kexec: remove CONFIG_KEXEC dependency on crypto

2014-08-29T23:28:16+00:00

New system call depends on crypto.  As it did not have a separate config
option, CONFIG_KEXEC was modified to select CRYPTO and CRYPTO_SHA256.

But now previous patch introduced a new config option for new syscall.
So CONFIG_KEXEC does not require crypto.  Remove that dependency.

kexec: load and relocate purgatory at kernel load time

2014-08-08T22:57:32+00:00

Load purgatory code in RAM and relocate it based on the location.
Relocation code has been inspired by module relocation code and purgatory
relocation code in kexec-tools.

Also compute the checksums of loaded kexec segments and store them in
purgatory.

Arch independent code provides this functionality so that arch dependent
bootloaders can make use of it.

Helper functions are provided to get/set symbol values in purgatory which
are used by bootloaders later to set things like stack and entry point of
second kernel etc.

Nothing sets function_trace_stop to disable function tracing anymore.
Remove the check for it in the arch code.

Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP

2014-04-07T23:36:11+00:00

If the renamed symbol is defined lib/iomap.c implements ioport_map and
ioport_unmap and currently (nearly) all platforms define the port
accessor functions outb/inb and friend unconditionally.  So
HAS_IOPORT_MAP is the better name for this.

Consequently NO_IOPORT is renamed to NO_IOPORT_MAP.

The motivation for this change is to reintroduce a symbol HAS_IOPORT
that signals if outb/int et al are available.  I will address that at
least one merge window later though to keep surprises to a minimum and
catch new introductions of (HAS|NO)_IOPORT.

The changes in this commit were done using:

	$ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/'

tile: double default VMALLOC space

2013-09-16T19:47:14+00:00

With per-cpu data as well as loaded kernel modules coming from
the vmalloc arena, we get close to the line all the time and
occasionally need more than we had, so just double it up by default.
