EDAC, altera: Fix ARM64 build warning

2018-08-03T05:55:21+00:00

[ Upstream commit 9ef20753e044f7468c4113e5aecd785419b0b3cc ]

The kbuild test robot reported the following warning:

  drivers/edac/altera_edac.c: In function 'ocram_free_mem':
  drivers/edac/altera_edac.c:1410:42: warning: cast from pointer to integer
	of different size [-Wpointer-to-int-cast]
    gen_pool_free((struct gen_pool *)other, (u32)p, size);
                                             ^

After adding support for ARM64 architectures, the unsigned long
parameter is 64 bits and causes a build warning on 64-bit configs. Fix
by casting to the correct size (unsigned long) instead of u32.

EDAC, mv64x60: Fix an error handling path

2018-04-13T17:48:30+00:00

[ Upstream commit 68fa24f9121c04ef146b5158f538c8b32f285be5 ]

We should not call edac_mc_del_mc() if a corresponding call to
edac_mc_add_mc() has not been performed yet.

So here, we should go to err instead of err2 to branch at the right
place of the error handling path.

EDAC, altera: Fix peripheral warnings for Cyclone5

2018-03-22T08:17:48+00:00

[ Upstream commit 25b223ddfe2a557307c05fe673e09d94ae950877 ]

The peripherals' RAS functionality only exist on the Arria10 SoCFPGA.
The Cyclone5 initialization generates EDAC warnings when the peripherals
aren't found in the device tree. Fix by checking for Arria10 in the init
functions.

x86/cpu: Rename cpu_data.x86_mask to cpu_data.x86_stepping

2018-02-22T14:43:55+00:00

commit b399151cb48db30ad1e0e93dd40d68c6d007b637 upstream.

x86_mask is a confusing name which is hard to associate with the
processor's stepping.

Additionally, correct an indent issue in lib/cpu.c.

EDAC, octeon: Fix an uninitialized variable warning

2018-02-17T12:21:19+00:00

commit 544e92581a2ac44607d7cc602c6b54d18656f56d upstream.

Fix an uninitialized variable warning in the Octeon EDAC driver, as seen
in MIPS cavium_octeon_defconfig builds since v4.14 with Codescape GNU
Tools 2016.05-03:

  drivers/edac/octeon_edac-lmc.c In function ‘octeon_lmc_edac_poll_o2’:
  drivers/edac/octeon_edac-lmc.c:87:24: warning: ‘((long unsigned int*)&int_reg)[1]’ may \
    be used uninitialized in this function [-Wmaybe-uninitialized]
    if (int_reg.s.sec_err || int_reg.s.ded_err) {
                        ^
Iinitialise the whole int_reg variable to zero before the conditional
assignments in the error injection case.

EDAC, i5000, i5400: Fix definition of NRECMEMB register

2017-12-14T08:28:22+00:00

[ Upstream commit a8c8261425649da58bdf08221570e5335ad33a31 ]

In the i5000 and i5400 drivers, the NRECMEMB register is defined as a
16-bit value, which results in wrong shifts in the code, as reported by
sparse.

In the datasheets ([1], section 3.9.22.20 and [2], section 3.9.22.21),
this register is a 32-bit register. A u32 value for the register fixes
the wrong shifts warnings and matches the datasheet.

Also fix the mask to access to the CAS bits [27:16] in the i5000 driver.

EDAC, i5000, i5400: Fix use of MTR_DRAM_WIDTH macro

[ Upstream commit e61555c29c28a4a3b6ba6207f4a0883ee236004d ]

The MTR_DRAM_WIDTH macro returns the data width. It is sometimes used
as if it returned a boolean true if the width if 8. Fix the tests where
MTR_DRAM_WIDTH is misused.
