e721a45fbe microblaze: Get early printk console earlier
1. Register early console as standard console
2. Enable CON_BOOT console flag to ensure auto-unregistering by the kernel
3. remap_early_printk function remap physical console baseaddr to virtual space

Usage specific function for console remap is done after memory initialization
with IRQ turn off that's why there is not necessary to protect it.

The reason for remapping is that the kernel use TLB 63 for 1:1 address mapping
to be able to use console in very early boot-up phase. But allocating one TLB
just for console caused performance degression that's why ioremaps create new
mapping and TLB 63 is automatically released and ready to use.

Add cpuinfo support for the new MicroBlaze option permitting userspace

Emit a noisy warning at bootup if this is enabled, because bad user code

c11389406f microblaze: Fix unaligned value saving to the stack for system with MMU
Several registers weren't saved correctly to the stack.

Unaligned expection for system with MMU stores
value in ex_tmp_data_loc_X address which is load to registers r3.
The next step is to move this value from r3 to a destination
register which caused unaligned exception. For several registers
this value was directly moved to the register.

For example for r28:
by "or r28, r0, r3"

but register r28 was rewritten when kernel returns from exception
handler by value saved on stack.

This patch changed r3 saving to the correct address on the stack.
For example for r28:
by "swi r3, r1, 4 * 28"

When kernel returns from the exception handler, correct value is restored.

571503e100 Merge branch 'setns'
* setns:
  ns: Wire up the setns system call

Done as a merge to make it easier to fix up conflicts in arm due to
addition of sendmmsg system call
2011-05-28 10:51:01 -07:00
Eric W. Biederman
7b21fddd08 ns: Wire up the setns system call
32bit and 64bit on x86 are tested and working.  The rest I have looked
at closely and I can't find any problems.

setns is an easy system call to wire up.  It just takes two ints so I
don't expect any weird architecture porting problems.

While doing this I have noticed that we have some architectures that are
very slow to get new system calls.  cris seems to be the slowest where
the last system calls wired up were preadv and pwritev.  avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h.  frv is
behind with perf_event_open being the last syscall wired up.  On h8300
the last system call wired up was epoll_wait.  On m32r the last system
call wired up was fallocate.  mn10300 has recvmmsg as the last system
call wired up.  The rest seem to at least have syncfs wired up which was
new in the 2.6.39.

v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com>
v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com>
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
v7: ported to Linus's latest post 2.6.39 tree.

85f60ae4ee dt/flattree: explicitly pass command line pointer to early_init_dt_scan_chosen
This patch drops the reference to a global 'cmd_line' variable from
early_init_dt_scan_chosen, and instead passes the pointer to the command
line string via the *data argument.  Each architecture does something
slightly different with the initial command line, so it makes sense for
the architecture to be able to specify the variable name.

All these functions can be below address 0x10000. If they are, wrong
vector table is genarated because jump is not setup from two instructions
(imm upper 16bit and brai lower 16bit).
Adding specific offset prevent problem if address is below 0x10000.

cd3415779b microblaze: Do not use "la" pseudo instruction - use addik instead
"la" pseudo instruction is only translation to "addik".
Use directly "addik" which is described in the MB reference guide.

6e83557c38 microblaze: Remove r0_ram pointer and PTO alignment
r0_ram pool was used for saving/restoring register
content if hw exception happen. This poll was replaced by
pt_pool_space with PT_SIZE size.
Based on this change SAVE_STATE_ARG_SPACE was removed which
caused that PTO offset is zero that's why is also removed.

r0_ram space was used as scratchpad by v850. In early
Microblaze Linux developing phase was this part of code
blindly copied.
