01:50+00:00

And still left the missing unimplemented syscalls as warnings. The
related warnings for missing implemented syscalls:

  :1241:2: warning: #warning syscall getrandom not implemented [-Wcpp]
  :1244:2: warning: #warning syscall memfd_create not implemented [-Wcpp]

alpha: Fix bootpfile and bootpzfile make targets

2015-05-26T17:01:50+00:00

Fix the bootpfile and bootpzfile make targets to creat BOOTP images.
Both targets were broken due to some missing defines to re-map ELF
constants. In addition the old code used the generic vsprintf function
of the kernel which we now replace by a simple and much smaller
implementation for the bootloader.

alpha: copy_thread(): rename 'arg' argument to 'kthread_arg'

2015-05-26T17:01:49+00:00

The 'arg' argument to copy_thread() is only ever used when forking a new
kernel thread. Hence, rename it to 'kthread_arg' for clarity (and consistency
with do_fork() and other arch-specific implementations of copy_thread()).

alpha: delete non-required instances of

2015-05-26T17:01:48+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

alpha: don't use module_init for non-modular core code

2015-05-26T17:01:47+00:00

The srm console is always built in.  It will never be modular,
so using module_init as an alias for __initcall is rather
misleading.

Fix this up now, so that we can relocate module_init from
init.h into module.h in the future.  If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.

Direct use of __initcall is discouraged, vs prioritized ones.
Use of device_initcall is consistent with what __initcall
maps onto, and hence does not change the init order, making the
impact of this change zero.   Should someone with real hardware
for boot testing want to change it later to arch_initcall or
console_initcall, they can do that at a later date.

smp, alpha: kill SMP single function call interrupt

2015-05-26T17:01:46+00:00

Commit 9a46ad6d6df3b54 "smp: make smp_call_function_many() use logic
similar to smp_call_function_single()" has unified the way to handle
single and multiple cross-CPU function calls. Now only one interrupt
is needed for architecture specific code to support generic SMP function
call interfaces, so kill the redundant single function call interrupt.

Everything in arch/alpha/include/uapi/asm/types.h is protected by
"#ifndef __KERNEL__", so it's unused for kernelspace.

alpha: clean up unnecessary MSI/MSI-X capability find

2015-05-26T17:01:44+00:00

PCI core will initialize device MSI/MSI-X capability in
pci_msi_init_pci_dev(). So device driver should use
pci_dev->msi_cap/msix_cap to determine whether the device
support MSI/MSI-X instead of using
pci_find_capability(pci_dev, PCI_CAP_ID_MSI/MSIX).
Access to PCIe device config space again will consume more time.
