Subject: MIPS: Rewrite <asm/div64.h> to work with gcc 4.4.0.
|
||||
X-Git-Url: http://www.linux-mips.org/git?p=linux.git;a=commitdiff_plain;h=a1b68289997030df64cba8478d5767fe10e42a58
|
||||
|
||||
MIPS: Rewrite <asm/div64.h> to work with gcc 4.4.0.
|
||||
|
||||
The inline assembler used on 32-bit kernels was using the "h" constraint
|
||||
which was considered dangerous and removed for gcc 4.4.0.

When init is started it is SIGNAL_UNKILLABLE. If it were to get an
|
||||
address error, we would try to send it SIGBUS, but it would be ignored
|
||||
and the faulting instruction restarted. This results in an endless
|
||||
loop.
|
||||
|
||||
We need to use force_sig() instead so it will actually die and give us
|
||||
some useful information.

From: Wu Zhangjin <wuzj@lemote.com>
|

|

the gcc 4.4 support for MIPS mostly refer to this PATCH:
|
||||
http://www.nabble.com/-PATCH--MIPS:-Handle-removal-of-%27h%27-constraint-in-GCC-4.4-td22192768.html
|
||||
but have been tuned a little.
|
||||
|
||||
because only gcc 4.4 have loongson-specific support, so, we need to
|
||||
choose the suitable -march argument for gcc <= 4.3 and gcc >= 4.4, and
|
||||
we also need to consider use -march=loongson2e and -march=loongson2f for
|
||||
loongson2e and loongson2f respectively. this is handled by adding two
|
||||
new kernel options: CPU_LOONGSON2E and CPU_LOONGSON2F(thanks for the
|
||||
solutin provided by ZhangLe).
|
||||
|
||||
I have tested it on FuLoong(2f) in 32bit and 64bit with gcc-4.4 and
|
||||
gcc-4.3. so, basically, it works.

MIPS: allow disabling the kernel FPU emulator
|

|

This patch allows turning off the in-kernel Algorithmics
|

FPU emulator support, which allows one to save a couple of

precious blocks on an embedded system.

Subject: [PATCH] MIPS: fix loading of modules with unresolved weak symbols
|
||||
|
||||
Loading of modules with unresolved weak symbols fails on MIPS
|
||||
since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'.
|
||||
|
||||
Modules: handle symbols that have a zero value
|
||||
|
||||
The module subsystem cannot handle symbols that are zero. If symbols
|
||||
are present that have a zero value then the module resolver prints out a
|
||||
message that these symbols are unresolved.
|
||||
|
||||
We have to use IS_ERR_VALUE() to check that a symbol has been resolved
|
||||
or not.

||||

||||

Subject: [PATCH 2/3] I2C: at24: add kernel interface for reading/writing EEPROM
|
||||
Date: Monday 25 August 2008
|
||||
From: Kevin Hilman <khilman@deeprootsystems.com>
|
||||
To: davinci-linux-open-source@linux.davincidsp.com
|
||||
|
||||
This patch adds an interface by which other kernel code can read/write
|
||||
detected EEPROM.
|
||||
|
||||
The platform code registers a 'setup' callback with the
|
||||
at24_platform_data. When the at24 driver detects an EEPROM, it fills
|
||||
out the read and write functions of at24_iface and calls the setup
|
||||
callback. The platform code can then use the read/write functions in
|
||||
the at24_iface struct for reading and writing the EEPROM.
|
||||
|
||||
Original idea, review and updates by David Brownell <david-b@pacbell.net>
|
||||
|
||||
Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
